I'm not saying that it can't be that Gaster fell into the CORE. I'm saying if we consider the possibility that Gaster created Deltarune, new possibilities open up for us, and we might have an explanation for "Another Him", and some of that Story Potential you keep mentioning.

...Plus the fact that the Deltarune website used to show a snippet of Entry 17 means the two are linked.
