Remember when Tris punched Peter in the Amity compound, and the Amity were trying to calm her down and give her serum and Tris said something like (idk the exact wording): "he's crazy. He stabbed someone in the eye. With a butterknife."
We talk about stabbing people in the eye
We envision in to our enemies
And threaten it in anger
Are we crazy too?
. . .
*points at Peter like a little kid* HE STARTED IT!
Peter: Hey, Veronica Roth made me this way!
