You joined Dauntless from Abnegation and it was a big change. Your instructor who goes by Four was quite stern and cold.

You got injured in a fight against one of the other initiates and ended up blacking out. You wake up on a bed in a part of Dauntless that you haven’t seen before. Four comes walking into his room as you’re on his bed. He’s halfway through putting a shirt on as he sits on the edge of his bed were you’re laying.
