Something I don't think I've seen anyone else mention is that the reason Alphys moved to town and got the teaching job to replace Gerson was because Toriel recommended her
I don't think Paper Trail was right and Toriel is in on what's going on, but there's an outside chance. Especially if >>720260376 happens and the stuff in the Mantle Game where you enter the bunker and have boss fights with half the town turns out to be major foreshadowing.
