WARNING: If you don't want to know what happened in this episode, don't read this photo recap!
Adam and Seg/Brainiac are on the run from a disgruntled Lobo. When Adam tells Seg/Brainiac that he won't be able to mercy kill him, Seg/Brainiac goes non compos mentis for a hot second.
443863
Actually, Seg/Brainiac sucked up into this mindspace, where the two are separate and can talk shop. Brainiac wants to fuse ever more closely with Seg's system and steal precious biological resources, leaving Seg to ponder over the possibilities of this prospect. Intriguing...
443864
When Seg comes out of the green mindspace, he emerges with a plan: He's going to exploit Brainiac's knowledge while the alien is inside his head, without giving up any of the goodies.
443865
Meanwhile, on Wegthor, Val and the rebels have intercepted a delivery of Sagitari breathing devices, among other items, and are getting prepared for a full-scale mobilization.
443866
And Lyta-Zod is petitioning General Zod/her son to go to Wegthor and quell the uprising before it gets any more Kryptonians killed. But General Zod doesn't want her to join the casualties.
443867
Jayna-Zod has finished cleaning up the mess she made when she and Dev dispatched those Sagitari. She wants to know why Dev escaped from Kandor. He tells her that Lyta-Zod became General Zod's right hand woman, and he got disillusioned with the whole corrupt system. This is all news to Jayna.
443868
Jax-Ur has an idea she wants to run by Val-El. If they can mobilize a small batallion of rebels, give them some of those oxygenators, and send them out to the next Kandor drop-off point and Top Site on Wegthor, they might be able to ambush both the incoming Sagitari and put an end to the deliveries all together. Let's see what happens.
443869
Seg/Brainiac has led Adam to this underground lair, complete with tendril machinery. This is where Seg can begin the separation process to fissure him from Brianiac. But when Lobo starts bellowing, Seg/Brainiac becomes Brainiac/Seg again, and enters fight mode.
443870
Brainiac summons Seg back to the mindspace, and questions him about what he's hiding from him (everything, essentially). Seg remains strong, so Brainiac has to pull out the cheap shots.
443871
Brainiac transforms into... Lyta-Zod. This will eff with Seg's mind for sure.
443872
And General Zod finally relents, and gives Lyta permission to ascend to Wegthor. For better or worse.
443873
After Adam kickstarts the separation machine (literally, he kicked it), and a tendril descends from the ceiling and hooks itself up to Seg/Brainiac's brainstem.
443874
That's just when Lobo descends into the lair as well, and tries to seek revenge. He doesn't know that when Brainiac/Seg hooked up to the tendril machine, it activated a forcefield that can amputate limbs. Sucks for him.
443875
Lobo doubles down on the forcefield, whips out his weapon, and decapitates himself in the head because he knows that now the rest f his body will regenerate inside the space with Adam and Seg. Gross but clever.
443876
On Wegthor, Nyssa meets a woman she once had an affair with and who since has become a rebel. Nyssa reignites the spark.
443877
And in the mindspace, Lyta/Brainiac is detaining Seg from overtaking Seg/Brainiac, and proceeding with the separation process. It's messing up the whole works.
443878
Of course, Nyssa used her ex-flame to gain access to her comms, so that she could snoop through the rebel's plans — the ones she's been kept in the dark about. Nyssa, up to her old tricks again.
443879
In the mindspace, Seg regains consciousness just in time, and puts an end to Brainiac/Lyta's shenanigans.
443880
It couldn't have been soon enough. Lobo regrew his body, managed his way past the forcefield, and was about to kill, maim, mutilate, and otherwise destroy Adam when Seg harnesses the power of Brainiac to send him across the room via air mail.
443881
After that, separating from Brainiac is a cinch.
443882
Then it's a matter of activating the Zeta Beam, and Zeta Beaming the heck outta there! Leaving Lobo to do with Brainiac what he will.
443883
And Jayna finds Dev passed out in the snow, and brings him back to her Outlands Chalet to nurse him back to health and heat. It's a moment.
443884
The Zeta Beam beams Adam and Seg to the Outlands. Seg dies a little bit in transit, but it's nothing that a little CPR can't fix — thankfully, Adam's from the future and has that knowledge. But there's no time to lose: they've got stuff to do!
