Brenda knows some dude named Hans who lives in Denver. He's immune, and he's a doctor. He also used to work for WICKED, but he left because he disagreed with their motives. Brenda herself has never really liked WICKED.
If the gang can get to this doctor, they can have him take the chips out of the heads of Thomas and Minho so that WICKED can't track them anymore.
Sounds like a plan to Thomas.
The next day on the Berg, the group holds a meeting—which Minho calls a Gathering, for old time's sake.
They eventually unanimously decide to go to Denver. But Newt will have to stay on the Berg until they figure out something.
When the meeting finally adjourns, Thomas decides to take a nap. Then he dreams. As he does.
In his dream, Thomas is twelve, and an unhappy man is facing him.
Thomas is being difficult, apparently, and the man is questioning Thomas's motivation to go through with the project (probably the whole WICKED experiment).
Thomas's twelve-year-old self recites the Goals of WICKED, which we've heard about a million times already.
