And another thing to note is that during the scene at Grillby’s, after he walks away, if you talk to Grillby again, he says “your food is probably cold by now.” What does that mean? That means time has most definitely passed during the Grillby scene and, frankly, that’s the most supporting scene you got going for yourself.

The shortcuts only seem to work on willing participants because Sans never had a reason to forcefully teleport you in the first place. No matter what Frisk is...very compliant to walk alongside Sans so that they can take his shortcuts. He wouldn’t have a reason to do it outside of a fight because Frisk just went along with it.

Also they do technically end up in the same spot, because Sans moves back to the middle of the screen near the end of the fight. We know for a fact that his teleportation can be used short range because in some parts during the overworld he openly teleports. I recall one part where Sans is just off screen, and you can walk back and forth and find that Sans moves to a different spot by the time that the screen scrolls. Technically they just put Sans’ sprite on the map twice but in-universe this implies teleportation.

Also, I personally find it a stretch, yes. Sans seems to have some sort of scientific background or something. He doesn’t exactly know what’s up with the resets, he just knows what’s happening because...I believe he said his machines “picked up on an anomaly”? Or maybe I’m remembering the dialogue completely wrong but either way, without much proof, it is in fact a stretch to say that he has timestop just because he has some form of temporal awareness that, admittedly, isn’t even that good, because he can’t tell for certain when you’ve reset. Because he never brings it up before his genocide fight, even after you start a new game.
