4x01 - Crichton Kicks
The episode begins with the caption "some time later"...from Crichton's facial hair I'd say it has been at least 4 months. Crichton wakes an ancient Leviathan and boards, teaching a DRD to play the 1812 Overture and writing wormhole theory on every flat surface he can find. He is rudely interrupted by a Kalish named Sikozu Svala Shanti Sugaysi Shanu. She warns Crichton that others are following her and he will not survive their attack. Turns out that Sikozu works for a group called The Organization. Her first assignment was to take a half a cycle and learn as much as she could about Leviathans. She figured out where the Leviathan sacred space was and then her job was to lead a group called the Grudeks to the Sacred Space so that they could harvest the toubray out of the old Leviathan Crichton has found a home on. The Grudeks release a "dog" to chase down Crichton and Sikozu and Crichton is bitten in the leg. Harvey makes an appearance while John is walking on the beach and he takes off to chase after some girls. Meanwhile, Crichton has a few conversations with a sun-bathing, Aeryn, who is pregnant. She and John aren't exactly nice to each other, but the conversations are in John's mind, and it is obvious that he is angry with her for leaving. Back on the Leviathan, Rygel and Chiana show up and join the plot to stop the toubray harvesters. Chiana tells Crichton that Grayza, from Into the Lion's Den, has put a reward out on all their heads and she and Rygel has no where to go but back. Chiana also tells Crichton that her powers to foresight have evolved into something else. She can take a moment of time and stop it and exist within it and see the outcome. The power blinds her afterward and leaves her with a splitting headache. In the end, the group uses Chiana's new ability to have her slip by the Grudeks and find the positioning of certain tubes in their work, which when shot with a pulse pistol will ignite, but just enough to destroy the Grudeks not the Leviathan and her charges. Sikozu tries to help Chiana, but instead the two of them end up forcing Crichton to fire his pulse pistol before he is fully prepared. It all comes out a success though. Sikozu learns that the Grudeks lied to the Organization about her and so now she is cannot go back to them, but must first clear her name, making her a permanent member of Crichton's group. John tells the Aeryn in his head that he won't be talking to her anymore and he goes back to work on his wormhole theory.

4x03 - What Was Lost, Part 2: Resurrection
John is rescued from the water by Oo-nii, who takes John to his underwater hideout and proceeds to interrogate him about the Darnaz Probes. D'Argo and Sikozu get rid of Oo-nii, but not before telling John he stinks. Sikozu recognizes the stench as Heppel oil, an aphrodisiac. They surmise that Grayza has had a Heppel gland surgically implanted. D'Argo comes up with a plan to save everyone. John's job was to keep Grayza busy for a couple of arns. Meanwhile, the planet's magnetics are getting worse and Jool tells everyone, they will be dead in 10 arns if they don't escape. Grayza tries to get information from John about the Scarrans and wormhole knowledge. John ticks her off by using Scorpius to anger her and she drags everyone outside to witness Scorpius's execution and burial. John is forced to dig the grave. Braca shoots Scorpius and then Sikozu gets thrown in the hole and verify that he is dead. He is not, and he clues Sikozu into a Peacekeeper command code word that get her in a bargaining position. Sikozu tries to keep Scorpius from being buried, but it doesn't work. While Grayza is again having her way with John, Sikozu helps Chiana, Jool and the Old Woman escape from their cell. After a brief battle with the Peacekeepers, John, Chiana, Jool, Sikozu and Granny help each other out and they escape in D'Argo's ship. Meanwhile, Rygel has Elack and the Pilot convinced to end their lives by crashing into the Peacekeeper Marauders on the planet's surface. Elack almost misses his cue and Rygel barely escapes in a transport, but they all succeed and leave the planet behind. Grayza pursues in the one ailing Marauder left, vowing revenge. D'Argo sends out a probe to throw them off the track and then lands his ship BACK on the planet because it was damaged. Their goal is to reactive the Darnaz Probes to stop the magnetics, but Oo-nii reveals himself as the "bad guy" and tries to stop them. John prevails in the battle with Oo-nii and Jool, Chi and John get the Darnaz Probes back into position and working. With the magnetics on Arnessk gone, the temple AND the priests appear again, having been trapped in time. Jool decides to stay behind and help them catch up on 12,000 years of history. She says goodbye to everyone and shares a last kiss with D'Argo.

4x04 - Lava's A Many Splendored Thing
We open with the crew still in D'Argo's ship Lo'La waiting to rendezvous with Moya. Everyone is very hungry as there are no supplies onboard. Noranti (unseen by the crew) gags something up and then tries to pass it around as food to the crew. She calls it jilnak. At first John won't eat it; he gives it to Rygel. Finally, everyone eats some except Sikozu. They all get violently ill. D'Argo lands on a nearby planet and everyone disembarks and is sick to their stomachs. Rygel crawls into a nearby cave and his greed gets the better of him when he spies a golden amulet. He tries to grab it and is caught inside some kind of trap. John, D'Argo, and Noranti follow him into the cave and are sealed inside when Rygel trips the alarm. Chiana and Sikozu are still outside and try to rescue the rest of the crew but are unable to break through the seal on the cave entrance. John and D'Argo try to free Rygel but are forced to hide as some rough-looking humanoid guys with guns appear. They have force-field protection belts which block against energy pulses but not, later, being hit with a rock by John and D'Argo. These guys take Rygel and seal his body inside an amber-looking substance, only his head is free. Noranti tells John and D'Argo that the guys are Tarkan freedom fighters, good guys, but John and D'Argo aren't so sure. They are right as it turns out. These guys are actually thieves led by a scary-looking creature named Ra'Keel. John and D'Argo try to rescue Rygel but are hampered with crazy Granny Noranti who at first keeps insisting that the thieves are good guys and then suddenly falls asleep. She does end up helping to decommission a couple of the guys with the use of her hallucinogenic dust and a hilarious belly dance. John and D'Argo take the protection belts from the unconscious thieves. Meanwhile, Chiana and Sikozu decide to try to blast through the seal on the cave entrance using Lo'La; they get around the genetic lock-out on the controls by coating their hands in D'Argo's vomit. Through trial and error they figure out the controls and blast through the seal. D'Argo gets Noranti out while John stays to retrieve Rygel. He ends up fighting with Ra'Keel as Chiana enters the cave to get him. With Chiana's help, John manages to kill Ra'Keel by encasing his head in the same amber-like substance that is holding Rygel. He rescues Rygel and frees him from the amber just as D'Argo comes back with Noranti, Sikozu, and the real Tarkan freedom fighters. It turns out that they are the same scary-looking creatures as Ra'Keel, not the humanoid lackeys who were working with him. They are grateful that John and Company stopped the thieves so they give John one of the force-field belts as a gift. Everyone heads back to Lo'La. Once back in space, a message is received from Pilot. He and Moya are ready to rendezvous with the rest of the crew. Everyone looks happy at the prospect of finally getting home.

