We left last week on a bit of a cliffhanger: Dutch had transported back into the green, and Aneela... out of it. Johnny and D'av aren't exactly elated over this turn of events, considering how Aneela's tried to kill them oh-so-many-times in the past. She's here to help bring D'avin (and just D'avin, with his special powers) back into the green to save Dutch. She doesn't think Johnny can handle it: after all, the green is really just like one living wax museum where all your memories come back to haunt you — and Johnny's got a lot of wax.
To make the return, Aneela needs a ship. So she goes to the shipmaster, Turin, who's also less than pleased to see her familiar face. Turin has a hard time saying no to the sweet-talking, knife-wielding Aneela. But he's going to try: he wants her dead, or under arrest. But mostly dead. D'avin gets Turin to stand down. He gives him the spore weapon, and tells him that if Aneela breaks ranks inside the green, he's to detonate the bomb, and kill them all. Sounds like the kind of Killjoy insurance policy he's used to.
So, as Aneela and D'av are prepping for their incursion into the green, Aneela voices her reasoning behind taking just the one Jaqobis: he's got that repulsion power, remember? For some reason, when the green was in his system, it changed his brain composition forever. And now he's like, super green resistant. Of course, that resistance needs some coaxing — so Aneela sticks a serum in D'av's brainstem. Ouchies.
Next thing you know, they're in the green. Of course, Johnny forced himself into the plasma pool — he won't sit the season finale out! Aneela rendezvouses with Dutch, who shows her a red box she found. Inside it? An apple. That's probably symbolic of something. But... no time to dissect.
And back in Westerly, some kind of weird virus is spreading across the city's destitute — the families of the abducted children. It's also got Pree, who's been experiencing symptoms ever since returning from the Hullen-occupied RAC. Strange. And then, one of the infected goes into a coma. Pree, better watch out! When Turin hears of the news, he puts all of Westerly under quarantine.
Back in the green, the Lady, in the guise of Delle Seyah, makes Aneela an offer: everyone can get what they want, so long as they don't destroy the green. The Lady is just a memory, she can't make it on the outside... yet. The cost for this deal? The Lady doesn't destroy everything and everyone. D'avin finds Dutch, and together they team up to retrieve Johnny. The Lady's been trying to inveigle her way into Johnny's heart by wearing Pawter's dead skin. It's a low blow. The other Killjoys get him out of this heartrending moment.
To acquire supplies necessary for the quarantine, Turin has called up his Qreshi hookup. But they're being snobby rich people, so... you know how fun that is. Meanwhile, in the green, the Killjoys are getting shot at. They need guns. And how are they gonna get those? Why, return to a memory of stealing guns, of course!
Back on the armada, the Qreshi snob tells Turin his real intentions regarding Westerly: blow that sh*t up. It's the perfect plan: they can justify the destruction of that poor, destitute community with the alibi that they're doing it to preserve the universe. Brilliant! Ugh, rich people. Turin's not about it, but his other idea is not much better: use the spore to kill the green. Zeph arrives at the most sensible of the three plans, which is saying something: she thinks she may have concocted a cure, but plans to test it on herself first. Pree doesn't let her: they need a doctor there. So he offers up his own arm.
And back in the green: After trading gun fire for a good ten or so minutes with some unfriendlies in the forest, D'av finally has enough. And he summons his awesome green-repulsion power to make them disappear. This gives Lady the spooks. Sensing imminent doom, the Lady makes one last ditch effort to get Aneela back on her side: offering her... her family.
Back in Westerly, finally some good news! The antiviral worked! Except... it's also robbed everyone who took it of their memory. Unexpected side-effect, that. Worse yet, Zeph herself starts to lose her memory. She's like a doctor, but without remembering going to medical school.
Johnny and D'av come upon the Lady's inner lair, and find her, in Yardeen form, choking D'avin. Looks like Aneela took the bait, and gave up D'av to the Lady in exchange for Delle Seyah and Jaq — now they can be one happy, backstabbing family together! Or is it just part of Aneela's plan to defeat the Lady once and for all? Yes! It was. Aneela gave Dutch just enough time away from the Lady to throw the spore into the green pool, and initiate the destruction of the green. Oh damn! The Lady is not happy about that. So she and Aneela do battle.
The Killjoys make it out of the crumbling lair alive, and reconnect with Aneela. But it's not really her: the Lady knocked Aneela out, and then took her skin. It's a trap! And just when the Killjoys think they've gotten out of the green unscathed, the Lady thrusts her arm from inside. It's not over yet.
Suddenly, we're transported to some strange alternative universe in which Dutch and Johnny are an item... Jaq is a fugitive... D'av is his bounty hunter... And the Lady is out, and taken the form of a little girl. Creepy x1000000000!
