But they might not need to. Seg has taken General Zod to a communications room, and ordered him to call off the onslaught on Wegthor. Zod says he can't: the solar flare has shut down all the comms. Seg tells him to find a way.
Jax is still miffed that Val pulled the plug on her whole blow-up-everyone-with-a-codex-bomb plot. But he tells her that if he can get Seg to talk to Lyta, maybe she'll come to her senses, and then expose Zod for what he really is: a terrible person.
Lyta makes an offer to the rebels: unconditional surrender, and they won't all be eliminated wholesale. Val is surprised when he learns that Seg already contacted Lyta, and that his charms couldn't penetrate her brainwashed noggin. That's all he's got. But Jax has another plan.
Jax transmits a hologram to Zod of her holding Lyta hostage. When Seg sees this, he loses his wits, giving Zod the opportunity to take the gun and turn it on him. Jax gives Zod one hour to make a decision: either he recalls his troops from Wegthor, or Lyta dies.
Adam and Kem are taken prisoner, and their guard is directed to kill them if the hostage, Lyta, is also executed. Their guard is fiddling with the Zeta Beam, when Nyssa enters, shoots him and sets the guys free.
Brainiac comes to Seg in a vision, and tells him to GTF up off the floor. He does, and interrupts the transmission between Zod and Lyta. Then he and Zod fight with fisticuffs. A nice long fight with choking and flashbacks.
In a turn of events, Jax finds out that rather than retreating, Zod amassed his forces in an underground mine and sent disguised rebels up into the freight elevator as a decoy. That's the last straw, and she slits Lyta's throat on camera for all of Kandor to see.
