“See you in about 30 years.” That’s the time gap in that part of BTTF in the clip Jaxer posted, that involves the note that ended up preventing Doc’s death the second time around. About. 30. Years. I always thought Emma’s 28th birthday was sort of a random number, but now, I’m just sayin’.
Also, count me among those who were surprised to see Hook in that scene. Wouldn’t think it’d be conducive to getting Rumple to help them if he knew Hook was involved.
