But I think we both know that the scene was there because JJ Abrams wasn't familiar with the episode A Piece of the Action, and not for any other reason.
No. I don't know that. What I know is that Abrams has bigger fish to fry than slavish adherence to small elements of established continuity. I know that he has to violate some continuity if he doesn't want to have his hands so tightly bound as to make the entire project a waste of time.
