I feel like people missed the subtext of this scene. Its Kris having to care for their mother post-hangover and showing an already established flaw of Toriel’s seen in the winter alarm clock.
When she gets like this, its her Children who have to care for her. And Thats Bad.
i think that this was genuinely toby realizing that there was no noelle dialogue for interacting with her and desperately trying to get the fangamer guys to not do it
