@@funkymonkey7252 That's why the "role swap" is interesting. Think about what made Sans so lazy in the original. And why he seems more energetic now...
You can both betrayal kill muffet and koffin and they will both be saved by sans. If u want more details go below Both of them, there’s the black screen of when sans teleports, then he’s saving the person. In the muffet fight, he gets out of the web, papyrus said « you could do that all this time » and sans said something about letting the humans deal with it (and weirdly papyrus agreed with sans), he says sorry to muffet and muffet is irritated When sans saves koffin k, he takes the hat and said something like « ik he’s a villain but you can’t do this » then continued to be good old sans to koffin But it’s not all, if u betrayal kill sans, there will be a black screen with « one more chance », if u do it again, papyrus will be angry and if u betrayed koffin and muffet he will say something like « yes, u were in danger with koffin and muffet, but there was no danger here ». Sans says it’s alright and that he will explain what he explains normally at that moment. So he says what he normally says but in an oversimplified way. You can’t hang out with sans after that, but pacifist is probably not removed from u