4x05 - Promises
As the crew on Lo'La is rendezvousing with Moya, John asks Pilot what happened to him and Moya when they were sucked into a wormhole. Pilot says he thinks they were examined, but not harmed, and then released. Noranti feels that something is wrong and says so, because Pilot originally told her he remembered what happened. John and D'Argo are immediately suspicious thinking perhaps the people who sucked Moya into the wormhole are still onboard. John heads in first with Winona at the ready. Expecting baddies, he is undone by the site of Aeryn. John is at first relieved, thinking everything will be all right now that the two of them are back together. But all is not well -- Aeryn has heat delirium ... and a surprise. Scorpius appears; it turns out that he found Aeryn, put her in a coolant suit to control her temperature, and brought her to Moya. Aeryn manages to stop everyone from killing him. Scorpius claims he did nothing to hurt Aeryn, he saved her and had her bring him to Moya so he could help John to safeguard the wormhole knowledge in the event of an all out offensive by the Scarrans, John might possibly use the wormhole tech to sway the outcome. Harvey pops up and insists that John kill Scorpius right away. John puts him off because he knows that they may need Scorpius to continue to keep Aeryn alive. However, John is haunted by visions of Scorpius harming Aeryn including the possibility of his inserting a chip in her head. He goes to see her. She is kitted out like a little Scorpy clone; it's a disturbing sight. He asks how she got sick, but Aeryn won't explain. She'll only say that she gave a promise to keep it quiet. The answers soon appear on their own. A huge ship arrives out of nowhere under the command of a creature named Ullom who says he is looking for "the assassin Aeryn Sun" and claims it was he who caused her heat delirium by dosing her with a genetically coded pathogen for which only he has the cure. He will give her the cure if she will give up the name of those who hired her and her accomplices. Aeryn refuses so John and D'Argo head over to Ullom's ship to steal the cure pretending they are going over to negotiate. Once over there, John and D'Argo try to take the cure but find Ullom is just a hologram projecting his image from another part of the ship. Aeryn tries to settle the issue by shooting herself in the head, but Rygel saves her with a well-timed head-but. John & D'Argo head back to Moya after promising to get Ullom the info he wants. Meanwhile, Sikozu chats up Scorpius trying, it appears, to find an ally since none of the crew (with reason) trust her. John goes to the cooling chamber to try to understand what is happening with Aeryn and gets a nasty vision of an Aeryn/Harvey hybrid. They argue about Aeryn giving up the names of her employers to Ullom. John goes to see Scorpius and finds he and Sikozu talking and jumps to conclusions. Scorpius claims they weren't conspiring; in fact, Scorpius offers to remove Harvey from John's mind. Harvey tries to convince John to leave him intact, but John wants him gone. Scorpius jabs John in the neck with some kind of probe and, inside John's mind, John shoots Harvey. Harvey is gone for good. Scorpius then explains that he has a spy on Grayza's Command Carrier who has informed him that the Peacekeepers have a missile that will kill Moya and allow Braca and Grayza to capture the entire crew. They need to get away, but John won't go without Aeryn's cure. Sikozu has figured out that Ullom's ship isn't as huge as it looks. It is a chameleon and is, in fact, pretty tiny. D'Argo, John, and Sikozu (John thinks they might need a nerd) head over to Ullom's ship with Aeryn. They get Ullom's henchmen to give Aeryn the antidote saying she will give up the names once she is cured. John and D'Argo then disable Ullom's men. They locate Ullom and knock him out. Sikozu reconfigures Ullom's ship to duplicate Moya's biosignature to create a decoy for the PK missile. Everyone heads back to Moya where Pilot shuts down Moya's biologics for a few microts to give the missile time to lock onto Ullom's ship. Once locked it can't be changed. As the missile is fired by Braca, Pilot wakes Moya and they starburst away leaving a confused Braca and a very unhappy Grayza. Safely away, Pilot tells Chiana that the crew must pick one spokesperson as he and Moya can't handle having so many voices giving them conflicting instructions. John and Aeryn meet up on the bridge. Aeryn expresses her happiness to be back on board, to be back with John, but John is preoccupied by a specific subject. He asks Aeryn if she has any other secrets she must keep. Aeryn says no. "So you could tell me... you're pregnant?" asks John in a tight voice. Conflicting emotions cross Aeryn's face, but she doesn't give an answer.

4x06 - Natural Election
In honor of Pilot's request, everyone has taken turns being captain of Moya. It is Rygel's turn at the helm, when they stop to give John two arns to sniff out the wormhole he "feels" is there. He counts down, and just a few seconds late, it appears. All watch in awe. But after the wormhole closes, something hits Moya and everything goes black, even the stars. Pilot tells everyone that Moya feels like she is being burned alive, so D'Argo and John go outside and see the problem, Moya has been taken over by a gigantic space plant that was lurking near the wormhole. The plant is feeding off Moya's metal content. John and D'Argo take plant samples from Moya's hull to Noranti and Sikozu for analysis. Aeryn tells Chiana that she is pregnant, and that John knows about it. But she confides to Chi that she doesn't know if the baby is his. She wants to have the baby tested first. She asks Chi to keep her confidence....big mistake. Chiana searches out D'Argo and tells him and he in turn tells John that the baby might not be his. D'Argo confesses his love of shooting things with Lo'La as he and John got outside Moya to shoot the plant. Noranti realizes, too late, that shooting the plant will only make it attack Moya more. Shooting the plant makes it retreat into Moya and it begins eating Moya from the inside. Aeryn regrets telling Chiana her secret and asks her to forget about it entirely, not knowing that it is already too late. Scorpius realizes that the plant shies away from him and calls everyone down. They quickly realize that it is Scorpy's coolant rods that the plant doesn't like. Noranti and Sikozu start figuring out just exactly what about the coolant rods sets the plant off and everyone else gathers up all the rods they can for their big plan. John and Aeryn take a big bucket of the coolant solution to the atmospheric scrubber complex, where fans can blow it all through Moya. All is going well, but the plant is already in the atmospheric scrubbers and it breaks the fans, which break the bucket of coolant and waste all of it. To make matters worse, Rygel discovers that they has now hovered directly over the opening of the wormhole John found and will be sucked in when it opens again, if they don't get away. Noranti isolates the particular element in Scorpy's coolant that kills the plant and Sikozu tells everyone that that compound is already in Moya. The plan is to have the DRD's fire off the solution once it is filtered throughout Moya, creating a radiation reaction that will activate the harmful element and kill the plant. Everyone leaves Moya on Lo'La to avoid the radiation, except John (who doesn't mind being X-rayed), Chiana (her skin reflects radiation), Scorpy (for obvious reasons) and Rygel (he has to set the DRD's to fire). All is going well, but the wormhole opens and Pilot freaks out just as Rygel is getting ready to fire the DRD's. Scorpy saves the day by releasing Rygel from Pilot's grasp and the radiation is set off and Moya is, once again, saved. Pilot announces the voting for captain and D'Argo is selected. Aeryn goes to John and explains that she's pregnant but not sure who the father is. John immediately think of his other self, the John on Talyn. She tells John that she no longer sees a distinction between him and the John who died on Talyn. This confuses John even more so Aeryn explains how Peacekeepers who become pregnant while on a campaign can keep an embryo in status for up to seven years. So, effectively, she can be pregnant with John's baby or with the baby of someone she "recreated" with before they ever met. John is hurt that Aeryn wasn't straight with him up front, and he tells Aeryn that he trusts her with his life, but not his heart. She asks what she has to do to prove to him that she wants a real relationship with him....and he tells her to come back to him when she has her story straight.

