If Sans is in some way communicating with Gaster, which I think could be the case, wouldn't that solve the whole "our reports" thing, rendering the "Sans talking with himself in other timelines" unnecessary?

I mean, he says he notices these things from your face and reactions, so he has a method to learning this stuff without needing to be told. Not to mention that he says that it's weird when the protagonist immediately turns around and shakes his hand without being prompted (if he already knows all of this stuff, then why make the comment?).
