In Divergent, Tris just got a simulation and in the simulation she got attacked by crows. Then when she went back to the dormitory Peter as reading a news paper about the faction Abnegation from Erudite. The Erudite and Abnegation are enemies and Abnegation is Tris' former faction. Will had to pull Tris out of the room so he wouldn't attack anybody.
Why would somebody make fun of somebody else? I think that's very rude. Tris seemed very mad when she tried to attack Molly. Luckily, Will got her in time.
