This is about Deltarune, and I just needed to digitally write my theory down-
Alright, so a ton of stuff has been going on with the " Player kris" that is controlling kris throughout most of the game. Kris then rips their soul out to try To stop us from controlling kris. What if in one of the next chapters, Kris finally ACTUALLY breaks off connection with us? What if we form a VESSEL, that was created at the beginning of Delta rune? We then fight with kris, because we need a living vessel to control, and if we don't have kris. . We can't play the game basically. And since Undertale breaks the 4th wall a lot, Deltarune might too. Dialouge for kris could go like " I am not a vessel that you can control" Or " My life will not be a game." I can't really make up something for the foutain that kris creates at the end of chapter 2.
