Okay, so when Thomas wakes up this time, he just hears whispers and sees a blinding light. He's in a hospital.
Thomas hears a man and a woman complaining about how a working gun got into the city. They then decide to "just get on with it" (41.10).
And Thomas passes out "for the umpteenth time" (41.12). We didn't make that up.
When Thomas wakes up, he feels no pain. Woohoo. Then he dozes off. Aww.
Thomas wakes up, and he hears the man and woman talking again.
The woman says that the procedure they're doing might actually be a help to Thomas—and that him hearing them talk is probably a good thing. That way, Thomas knows WICKED will jump in if need be.
Oh, and it turns out that there are only about four or five Candidates that are viable for whatever WICKED's plan is. Hmm.
