Jesus christ. Am i going to have to copy and paste my own arguments? This is the last argument ill make on this thread involving sans.
What part gave your interpretation more credibility than saying that it's teleportation? We know for a fact that he can teleport, so I'll just call Occam's Razor and say that is teleportation too. I never made the argument of occams razor and it doesnt even work for you here. It is not a fact he can teleport. The only thing he has shown that is close is forcing you to return to a specific point. Which is limited and doesnt work on himself.
You give zero proof beyond Sans calling them shortcuts. There is zero reason to differentiate him disappearing from in front of you during genocide, him teleporting your soul around, him teleporting back and forth before Even though papyrus himself has described sans as bending space and their is literally no reason for him to call it a shortcut if he is just teleporting you from a wall to a restaurant in an instant. If he were telling frisk that "he knows a shortcut" and he just walked into a wall and teleported then him saying that he knows a shortcut would not make sense in satire context as frisk would just view himself as instantly appearing in one place without taking any form of route.
Him disappearing is just speed, never once mentioned as teleporting, him
He never once tries to make you believe you didn't teleport but walked, not once. Papyrus directly mentions that he hates how he bends space to skip his traps, and nobody else ever acknowledges it. That isn't proof. Because him walking to the opposite direction is not more plausible even if he were to "shorten space". You literally just proved my point entirely. He is directly bending space to get to certain locations. If he bends the space at grillbys to his location, then yes he would literally be creating shortcuts for himself and those who follow him.
And going back to the occams razor argument. It goes in my favour. Sans has been stated that he can bend space to reach certain locations and skip them (which is spatial manipulation without teleportation). Him taking the shortcut would imply he is also skipping distances the same way that was described before and on top of that is backed up by the fact that he is taking a shorter route. It requires far more speculation to assume he has a teleportation ability which was never directly shown nor described outside sending frisk to the same spot (which is arguably a feat of bending space as well) than it does to say he is bending space to create shortcuts which lines up with his statements.
His other feats of movement cannot be done with space bending (most noteably the stick one) and therefore is more likely a speed feat.
Seriously, did I miss some proof? All I'm seeing is "there is nothing saying that he is not shortening space instead of teleporting" (asking to prove a negative, burden of proof negates that), he calls them shortcuts (Hardly enough proof on it's own. And shortcut can also mean a way to skip something, so... yeah) and that he is trying to hide that he is teleporting (just false, completely. Strawman x3. No, i never made that first argument at all. He is consistently shown through statements that he is shortening and bending space. He could not have achieved supposed teleportation in that scene by bending space. Shortcuts dont involve going from one location to another without any route in an instant. I never said he is trying to hide his teleportation ability. My point is that him teleporting rather than bending space to create a shorter route would completely go against the general idea of him taking a shortcut which he is telling frisk he is taking.
When you go to the annoying dog's room, he teleports in front of you and even questions why your following him, obviously poking fun at the fact that he appeared before you without moving. Papyrus also knows that sans plain skips his traps, and the others don't react to him at all, so no real argument there, either. How does sans asking why frisk is following him prove he is standing still? That if anything would just imply he is actually moving (considering that someone would have to move for you to follow them) and just poking fun at frisks confusion.
