Four

Four is Tris's love interest in ''Divergent Series. ''

History
Four is first seen helping Tris get out of the net after she jumps through the hole into the Dauntless compound. After all the initiates have come in, he introduces himself as the instructor to the transfers. Four show Dauntless Transfers fighting technique. Four supervises their training, showing them how to fight with weapons, as well as hand-to-hand combat. Tris' fellow initiates, Christina and Will, both comment that Four seems like someone to stay away from. Four tries to help Tris out with her combat abilities, though Tris is wary to trust him, initially. During Tris' first fight, against Peter Hayes, when Tris starts being beaten badly, she notices Four leaving the room. When she comments to him about this, he says it "wasn't something I wanted to watch."
