Booker’s gotten beaten up (and worse) countless times and never got off on it. Little did he know, that’s not because it’s not his thing. He just doesn’t get off on it when it’s one an enemy hurting him.

When one of the team (could be Quynh if she has him captive post movie, or could be any of the others if they get into a physical fight with him after his betrayal) hurts him, though....well, it sparks an awakening.
