The kids are resisting, and they're doing a pretty good job of it.
Unfortunately, a woman who has a launcher is left untouched in the scuffle, so the fight doesn't last too long. Pretty soon they're all being restrained, and Newt and Minho are taken to separate rooms.
Janson orders Brenda to come down into the room because she's been insisting that she help with the procedure. Hmm, either that's very good, or that's very bad.
When Brenda gets to the room, she whispers to Thomas that he needs to trust her like he did back in the Scorch.
Brenda's ordered to sedate Thomas. Ruh roh.
Before she sedates him, Brenda tells Thomas the truth about the Scorch: she was acting, and so was Jorge. They both work for WICKED, and they're Munies.
Then Brenda gives Thomas a quick little hint at her plan: she's going to do the procedure really quickly, and she asks him if he's ready.
In other words, Brenda's gonna do something other than sedate Thomas, and he needs to be ready to spring into action.
