Tobias pokes at Tris's tattoos while she's asleep.
Tris wakes up, and she and Tobias decide that Tobias should teach Caleb to shoot a gun. It would stink if he died before he could sacrifice himself for them.
Everyone has a bang-up time playing with handguns. Then Tobias goes to see Uriah one last time.
Tobias runs into Matthew along the way and asks him why the heck is he helping, anyway? ("It's not like this book ended up having a love triangle. Why are you still here?")
Matthew tells a horrific story about a girl seen as genetically damaged who was beaten up really badly and died. He hasn't forgiven the Bureau since.