4x07 - John Quixote
On Moya, Sikozu grabs John's chess set and offers to play with Scorpius. He tries to get her to open his door, and she grins slyly at him. Meanwhile, John and Chiana are on a transport pod coming back from a commerce planet. Chiana is playing with some virtual reality games while John broods over his situation with Aeryn. D'Argo radios to say that there's a small problem with Scorpius. Before John can find out what the situation is, he is forced into the game by an over-enthusiastic Chiana. The game is ultra-weird. John finds himself back on the Gammak base from "The Hidden Memory" being led to safety by Gilina. Suddenly Stark appears, and John and Chiana are thrown into another level of the game--one that looks suspiciously like the Mario Brothers games from Nintendo. John wants out, but the standard override, "I want out", fails to yield results. John & Chiana are standing at the base of a tall castle. At the top is Princess Aeryn, complete with long, Rapunzel-like golden hair. John thinks that's pretty cool until he's beaned on the head by a falling television set. They meet the game's avatar--Stark. He takes them into a back area of the program to try to figure out what's wrong with the game. John just wants to know where the heck the game came from. Turns out the game is based off of Stark's brain pattern with a bunch of memories from the John Crichton who died on Talyn thrown in for good measure. The Stark Avatar explains that John must kiss the princess or find a green door to get out of the game -- only he says it in iambic pentameter. John & Chiana have no choice but to play the game. They follow a trail of gold coins to the next level and find themselves in a parking garage (I think it's the same one from "Won't Get Fooled Again.") where they meet Zhaan. Only this Zhaan is not Zhaan. This is a sumo wrestler-like man with a surly attitude and two "loomas" which he "milks" and offers to Chiana and John. Chiana beats him at his own game, realizing the first one offered is acid while the second one fixes John's head which was damaged by the falling tv. Next comes a virtual Rygel in knight get-up who shoots fire out of his bum. He explodes when Chiana stabs him with her sword. Next comes D'Argo as a freaky cross between Hansel, Gretel, and the witch from the fairy tale. He has Jool and another Chiana locked up in a big cage each begging to be the next one eaten by him. John finds a green door and seems to get out, but Chiana gets left behind. John re-enters the game to look for her. He takes an elevator up to the Penthouse where he confronts Princess Aeryn who speaks with a Southern accent and a lisp. She also has a butler, Harvey, and an Ogre for a boyfriend (played by Lani Tupu). Chiana shows up with the ogre, and she and John escape out another green door and find themselves on Moya -- or so they think. Moya turns out to be another game construct as is the Chiana traveling with John. Turns out he's been stuck with the virtual Chiana for most of the game. John heads back to the bizarro Hansel & Gretel scenario starring D'Argo and finds the real Chiana trussed up on the table like a roasted pig, complete with apple in mouth. He frees her, and they go back to the Princess's Penthouse where they defeat Harvey and the Ogre. John thoroughly kisses Princess Aeryn.....and nothing happens. Aeryn isn't the right princess. After all, this is Stark's game, and his princess is Zhaan. John goes back to the garage level and cuts the sumo-Zhaan in half with his sword thus releasing the "real" Zhaan. At least she seems real enough. She looks happy to see John again and asks what she can do for him. She gives him some very Zhaan-like advice and a kiss which releases him and Chiana from the game. Back on Moya it turns out that there was only a small problem with Scorpius's door (was Sikozu fussing with it?). John goes back to fretting over Aeryn so Noranti offers him something herb-like to take away the pain and clear his head, temporarily. We don't see if John takes it, but he runs into Aeryn who tries to joke with him about the game. John just walks right past her without speaking.

4x08 - I Shrink Therefore I Am
John and Noranti are on a transport pod on their way back to Moya. They speak of Aeryn and John has a flash of memories, and then admits that it had been quite some time since he'd thought about her. He tells Noranti that he doesn't need the herbs Noranti gives him, but that they just "take the edge off". John signals Pilot that they are approaching and Pilot informs him that no one is available to meet him in the cargo bay. Aeryn is writing poetry, Rygel isn't hungry, etc. John knows immediately that something is wrong. Coreeshi bounty hunters have attacked Moya and everyone is restrained by powerful magnetic cuffs. They want to capture John and turn everyone in to Grayza for the bounty being offered. Ready to fight, Crichton rams the transport into the invaders' ship, blowing up both vessels. Noranti is ejected into space, but she's taken some herbs that put her to sleep and protect her, and John, wearing a space suit, ejects as well and sneaks onto Moya through an external hatch. John gets into the ducts above the command area where D'Argo and Aeryn and being held, but he sniffs some more of that herb to forget Aeryn and makes some noise. The lead bounty hunter, Axikor, hears him and D'Argo and Aeryn distract them long enough for John to retreat. Axikor reads Rygel's mind and learns what John intends to do. This forces John to try another avenue to defeat the Coreeshi - team up with Scorpius. Together they kill one of the Coreeshi and discover they are covered in body armor and very hard to kill. At the news that John is not going to surrender, Axikor orders his men to "initiate containment procedures." That involves shrinking everyone, except Pilot, and putting them in a metal cylinders which lock into the bounty hunters' body armor. Aeryn tells John what Axikor is doing to them just before she is shrunk. D'Argo snags a comms with his tongue just before he is shrunk and Chi stops time for herself and memorizes the steps taken by the Coreeshi to activate the magnetics and the shrinking devices. John and Scorpy kill another Coreeshi without harming Aeryn and Chiana, who were trapped inside. But, John is injured and Scorpius is captured. Scorpius learns that Axikor is not a Coreeshi but a Scarran, of the ruling class, who wants to capture John and bring him to the Scarrans. He is thrilled once he realizes who Scorpius is and what he is worth, and then shrinks Scorpius, who becomes D'Argo's cell mate. Meanwhile, John is trying to formulate another plan, even though he is injured. When he sees tiny Aeryn, he has to snort some more herb to forget her....it's disturbing to watch him snort the herb because he seems to be addicted to it. Scorpius convinces D'Argo of the Scarran's plan and D'Argo contacts John on the comms to tell him. John turns the remaining Coreeshi on to Axikor and they confront him, and are all killed. John gets the arm of one of them and puts it on and following Chiana's instructions, turns off the magnetic restraints, but before he can get everyone to their normal size, John learns that Axikor has called a Dreadnought. John and Axikor end up fighting, turning themselves small and large and finally ending as John steps on a tiny Axikor killing him. After all is settled, John and Pilot contact Aeryn on the comms and ask her advice, before they go to Captain D'Argo with their plan. The Uncharted Territories are no longer safe for them, nor is Peacekeeper space and with the Scarrans after them, they feel the only "safe" place for them is "tormented" space. Aeryn appears quite shocked by this, but agrees that they should make a course for "tormented" space....but she also warns them that it will be much worse there than many of the places they have been.

4x09 - A Prefect Murder
Moya and crew have been in Tormented Space for a while now, and it's battering Moya something awful. She needs to go into complete shut-down for a few days. The crew have apparently looked at 20 planets before finding one with food and drinkable water. They, with the exception of Rygel, Scorpius, and Noranti who stayed behind on Moya, have been on the planet for at least a few days. Chiana's been causing problems just being her usual randy self and has been banished by the locals. Aeryn puts her prowler on autopilot and sends Chiana off to Moya but Chiana manages to mess with the controls and lands in the forest outside the settlement where she stumbles across Sikozu and Zerbat, the son of the soon-to-be-inaugurated Prefect (Gaashah) who just banished Chiana. There's a whole heap of attraction and mutual affection between these two. While all this is happening, D'Argo counsels Gaashah on how to face the problems he will have as new Prefect. D'Argo also comms John, who is talking with the current Prefect Falaak, to see if Moya is ready to come pick them up. John reports that Moya needs a few more days rest before she can come pick them up. He then tries to contact Aeryn who is being led off by a child to the local marketplace. She's getting these flashes of herself first hitting the child then later, at the marketplace, shooting Gaashah. She realizes she's gripping her pulse pistol, and at that moment she gets up to leave, but stops, turns, and begins shooting everyone in sight including D'Argo who rushes in when he hears the pulse fire. Aeryn disappears from the scene as John arrives along with Zerbat and a priest named Paroos. The clan members blame the "off-worlders" and it looks like we're in for a lynching, when Zerbat steps forward as the new next-in-line for prefect. He claims the right to avenge his father's death and heads off after Aeryn with John in tow and Sikozu following. They split up, and John immediately finds Aeryn. Paroos finds them shortly thereafter and reveals that he believes that Aeryn was used as a tool to start a war by killing Gaashah. Aeryn says she was bit by a bug just before she started getting the flashes of herself hitting the child. Just then John gets bit by a bug as well and has a vision of shooting Paroos. Paroos says there are no bugs native to their planet so they must have been brought by an offworlder. The only other offworlder is E'Alet. Zerbat and Sikozu meet up with them, and Paroos convinces Zerbat to listen to him. They head for the Prefect's castle. Meanwhile, at the Prefect's castle, Prefect Falaak is busy slamming Chiana's head into a table and yelling at E'Alet for failing to control her with his Sgabba flies as well as the others. Turns out Felaak doesn't want to have to stop being Prefect when his turn is up in a few weeks. He hopes to stay in power by creating civil unrest. Felaak storms off leaving E'Alet to release more flies. Chiana uses her vision to see that the flies come from E'Alet himself--his head. On their way up the castle steps, John and Aeryn are bit by more flies and have visions of shooting each other. They manage to get inside and free Chiana just as E'Alet comes in shooting. They both manage to shoot him while getting bit more and more. They then train their pulse pistols on each other. John almost manages to apologize to Aeryn and she to him for hurting each other in "A Dog With Two Bones". "You know, I really thought the coin toss ended badly," John says. "It did," Aeryn replies. Just as they are about to shoot each other, they are tackled by Chiana and D'Argo and wrestled to the ground. Paroos comes in and kills E'Alet, who wasn't dead yet, and John and Aeryn are released from the mind-control. Felaak runs in pretending to know nothing about the conspiracy but is confronted by Chiana, Zerbat, Sikozu and D'Argo. Still prone on the floor, John reaches for Aeryn's hand, and she take his. Felaak jumps out the window rather than face trial. Sikozu and Zerbat take their leave. He asks her to stay; she responds that she would like nothing better than to be rid of Moya and the rest of the crew, but she can't stay. Aeryn kneels mourning by the graves of those she killed. John moves beside her and strokes her hair to comfort her.

