Four (Tobias Eaton)'s Lover Type is Crystal

Divergent. The Confident, Adaptable Lover.

Four approaches everything, including Tris, with the analytical mind of someone who has trained himself to notice details others miss, real Crystal behavior. His confidence is quiet rather than loud, earned through competence instead of bravado. He adapts fast when situations shift, whether that means changing tactics, plans, or even the name he goes by, and that same flexibility makes him surprisingly easy to grow alongside in a relationship.
