In normal route, I think Noelle will open a fountain to try to save Rudy or something. Either hospital or Holiday House. I mainly think this because of Queen's foreshadowing of the dark fountains opening (Kris opened one at the end of Ch 2, Susie in Ch 4, so Noelle will make one next). Also will be more likely since Susie thinks they should tell Noelle the truth asked include her on the adventures. I don't think that'll be the entire dark world, though.