4x10 - Coup by Clam
The electrostatic impulses in Tormented Space were slowly driving Moya insane, and the people on a planet called Khurtana could add a Zyntian filtration system to Moya to muffle the space noise. However, they wouldn't help Moya until one of their doctors, a man named Tumii, declared everyone healthy and free of space madness. While Tumii checked everyone on Moya, they were eating the food Tumii brought on board, Qatal Mollusks. As Tumii is leaving, everyone suddenly became sick, and he explained that breaking open a Qatal Mollusk and eating the halves forms a sensory link between those beings who ate from each half and cause fatal food poisoning, the symptoms of which are space madness, an illness the Khurtana's shoot on site. Tumii wanted money and a lot of it and he'd cure everyone. Crichton and Sikozu had eaten one Mollusk, so they were sharing physical and emotional sensations. Same for D'Argo and Noranti; same for Aeryn and Rygel. Since Chiana did not eat a Mollusk, she supervised the mechanic who came on board to fix Moya. Noranti researched a cure, while Crichton, Aeryn and D'Argo went planetside to visit Tumii's office. Thus started a whole chain of events. They agreed to pay Tumii the money, but the color of the mollusk they each ate is the only mollusk that can provide a cure and he only has a purple mollusk. D'Argo and Noranti can be cured, much to the dismay of John and Aeryn. The cure, it turned out was more disgusting than the mollusk, D'Argo and Noranti have to drink each other's urine, mixed with the mollusk-based antidote and then touch, hand to hand, for three arns so that the bacteria can leave their bodies. D'Argo returned to Moya to take the cure with Noranti. As Tumii, Aeryn and Crichton waited for the delivery of more mollusks, the doctor received another visitor who shot him. Tumii survived, but the identity of the assassination brought out a whole new problem. Khurtanan's male population has repressed females in every way and they have spawned a resistance movement. Tumii admits it is these women who've imported the mollusks to use as discreet murder weapons against the male government, giving men "space madness." Tumii discovered their plot and was getting mollusks in exchange for his silence, but their attempt on his life meant that the women were ending their blackmail arrangement. So now the only way to get the mollusks was to approach the women directly. Aeryn and Sikozu took off to do just that, and Rygel and Crichton watched the doctor. But when Aeryn and Sikozu were attacked at the gentlemen's club, John and Rygel felt their pain and knew the girls were in trouble. The women's leader, Selva, knowing that the girls had eaten mollusks, hoped to lure their linked partners into coming to the club. Crichton and Rygel did exactly that, but to avoid being noticed as off-world men, they dressed as females. This episode gets better and better. :-) Meanwhile, on board Moya, Chiana discovers the mechanic is actually a woman and when she is discovered by her male supervisor, Scorpius kills him to save her and Chiana. The filter was installed correctly and Moya and Pilot were relieved. Back on the planet, suspecting that Crichton and Rygel were in the club, Selva told her henchwoman to cut off Aeryn's finger guessing that whoever was linked to Aeryn would also feel the pain and scream, betraying himself. But Sikozu offered her finger (her appendages reattach). John was quiet, despite the pain, and Rygel, by that time had found where Selva had the mollusks hidden and had the two he needed ready to take back to the lab. The food poisoning was taking it's toll and they were close do death, when Scorpius, on board Moya, ate the leftovers of their mollusks and took the poisoning symptoms on himself, allowing everyone on the planet one last reprieve to break free of their captors. John stands up and shoots up the place, creating the diversion they all need to escape. Tumii mixes up their antidotes and they are all cured. But left with two nagging issues, Sikozu willingly offered her finger, when she could have saved herself the pain and Scorpius risked death to save them.

4x11 - Unrealized Reality
Outside Moya, John is floating in space feeling for the beginnings of a wormhole. Aeryn sits watching and studying the English lessons John (on Talyn) created for her. D'Argo finds Noranti putting more of the forgetfulness drug in John's quarters and comms John to try to talk some sense into him. Rygel is up with Pilot trying to convince him to talk Moya into getting ready to travel through wormholes. Sikozu is with Scorpius -- the two forge an alliance. Just then, the wormhole opens but almost immediately seems to destabilize. John calls to Pilot to reel him in with the docking web, but the comms don't seem to be working. Aeryn sees John is in trouble and tries to comm D'Argo to get him. Before anything can be done, John is sucked into the wormhole just as it collapses. John awakens on a small iceflow in a dark sea where he is confronted by an older man who looks a bit like a staid British banker only with eerie, blanked-out eyes. He starts spewing out wormhole and relativity theory so John dubs him Einstein. Einstein says he is there to kill John because John knows too much (and yet not enough) about wormholes. He explains that his people exist in a realm outside the known universe yet intersected by the same wormholes that intersect our known universe. His people were the ones who opened the wormhole and sucked Moya in at the end of season 3. They released Moya and then followed her to John. Einstein explains that the Ancients, who gave John his wormhole knowledge, were members of his species altered so they could survive in the known universe. They were sent to observe and influence as they felt necessary. Now, his species is worried that John has enough wormhole knowledge to be dangerous. Systems of wormholes have uncountable entrances and exits. Some connect places in the same universe and time. Others connect different universes; others, different times, because space is actually space-time, and wormholes are conduits through space-time. For those with wormhole knowledge, the energy signatures of the various pathways become more familiar so it takes a phenomenal amount of concentration to focus only on that which belongs to the known universe and timeframe, realized reality. While Einstein is explaining the nature of wormholes, John hears the voices of many people from his past including Zhaan, Stark, and Jool, as well as DK, an ex-girlfriend, his priest, and his 3rd grade teacher. He also visits a number of "unrealized realities" that are sometimes familiar and sometimes skewed. He finds himself back on that first day aboard Moya where he comes face to face with D'Argo, Zhaan, and Rygel for the first time. Another time John is a Peacekeeper Captain who first questions, then kills, Sikozu, a Scarran collaborator and his prisoner. Then back to Moya where he first meets Aeryn but manages to antagonize her so much she snaps his neck ... A world where Earth is conquered by the Scarrans decades before John's father ever entered the space program and where humans have become slaves and guinea pigs for genetic experiments ... A completely upside down reality where Aeryn is actually Chiana, Sikozu is Stark, D'Argo is Jool, Noranti is Rygel, and Chiana is Noranti. In that world, Crais overruns Moya killing everyone and embracing John as a comrade. John begins to fear the damage he can do to everyone he loves and everything he holds dear. He tells Einstein to go ahead and kill him, but Einstein has gotten to know John and trusts his integrity. He offers John one final piece of advice. He explains that when traveling through a wormhole, it is very important not to arrive back in the place you left, before you left it. If you do, it causes ripples like a stone thrown in a pond. The farther back, the wider and more disruptive the ripples are in the present. He tells John that if he arrives back shortly before he leaves, then the ripple will be small. He must ignore the ripples and focus on the first event that goes wrong (different from his memory of it). If he can fix it, then he will significantly reduce the possibility that one of these unrealized realities will be realized and become the new course of the known universe. John listens carefully and suddenly has a flash of Harvey saying the same thing. John realizes that Harvey and Scorpius both knew this secret about wormholes and that is why Scorpius was, at first so determined to conquer wormholes, and now simply wants to keep the knowledge John has out of the hands of the Scarrans. Meanwhile, Einstein is losing the ability to maintain the iceflow and talks John through finding his focus and concentrating on the familiar signature that will get John back to where he came from, without any outside propulsion--John can get there on his own. "Feel the force," John tells himself. Einstein and the iceflow disappear, and John finds himself floating over the open mouth of a wormhole. He takes a deep breath, closes his eyes, and lets himself go. He speeds through the wormhole and out, back into regular space. John tries comming Moya to get picked up and suddenly opens his eyes and looks around. Moya is nowhere in sight. Instead, he finds himself floating above a beautiful blue-green planet he recognizes; it's Earth. John smiles, thrilled to find himself home until the reality sets in. He's floating hundreds of miles above the earth in space with only a spacesuit, and nowhere near where he was supposed to go. "Oops"

