Things hit the ground running an hour after the end of Divergent.
Okay, they actually hit the ground sleeping… Tris wakes up from a dream in which she replays that time she shot and killed Will.
Tris, Peter, Marcus, Caleb, and Tobias (or "Four," if you're nasty) jump off a moving train and walk toward Amity headquarters. Where is it? Amityville? Will there be horrors there?
Yeah, there kind of are. The Amity Representative, Johanna Reyes, has a thick scar across her face. We wouldn't judge, but Tris sure does: "She would have been a beautiful woman if not for that scar" (1.33).
An Amity nurse gives Tris a salve for her shoulder and takes Peter, who has a bullet wound, to the hospital ward.
Tris sees a lot of her old friends and neighbors, like Susan, in the cafeteria.
An Abnegation gives Tris a pink drink and says it will help her sleep a dreamless sleep. Naturally, Tris says, "Thank you, but no." Oh, wait. She totally doesn't.
Tris drinks the pink drink. The last thing she remembers before falling asleep is someone leading her to a bedroom. (Stranger danger, Tris. Stranger danger.)
