WARNING: This article contains major spoilers for "In Zod We Trust," the sixth episode of Krypton Season 2.
Since returning from the Phantom Zone at the start of Krypton's second season, Seg-El has had a turbulent time. He's found Zod ruling the planet, his love Lyta strangely aggressive and determined to slaughter the Rebellion, and his grandfather Val-El struggling to find a way to save their homeworld, especially knowing Doomsday is on the loose.
However, his biggest challenge comes from Brainiac, with whom he's sharing a consciousness. Seeing Lyta's throat cut and Zod ready to enact full genocide, Seg is left with no choice, and must make a deadly alliance with the Coluan to try to rescue his people from certain destruction. Upon introspection, through, this is a deal that could doom Krypton in ways Seg can't imagine.
Brainiac infected Seg when they escaped the Phantom Zone and became stranded on Colu, fending off Lobo in the process. As Seg made his way back home, he found that Lyta's thirst for blood and obedience to Zod was due to a mental reconditioning. Seg was subject to that too, but ironically, Brainiac's presence to prevent him from becoming a mindless drone.
But with Brainiac still trapped within his mind, Seg sees him everywhere and knows he has to purge this being before it kills him, or worse, takes over his body entirely. When Seg witnesses Lyta's death broadcast across the planet, he knows it's about to get worse, and to save his own child, Cor-Vex, he must strike a deal with the devil if he hopes to turn the tide.
When Seg rescues Nyssa and Cor from Zod, their ship nearly, crashes but Brainiac uploads knowledge to the hero's mind, allowing him to make repairs and fly his family to safety. The villain uses that to goad Seg into a pact, knowing full well the Kryptonian is cynical about his intentions. We simply can't trust Brainiac because he could have made the craft malfunction, but seeing his family in peril has Seg shaken and irrational. More so, he suspects the rebellion led by Jax and Valis fracturing and he needs a Hail Mary to stop Zod.
To prevent a war, Brainiac asks him to take him to his ship so he can upload his mind into his own robotic body and be free again. In return, he'll upgrade Seg, whether it be with weapons or knowledge on how to destroy Zod's regime. There are even hints he can augment the hero's body, which entices Seg, as he knows Doomsday is another imminent threat that not even Zod could handle.
Seg is reluctant to trust the Coluan, the knowledge that Nyssa and Cor could die at anytime, and the pain of losing Lyta, play on his mind. He accepts the offer, even though Brainiac may still harbor ambitions of bottling cities like Kandor. Brainiac gives Seg his word he won't betray him, but no one believes that. Perhaps Seg has his own scheme up his sleeve, but until that's revealed, he's desperate.
He can't afford to lose anyone again, and seeing as Brainiac hasn't killed him or his loved ones since escaping the Phantom Zone, he's making a leap of faith. If it backfires, though, the repercussions will be huge, so all we can do is, like Seg, hope all will work out.