4x12 - Kansas
John tries comming Moya again and finally they can hear him, though no one has any idea why. John tells them to lock on to his signal and follow it when the wormhole opens. It seems as if, unintentionally, John cannot open wormholes as he wishes. D'Argo, Aeryn, Noranti, and Chiana get in Lo'La and follow John's signal, arriving at Earth and picking John up. A quick listen to the radio reveals that they've arrived in 1985. John knows from what Einstein told him that his arrival has probably affected the timeline so they go down to Florida to check on John's family and see what's happened. John discovers that his father, Jack, is slated for the doomed Challenger mission and is set to leave in a couple of days. The group hides out in an abandoned drug house, but they have a small advantage. The next day is Halloween, so their "alienness" can be written off as elaborate costumes. John sets out to correct the timeline error. Unfortunately he sees his younger self yell at his father and drive away and his dad announces that he is leaving for the mission tomorrow. In a run for milk at his front doorstep, John meets his old girlfriend, Kim, and then takes off to talk to himself. He tells his younger self to stop his father from going, to talk to him. The kid gets mad and drives away. D'Argo gets power working at the drug house and they turn on the TV. Aeryn is thrilled to realize her English lessons have paid off and she can read and understand what's on TV. She watches Sesame Street, Rygel is stealing candy from trick-or-treaters and getting high on sugar. Chiana dresses in a little orange dress and hits the streets, running into...who else, the young John Crichton, who thinks she is Karen Shaw all dressed up for Halloween. Meanwhile, on Moya, Grayza and Braca have arrived with a Peacekeeper contingent. Sikozu and Scorpy hide from them, but Scorpy sends Sikozu on without him and stays. He waits for Braca to descend a ladder and confronts him, only to embrace him and kiss his forehead. Braca grabs Scorpius and tells him it is good to see him again. Grayza is finally convinced that John is not aboard Moya, but she leaves behind a predator that Moya cannot sense to wait for Crichton. Back on Earth, a nosy neighbor calls the police on the drug house and Aeryn has a chance to really practice her English and does well, until D'Argo scares the cop and he demands that D'Argo take off his mask. D'Argo knows three English phrases, "yes", "no" and "bite me", which he tells the cop and Noranti has to step in with some "forget" dust and sends the cop on his way. Aeryn seeks out John and tells him that they've been made. John walks by his mother reading tarot cards and he tells Aeryn that she passed away four years before he left and that now he has to go talk to her. He tells his mother to make Jack stay and to not give in like she always does. His mother asks if they've met and John looks wistfully at her, wishing her could say more. With it all coming down to the wire, the group hatches a plan to make Jack stay. John tells them that his father rescued him from a fire just before leaving and then in his worry for his son, opted out of the Challenger mission. They decide to recreate the fire, by having Kim lure the young John to the canal where they get him to go to the house with Karen Shaw (Chiana). D'Argo rigs the house for lots of smoke and Noranti perfects a "sleepy" juice to give to the young John so that he will be unconscious during the fire. Kim does her part and gets young John to the canal, where our John and Chiana take over. Chiana tells John she'll get him to the house, no questions asked, and then she distracts the young John from what they really have planned by having sex with him. Afterward, she gives him the "sleepy" juice and they are ready to go. But of course, something goes awry and the young John loses consciousness and dies. Our John begins to fade away, ala Back to the Future style, because he is now dead and doesn't really exist. He disappears completely but everyone can still hear him. Suddenly, the police arrive again at the door. Ghost John runs off to tell his mother to get Jack over to the house to rescue young John, assuming Noranti can revive him, which she does. Aeryn and D'Argo take out the police officers. Noranti is dusting the officers and young John with "forget" dust and telling them to remember nothing, but can't get to the last officer before Jack arrives. Chiana only has a moment to tell young John to forget everything but Karen Shaw in the back of the 4x4 pickup. They all hide in an empty swimming pool waiting for Jack to get John out of the house, but Jack hits his head on a hanging light and knocks himself out. D'Argo makes a comment that their plans never work and he and John rush back into the house. They get Jack and young John out and go back to their hiding places. When they wake, it appears that Jack rescued John and the timeline is restored. In a comical finish, the one police officer who remembers, describes the aliens and has a pumpkin with Scorpius cut into it, while Mulder and Scully-like agents watch him through the glass. Back on Lo'La, D'Argo signals Moya and she has arrived in Earth's orbit in 2003. They travel through another wormhole and get to her. John gets off the ship and instantly knows that something is wrong. He walks through the hanger doors and there stand a number of official looking people and his father welcoming him home. John pulls out his pulse pistol and asks his father, "Was is a trout or a bass?"

4x13 - Terra Firma
After Sikozu assures John that Jack and the other delegates are human, John greets them and introduces them to Aeryn and D'Argo. It turns out that Moya has been in orbit around Earth for 42 days, and they've been waiting for John to return. Scorpius is absent because he has taken a shuttle pod to the other end of the wormhole so Moya has something to lock onto when she's ready to leave Earth. Sikozu can't understand why John isn't more pleased to see his dad and other humans, but John is worried...his presence poses a huge threat to Earth. John has an emotional reunion with his sister and DK (now married). Chiana, D'Argo, Aeryn, Noranti, Rygel, and Sikozu are enjoying the "hospitality" of the US government who have provided a secured house to stay in. John's sister, Olivia, and his young cousin, Bobby, are making them feel welcome. The government types are given an overview of various PK, Leviathan, and Luxan technology by John, Aeryn, and D'Argo. But things are not all well, John is already arguing with the government guys about how much and with whom the technology should be shared including who should be included in the 500 people who will go for a ride on Moya. Meanwhile, Jack and Olivia are trying to create some normalcy for John so they go ahead with Christmas plans and decorate the house, but all is not well when John's old girlfriend, Caroline, comes to visit complete with mistletoe. She gives him a long kiss, much to the dismay of Aeryn. Jack and John talk about the alien technology and information sharing since he has been appointed IASA Project Director of Extraterrestrial Studies. John feels it should be shared freely throughout the world, but Jack and the government agents feel the technology should be kept a secret; after the events of September 11th, the United States needs to work even harder to protect itself. Later John, Jack, Bobby, D'Argo, and Aeryn go up to Moya. Aeryn asks John if it would be better if she stayed on Moya. Aeryn sees how uncomfortable and unsettled John is on Earth and is just trying to see if her presence is making it worse. John tells her that it's up to her which is no answer at all. John lets D'Argo know that he has no intention of taking any of the humans up on Moya. While the governments are still arguing about who gets to go up, Moya and crew, including John, will be long gone. They've done all they can at the moment, providing Earth with some technology to prepare for the day when other, unfriendly aliens might show up. Meanwhile, back on Grayza's Command Carrier, Grayza communicates with Skreeth, the scary hunting creature she left on Moya. She orders it to gather information about Earth and what John is doing there. Skreeth manages to sneak down to Earth. Skreeth intercepts DK and his wife as they are leaving the IASA lab; the creature kills them trying to extract information on John. Grayza orders Skreeth to retrieve John, extract as much information from him, and then kill him. Caroline and Aeryn have a chat about John. Caroline tells Aeryn that she believes John still cares for Aeryn. Back at the Crichton house, Aeryn runs into John and again asks him if he'd prefer she stay on Moya. She tells him that she's not trying to pressure him; she's trying to take the pressure off. As a tear tracks its way down her cheek, John steps forward as if to kiss to her when suddenly, Olivia screams. Skreeth charges into the house knocking aside first Olivia and then Jack. He goes after Crichton. John and Aeryn attempt to fight it off with pulse pistols, but it's extremely strong. They manage to knock it out for a few moments only. John makes sure that Jack and Olivia are okay just as D'Argo shows up in Lo'La and kills Skreeth. Its seems that D'Argo's keen sense of smell allowed him to discover the bodies of DK and his wife in the garage of the IASA labs. "Merry frelling Christmas" Aeryn remarks. "Amen" John replies. Aeryn confronts Noranti about the distillate of laka pods that John has been snorting to forget her. Noranti reluctantly explains that she gave it to John to help him forget. "Forget who?" Aeryn asks. Noranti just glares at her. Back on Earth, John is saying a tearful farewell to his family. "Take care of my home." John asks. They hug and, wiping away the tears, John walks heads back to Moya and away from his old life.

