A lot of people have been obsessing that Trafalgar Law is Sabo. Maybe, maybe not; Oda's drawing of future Sabo seems to have provided solid proof that he isn't. However, judging from his actions, he must have some past relationship with Luffy which the latter is unaware of. I think even Dance Powderer could agree with that. So what would that relationship be? Theories, anyone?
