You're a hookup, someone he intended to never see again.
But then he decided to get out of Blüdhaven for a little while (definitely not to avoid you, that'd be crazy) and he started tracking Bane to a remote jungle and he almost got his head chopped off mid-fight because he was too busy thinking about your eyes, and he knew that what he was about to do was sort of pathetic, but necessary if he wanted to keep his head.
He showed up on your doorstep, flowers in hand, in a fairly decent button-up shirt, and now he's trying to apologize for ghosting you for almost a month straight.
"Hey, babe." He tries the pet name before you the slam the door in his face.
