I mean, Asgore were huge enough to push kris and Susie to the exit of dark world, but Toriel ain't huge and she definitely can't pull the same shit as Asgore, so what she's gonna do to kick her son and Noelle out of dark world for their own safety?
I mean, the whole Asgore's motivation of wanting to prove everyone that he just wanted to protect everyone, did happened only because of the hatred towards himself for not preventing the incident from a past, which is just would not work for Toriel since she never tend to be known as someone who would blame and hate herself for failing at something and make herself think that everyone around blames her, so what's her motivation will be in chapter 5 in that case?
I mean since holidays are the ones who owns church in CR, then there definitely will be Christmas thematic over Halloween in church, which means undyne can't scare the kids like how alphys did, so what she'll do instead of it?
