Man in Yellow card... what was he?
At first, I thought he was symbolic of a Gatekeeper or something, and so he knew Jake shouldn't be there. Then the Sadie facial operation episode made me think he was DEATH. As it turns out, he's a fellow time-traveler caught in his own loop. So my question is, if he's nothing powerful, not a gatekeeper, not Death, etc. Then how the heck does he just manifest himself into Jake's car, seemingly replacing Sadie's sleeping body, so they can have that conversation where we find out he's also a time traveler? That part made no sense. Kinda silly to nitpick certain parts and say it makes no sense, when you're talking about a Time Travel movie. But nevertheless, that part was kind of random.
Can someone shed more light?
