Actually, I've played the same scene in that film (Time After Time) and in (BTTF) 'Part III.. I've had a man from a different time period tell me that he's in love with me, but he has to go back to his own time. My response in both cases is, of course, disbelief, and I order them out of my life. Afterwards, I find out I was wrong and that, in fact, the man is indeed from another time, and I go after him (them) to profess my love. It's a pretty strange feeling to find yourself doing the same scene, so many years apart, for the second time in your career.