4x14 - Twice Shy
While negotiating for maps of Tormented Space, Chiana bargains for a slave girl named Talikaa, whom she believes she is saving from a life of misery. Right away it's obvious that there is something wrong with this girl. It seems the people she touches which, by the end, was everyone on board Moya, begins acting strangely. Aeryn slaps Crichton, Chiana and Talikaa flirt, Chiana comes onto to John and then Aeryn. Rygel admits to D'Argo that he's cheated the traders, giving them altered currency chips. D'Argo is extremely angry, in fact, more angry than is normal. They agree to find the trader's ship and rectify the currency situation, when Talikaa begins attacking the crew with a screech and a bite. It seems she's a huge spider and not a slave girl at all. By the time the crew finds the trader's ship, they are all suffering from the effects of Talikaa's bites. The only ones unaffected are Noranti, Scorpius and Sikozu. Though it doesn't take long for Talikaa to rip Sikozu limb from limb literally. Noranti and Scorpius discovered her in time, but Scorpius is also now affected by Talikaa and his Scarran side begins to come out. Weak and sick, the others now realize that Crichton has become pessimistic, Aeryn overly emotional, D'Argo oddly placid, Chiana chaste and Rygel apathetic. Talikaa's bite has stolen the dominant traits that her initial touch had enhanced. The traders on the ship are all dead or dying from terrible swollen bites, but on board their ship the crew discover a medical data file that explains Talikaa's behavior. Her species first enhances then "harvests" the neural energy of each victim's dominant trait. Each victim's stolen neural energy is stored in an orb in her nest for later consumption. So they set out to find Talikaa's nest. John and Noranti lure Talika to Scorpius, the only one she hasn't harvested an orb from, and then they follow her to her nest. John keeps her occupied while Sikozu tries to steal the orbs, but Talikaa hears Sikozu and attacks. John ends up killing her with a mighty powerful pulse weapon. Once all is quiet, Aeryn confronts John about how he's hurt her and given up on them. They fight terribly, until John asks Pilot to check the comms. This takes the comms on board Moya completely offline for 30 microts. Johns tells Aeryn that he believes that Scorpy is still trying to get the wormhole info in his head, that Scorpius is listening with the comms and if he knows that John still loves Aeryn that he will use her against John to hurt him. Aeryn doesn't believe him, but then Scorpius breaks in on the comms the microt they are back online and asks Pilot what is going on. Aeryn realizes that John maybe right. So she and John verbally agree it's over, but smile at each other and kiss. They are back together, but only in secret.

4x15 - Mental As Anything
John and Aeryn are sitting in Pilot's den. John is opening part of his Christmas present from Aeryn. It's a remote control. John wants to stay aboard Moya and watch tv and eat popcorn with Aeryn, but that'll have to wait. John needs to accompany D'Argo, Rygel, and Scorpius to a mental arts training class which will teach them mental discipline which will help them in their work against the Scarrans. Meanwhile, Aeryn, Chiana, Noranti, and Sikozu will be off in search of some needed parts for Moya. All of the participants of the mental training session wear a crystal on their temples. Once the seminar begins, the participants must finish the training. If they drop out prior to completion, the crystal will bore through their skulls and into their brains, killing them. Part of the training involves doing mental battle in a training sphere. John refuses to go into the sphere; frankly, I think it reminds him too much of the Aurora Chair. Suddenly, in the midst of orientation, D'Argo smells something familiar. It is the scent of Macton, the Peacekeeper who killed D'Argo's wife Lo'Lan (Macton's sister) and framed D'Argo for the murder. Everyone wonders how Macton found them (as does the audience), and whether they should leave now. It's too late to leave though, the training session has begun, and they can't leave without the crystals killing them. Scorpius is the first to go into the sphere. He is beaten by the trainer. Next Rygel faces a Charrid in the sphere and beats him soundly. Macton tries to convince D'Argo that D'Argo beat Lo'Lan, that D'Argo couldn't control his hyper-rages and ended up beating Lo'Lan to death. D'Argo almost gives in and believes Macton but manages to control his thoughts enough to ask the instructor for help. Inside the sphere, the instructor takes D'Argo through a series of exercises to try to divine the truth, but Macton interferes. He kills the instructor and enters the sphere. He tries to provoke D'Argo's rage in the hopes of manipulating D'Argo's thoughts. D'Argo almost gives up, but he doesn't. He gets his anger under control and forces Macton to tell the truth. Macton was going to tell the Peacekeepers that D'Argo beat Lo'Lan. That way D'Argo goes to prison, and Lo'Lan gets a divorce. Lo'Lan attacked Macton to stop him, and he accidentally stabbed his sister. He then beat her severely to make it look like D'Argo beat her and stabbed her in a fit of hyper-rage. Macton's mind broken, D'Argo leaves him to suffer, locked in the cage of his own memories. Meanwhile, John's trial consists of being locked in a small, burning hot cage. The heat is meant to acclimate him to the heat produced by Scarrans. Keys are occasionally dropped through the top of the cage. John must retrieve a key to get out. The problem is that the keys tend to drop into the burning coals underneath a grate in the bottom of the cage. John suffers for quite a while, comforting himself by whistling the "Colonel Bogey March" from "Bridge on the River Kwai." Eventually, he manages to suck it up, and, the next time the key is dropped, he yanks up the red-hot grate and grabs the key. He burns his hands badly, but he's out. Everyone heads back to Moya.

