Meanwhile, Jax-Ur, leader of Black Zero, is busy interrogating Daron-Vex. For what purpose, we don't yet know. But she's got a bone to pick with her former guild-mate, and she's going to torture him until that bone is picked clean.
Lyta and General Zod have found the security lock installed by Val, and able to be opened only by an El. Seg and Jayna arrive to stop General Zod from attempting it. But surprise surprise, General Zod's father is Seg… and he's got El blood running through his veins. Open sesame.
So, back to torture. Jax-Ur was on the science guild, and she had a pretty high position. That is until Daron-Vex started offing the intelligentsia, and she took her research and went underground. Another thing: Daron-Vex is working on something called the "bioradical" and she wants it.
Jayna is keeping General Zod under arrest, so that he doesn't succeed in finding and loosing Doomsday on Krypton prematurely. He sees this as self-defeating, and Lyta doesn't want either of them to kill each other. Too late: General Zod challenges his grandmother to a duel in the old tradition.
Ah, remember that little device Jax-Ur was using to torture Daron-Vex? Well, turns out it has a really long range. She activates it from the underground lair, and sends him into paroxysms, and he crashes his vehicle into a snowbank.
In the Fortress of Solitude, Seg and Nyssa, with Val's help, get to brainstorming their next move. They deduce that Brainiac will be going after the second most active power generator on Krypton: the one behind the protective dome. If that goes down, s*** will hit the fan. So they split up to recruit a defense force.
Unfortunately, it has absolutely no affect on a power shortage that causes the protective dome over a city to retract, leaving the cosmopolis and its people completely vulnerable to extraterrestrial attack.
