According to Sans, "our reports showed a massive anomaly in the timespace (Timeline space it seems he's referring to, some sort of visualization of timelines in a space of some sort) ''continuum. timelines jumping left and right, stopping and starting..." "until suddenly, everything ends." "'heh heh heh... that's your''' fault isn't it?" Sans tell us at many points in the game that he feels we can influence time "time traveler." He calls us... on the fetch quest that leads to us learning more about Sans and what happened to him and his timeline and what this means for Gaster's fate and the bro's origin, of course, he's pretending that he's just making a guess, saying " if'' " we had a special power and things like that, but when you fight him he reveals he knew it was you all along. They've done research on this before. (Of course in some no longer existant timelines it was Flowey. But unlike the fandom's interpretation, Sans cannot remember timelines, he can only infer that there was a previous timeline. ) But in this case it was you, and that's the main reason he's followed you, sure he made a promise to Toriel, and as he said, he would have kiled you otherwise, but he had his half a set of flashing eyes on you from the very beginning. So yes. He does. He knows full well the human soul's ability to manipulate all of reality and perform RESETS, SAVES, and LOADS.