4x16 - Bringing Home the Beacon
While the boys were off at Mental Arts Training, the girls went shopping on this odd half moon/half leviathan commerce settlement to buy a sensor distorter for Moya. The distorter would make Moya look like a harmless freighter to anyone scanning her. They make a deal with Rekka, the one in charge of making the distorter, but have to wait four arns before he can deliver the goods. Chiana sets out to follow them, but loses them in the crowd. She goes into a "spa" and learns that among other things that this commerce settlement sells genetic transformations, which means that anyone can be modified to look like someone else, right down to their DNA. Aeryn and Sikozu almost run into Grayza and Braca and some Peacekeepers soldiers. They think Grayza might be there after them, but then a batch of Scarrans and Charrids arrive. They were having a secret meeting with each other. Noranti is sent to find Chiana and warn her and Aeryn and Sikozu spy on the meeting. The Peacekeepers are warned that a Nebari is on the settlement and they go looking for Chiana. So Chiana and Noranti pay to have themselves genetically modified and successfully fool the Peacekeepers. Meanwhile, Aeryn and Sikozu were watching Grayza meet with Ahkna, the Scarran War Minister. Grayza offered the Luxan homeworlds to the Scarrans in exchange for peace and the Uncharted Territories. Ahkna was mainly interested in the supposed PK wormhole technology. Aeryn and Sikozu realize, while listening, that the only thing keeping the Scarrans from launching a full out war was the fear of PK wormhole tech. Aeryn wanted to assassinate both leaders before they signed the treaty, but couldn't get a clear shot and the treaty was signed. But then Ahkna's guards captured Grayza and Braca in a double cross. The girls knew that if Ahkna interrogated Grayza, the Scarrans would learn that there are no Peacekeeper wormhole weapons. This would be great news for the Scarrans, who would invade and conquer. So they have no choice but to try and rescue Grayza and Braca. Chiana goes to meet Rekka and finalize the purchase of the sensor distorter for Moya and Noranti, Sikozu and Aeryn stay to free Grayza. Noranti and Sikozu make it back to the transport pod, Aeryn had stayed behind to cover their retreat, she loses Grayza and Braca in a struggle. Finally Aeryn makes it to the pod and everyone is back aboard Moya, including the boys, back from Mental Health Training. They quickly starburst away from an approaching Scarran Dreadnought, but once out of starburst they realize the Dreadnought is still with them. They have a beacon on board Moya that is allowing the Scarrans to follow. They verify that the beacon is not in the sensor distorter and install it. They assume the identity of a freighter and lie to the Scarrans and the Dreadnought moves away. One would think the danger is over, but John looks to Aeryn and says something in English and she looks confused. He asks her another question and begins to sing the alphabet and she is even more confused. Finally, with no choice, as Aeryn reaches for her weapon to shoot, John shoots her in the face, revealing a "bioloid" - a duplicate Aeryn with a beacon in her head. They realize that Aeryn never made it away from the Scarrans, that she has been captured by Ahkna and could be anywhere

4x17 - A Constellation of Doubt
John and the crew are searching for the planet Katratzi where they believe Aeryn has been taken. However, they aren't having much luck. No one they ask seems to have even heard of Katratzi. Sikozu wants to give up, but Chiana won't hear of it. D'Argo, as captain, declares they will keep looking. Meanwhile, John has been watching an Earth transmission Pilot managed to pick up. It's of a television program called "Alien Visitation," sort of a tabloid TV program all about the crew's visit to Earth. They've gotten a hold of Bobby's (John's nephew) video footage and have intercut it with interviews of various psychologists, anthropologists, scientists, and government officials. While John is watching, he begins to remember having heard the word Katratzi sometime in the past. At first he thinks he heard it from Aeryn, but then he becomes convinced that he heard it from Sikozu. When Sikozu comes to his quarters to try to convince him to give up the search for Aeryn, John grabs her and tries to force her to tell him where Katratzi is. Sikozu is scared and insists that she has no idea where Katratzi is. John finally remembers exactly where he heard the word. It was on an alternate Moya where each of the crew members was someone else (see episode Unrealized Reality). Noranti was Rygel, Aeryn was Chiana, D'Argo was Jool, and Sikozu was Stark. John heard that reality's Stark say Katratzi while he was acting as Stykera for the dying Chiana. John goes to Scorpius and offers him a deal. If Scorpius helps John rescue Aeryn, John will give Scorpius all the wormhole knowledge he has.

4x18 - Prayer
This episode is aptly named, as it begins with Aeryn in a cell being held captive by the Scarrans. She is praying that John will be led to her and rescue her. The Scarrans are torturing her for the whereabouts of John. Aeryn doesn't hold up well under the heat torture, and a Sebacean woman working for the Scarrans quickly finds that Aeryn is pregnant. Thus begins the interrogation to find out who the father is. Sebacean reproductive technology is explained again, and the Scarrans move Aeryn to a holding area with other pregnant women from different species. As we've learned in past eps (see episode Incubator), the Scarrans like to experiment with DNA to make improvements on species, improvements that would benefit the Scarran military. A woman near Aeryn talks to her about the children she's conceived and begins asking Aeryn questions. Aeryn tells the Scarrans that she was a "tralk" and the embryo she is carrying could be anyone's. Then she denies ever having loved John and claims that she was spying on John for another man, but eventually she succumbs to the torture and admits that there was only John. In the end, she discovers that the other woman in her cell is a Scarran spy trying to get information from Aeryn and Aeryn kills her. Meanwhile, on Moya, John and Scorpius travel back through the wormhole that leads to Earth, to find the alternate universe where the Sikozu/Stark is. They find that Moya and board the ship, knowing that all aboard will be killed by the Peacekeepers in less than an arn (see Unrealized Reality). Scorpius kills D'Argo/Jool in an effort to get Stark to help her pass over, but this Sikozu/Stark reveals that he must care about the soul to help the soul pass over. Since it was Chiana/Aeryn that Sikozu/Stark helped before, John and Scorpius find her. John stares at her, knowing she is not Aeryn, and tries to kill her, but he cannot. Scorpius has no such compunction however, and fatally wounds her. Sikozu/Stark helps her soul pass over and in the incantation mentions Katrazi and tells them where it is. John and Scorpius leave that alternate reality just in time to get back to Moya and flee from the approaching Peacekeeper ship that Grayza has watching the wormhole. The episode ends with Aeryn telling her gods that she will no longer pray for help, that she is now willing to make a deal with anyone to save her unborn child.

4x19 - We're So Screwed, Part 1: Fetal Attraction
On their way to Katratzi, the crew of Moya stop at a Scarran border post for a search and quarantine in order to gain the needed credentials to move freely about Scarran space. Once aboard the station, they find out that the Scarran freighter on which Aeryn is being held prisoner is also docked at the station. Unfortunately, it's scheduled to leave shortly. The crew need to do something to stall its departure. Rygel comes up with a plan. He gorges himself and then vomits. He announces that he believes it's a flare-up of a very contagious and potentially deadly disease. Noranti and D'Argo show up posing as doctor and assistant. Noranti manages to give Rygel an actual case of the disease which ends up killing a few of the Kalish (same species as Sikozu) manning the station, but it effectively quarantines the whole station, keeping the Scarran freighter, and Aeryn, right where they are. Worried that Aeryn will become infected and die, the Scarran operative decides to transplant the fetus from Aeryn into Chiana since Nebari are immune. He sends Charrids to Moya to capture Chiana and bring her back to the freighter. They strap both Aeryn and Chiana down and prepare to complete the transfer just as Sikozu manages to shut down power to the station (and also fuse the control panel with some sort of beam emitting from her hand, definitely not a normal Kalish girl!) giving cover to John and D'Argo who stage the rescue mission and manage to free both Aeryn and Chiana. Sikozu and D'Argo manage to steal the needed credentials to get into Scarran space, but Scorpius is knocked unconscious by the Scarran operative and so is left behind while the rest of the crew starbursts to safety. Back on Moya, John waits by Aeryn's bed as she sleeps off the drugs in her system. He falls asleep and begins to dream. Like an old black and white horror film, John finds himself in a crypt. A coffin in the center slowly begins to open. Inside is Harvey! But this isn't the old Harvey, this is Harvey 2.0 who not only reads John's thoughts but also has the ability to broadcast those thoughts to Scorpius. This means that Scorpius might already have all the wormhole knowledge John possesses. Harvey screams for John to go back and rescue Scorpius. John knows he has no choice.

