nice job spelling that cw idiot. anyway.
i feel like what we have going on here is a homestuck type situation, both universes' continuity has been affected by things in the other. let's look at the ending stinger, those were some pretty massive chara vibes, yeah? what if deltarune's universe was one of the "next worlds" they wanted to move on to? if that universe is truly independent from undertale, the events of the genocide route-

-and then he is transported somehow to undertale's universe, which, if we make an assumption, would explain why somebody with such a keen insight into timeline shenanigans, at the point of deltarune, doesn't seem to recall any of undertale. by the time he's in undertale though, he basically knows exactly what is going on.
chara in possesion of kris maybe could have catalyzed those events, giving us a sort of circular stable time loop.

-but also possibly the true pacifist route, and maybe even every other route, could have all happened as well.
you know what other character might also have the ability to transcend, or at least influence other universes? sans. we're pretty sure the stuff in his secret lab alludes to deltarune.
so what if, from sans' perspective, the events of deltarune, whatever they may be, happen first for him (possibly because of chara)-
