Tris is trying to get comfortable in this new relationship. Its all new to her and Tobias. She knows she liked him more than she probably should; that he needs so much more than some small abnegation transfer. Tobias loves the ground Tris walks on; would do anything to protect her and make her happy. He has his baggage, and he carries it with him on his back. They think they don't deserve each other but oh how they need each other. (Al is alive, parents can see their child if they make it through initiation, and there was no war!!)