4x20 - We're So Screwed, Part 2: Hot to Katratzi
Aboard Lo'La, everyone is en route to Katratzi, the Scarran base. Rygel is lamenting the plan, and after Aeryn outlines the plan, I understand why. John has built a small thermonuclear bomb which is strapped to his body. Of course, announcing himself at Katratzi, John is welcomed to the peace negotiations between the Scarrans and the PK's, namely Grayza and Bracca.. John announces to everyone that the bomb is wired to blow if he suffers any distress of any kind, even getting too "close" to Aeryn, which he can't seem to avoid. John put his wormhole knowledge on the auction block to the highest bidder. So while John and Aeryn are busy vying to keep the Scarrans and PK's time and attention, D'Argo and Rygel make nice with the station's contingent of Charrids, while Sikozu wins over Katratzi's Kalish administrators. As fate would have it, the Charrids and Kalish hate each other and the plan is to incite a riot to cover their escape with Scorpius. Noranti and Chiana find Scorpius. John and Aeryn, worried he might break soon under the torture, are allowed to see him. Stark who is torturing Scorpy, a loving it (anyone remember the Aurora Chair), hides from John and Aeryn. Minister Ahkna, the Scarran in charge of Scorpius, gets inpatient with John and uses her heat ray on him, almost setting off the bomb. Meanwhile, Sikozu discovers that the Scarrans have a "secret cave." Only one elevator goes down there, and only the Charrids have the security codes to that elevator - or so they thought. With the help of a member of the Kalish resistance, Sikozu gets John and Aeryn in the elevator to check it out. They find that the Scarrans are protecting a flower garden. It is full of the Scarrans' favorite crystherium flowers, much like the bird of paradise flowers here on Earth. When Aeryn and John are discovered in the garden, they claim they'd ended up there by accident. The Scarrans yell at the Charrids for leaving the elevator vulnerable and the Charrids in turn accuse the Kalish of making them look bad. The riot is underway. The Scarran General relieves Ahkna of her duties regarding Scorpius and we discover that Scorpius is a Scarran spy and has been working for them for 10 cycles. The Scarran Emperor releases Scorpius to John and Aeryn, and with the riot in full swing, everyone is making their way to Lo'La, but then Scorpius knocks Aeryn out and throws John to the ground. The bomb begins to tick loudly and powers up, just as Scorpius tells John to trust him. To be continued…

4x21 - We're So Screwed, Part 3: La Bomba
John and the crew find their escape thwarted by Scorpius and the Scarrans. When speaking with Scorpius, John has Harvey filling in other details in his head. Scorpius explains to John why he stopped John from leaving. The Chrystherium flowers are too important to leave in the hands of the Scarrans. Harvey explains why. Turns out that eating the Chrystherium flowers is what changed the Scarrans from brutish, animalistic creatures into the cognizant, intelligent schemers they are. No more Chrystherium and they devolve into mindless animals. Scorpius tells John the only way off Katratzi is to help Scorpius destroy the Chrystherium chamber. John wants other options. He and Aeryn go to Grayza's Command Carrier. While John meets with Grayza, Aeryn visits the medical unit. John tries to convince Grayza to help them without having to give her the wormhole knowledge. It's a no-go. Meanwhile, Scorpius reveals to Rygel and Noranti that Stark is not really Stark; he's a bioloid replica. They need to find the real Stark. Ahkna approaches John with a proposition. If he gives her Scorpius, she will allow John and the crew to go free, immediately. What's in it for her? The Emperor gets the blame for their escape, gets removed from the throne, and Ahkna gets to be Empress. At this point John tries a last ditch plan to get out. He, Aeryn, Sikozu, D'Argo, Chiana, and Scorpius get a hold of a drilling elevator. Sikozu's Kalish co-conspirator gets them an ident chip giving them control of the elevator but is killed by the Scarrans who come after the crew to prevent them from escaping. They head for the Chrystherium Chamber while Sikozu tries to activate the drill head. They reach the chamber and Scorpius tries to destroy the mother plant--the one plant that pollinates the rest and allows them to grow--but it's protected. The Scarrans regain control of the drill elevator and everyone jumps off into the Chrystherium Chamber. With Scarran soldiers on their way down to kill the crew, Sikozu offers them a way out. She is unlike other Kalish. She has a special ability which allows her to burn out the heat producing gland of the Scarrans, killing them. Stuck in the chamber with no way out and no way to adequately defend themselves, the crew urges Sikozu to use her ability, promising that they'll stick by her no matter what happens. Sikozu blasts the Scarrans, killing all four of them. Meanwhile, with things going to hell on Katratzi, Grayza decides to break the flag of truce by sacrificing the lives of everyone aboard the Command Carrier in an effort to destroy the base. Braca argues with her, but she is determined. Braca relieves Grayza of duty and takes command of the vessel. He orders their retreat. Back in the Chrystherium Chamber, Scorpius continues trying to destroy the mother plant but can't get through the shielding. The crews heads back to the drilling elevator except for Scorpius who is really beginning to lose his cool. He nearly takes John's head off, but John manages to drag him along. They use the drill to bore to the surface, but they only make it as far as the Emperor's chamber. Pinned down by Charrid weapons fire, John tries to think of a solution. "How important is it to destroy that flower?" he asks. "I'd trade my life for it." replies Scorpius. "And what about my wormhole debt?" Scorpius sees John's meaning and agrees to release John from their earlier deal if John can destroy the Chrystherium. John re-arms his nuclear bomb and drops it down the elevator shaft below them. The elevator capsule protects them from the blast and shields them from the radiation, but most of Katratzi, including all the Chrystherium plants, is destroyed. Noranti and Rygel have rescued Stark and are back on Lo'La ready to pick up the rest of the crew. Safely back on Moya, D'Argo and Chiana have rekindled their romance, Sikozu starts one with Scorpius, and Aeryn comforts John while he laments the deaths he's caused on Katrazi and fears the deaths he may cause in the future.

4x22 - Bad Timing
After escaping Katratzi, Moya's crew finds themselves followed by Braca's Command Carrier. Braca claims that they intercepted a message from the ruined Katratzi base saying that the Scarrans were on their way to the wormhole that leads to Earth, to subdue Earth and harvest the Bird of Paradise flower that grows there. Scorpius urged John to make an alliance with the Peacekeepers, to deter the Scarrans from moving against Earth. Instead, John sends Scorpius and Sikozu out an airlock over to the Command Carrier while Moya starbursts off to the wormhole. Pilot and Moya even employed an extended Starburst to get them there ahead of the Scarran ship that was already on its way. John's plan was to destroy the wormhole leading to Earth, but he didn't know how, so he spent most of the trip working on equations. Something Aeryn said triggered John's implanted wormhole knowledge and he approached Pilot with an idea - fly into the wormhole just before it opens, piercing the wormhole bubble at it apex and causing the wormhole to collapse in on itself. John would fly to Earth and destroy the wormhole from the Earth side, coming back out by Moya and living the rest of his life with Aeryn and his friends in the Uncharted Territories. It was a big gamble, however, and Pilot told John that his hand eye coordination wouldn't be fast enough to pierce the wormhole bubble at precisely the right time. Pilot was the only one who could do it. So the crew proceeded to detach Moya and Pilot, it was a painful process, but once done, John, Pilot…and Aeryn were on their way to Earth through the wormhole. John landed on the moon, and on his final visit to Earth, took a moment to contact his father and say goodbye. Back on Moya, they could only wait. Most of the ship was dormant, although Chiana, using her special sight, had been able to memorize the most critical of Pilot's functions. The effort had blinded her, but because of it they had enough systems online to track the approaching Scarran Stryker. The Stryker fired at a crippled Moya as it passed, causing severe damage. Then it disappeared into the wormhole, just as John, Pilot and Aeryn entered the wormhole from the other side, successfully destroying the wormhole and the Scarran Stryker. Needing time to heal, the crew landed Moya on a planet called Qujaga, whose oceans contained minerals that would heal Moya's wounds and soothe her pain. Chiana's continued blindest was a concern to everyone. D'Argo watched John and Aeryn float out in the sea on a boat and relayed what was happening to Chiana. Aeryn told John that her baby was released from its stasis and that she was going to have his child. A thrilled John stood up in the boat and yelled to the heavens that he was having a baby, and then he dropped to his knees in front of Aeryn and proposed marriage. A tearful Aeryn accepted. He put the ring on her finger and they were kissing when an alien ship came out of nowhere and circled their boat. The pilot of the ship asked permission from his superiors to subdue the aliens for further study and was granted permission. Aeryn and John watched the ship circle and tried to get back to Moya, but then realized they would never make it. She turned to John and said, "Your timing always was terrible. They kissed, oblivious as the ship fired on them. John and Aeryn turned into crystal and shattered into a thousand glittering fragments, with the engagement ring sitting atop the pile. …To be continued…
