Carter returns to GD. Henry says the abnormal activity in the kids' brains is increasing as they become more tired. Carter wants to make sure they're kept awake so they don't build another weapon tonight, but Allison walks up to say they're too late.

The GD security team is trying to hold a bunch of zombie-like kids back from leaving the sick bay. Allison says they were all asleep, and then got up at the same time and tried to leave. They've been like this for the last hour, but only now did Allison apparently decide to let Carter in on it. Carter turns Zoe around gently and tells her to get back to bed. She just yells, hits him, and turns away. Carter looks furious, like he's about to ground Zoe's ass off for something she obviously can't help. Henry says the kids' brains are flooded with neurotransmitters like adenosine, ATP, and serotonin. Wait, serotonin? So it's like the kids are all rolling on ecstasy? What fun for them! Allison says the kids can't handle the stress to their brains for much longer before there's permanent damage, but they still don't know what's causing this or how to stop it, nor have they been able to contact Zane to find out what he's learned. I guess that product placement cell phone service isn't so great after all. Carter gets a call from Jo. Before she can talk, he tells her that the kids are back in their trances. "They're not the only ones," Jo says.

Carter pulls up to the tower site, where Jo is waiting for him. This time, a bunch of zombie adults are dropping their household items off. Suddenly, the towers turn on as Carter spots a familiar face among the zombies -- Zane.

The next morning, Carter returns to GD and tells Tess, Allison, and Henry that the towers are humming now. Allison orders Henry to program the geo-satellites to measure for abnormal gravitational pull. He leaves, and Carter says he wants to tear the towers down. Tess thinks that's a terrible idea, considering the fact that they still don't know what the towers are for or if it's even safe to destroy them. Carter thinks the towers are responsible for all of this, but Tess points out something rather obvious: the kids were affected before the towers existed, obviously, since they had to be affected to build them in the first place. Carter says that's true, but things have gotten worse since those towers were built. Well, do you know what's even worse than that? An anti-matter explosion. Keep the towers up. Allison says they have the rest of the day before the trance sets in again, so hopefully that'll be enough time for Fargo and Henry to finish their scans and get them more information. Except that Fargo is probably too busy dealing with more important matters, like calling 911 because Larry looked at his car wrong. Carter agrees, and Tess knows that this is going to call for her very best work and puts her glasses on so as to appear brainy.
