- Toriel is fearful of humans, and will bargain with them to get them to leave, but will fight if they refuse.
- Sans is dead in this AU, and Mae replaces him and presents the puzzles.
- Papyrus is badly hurt, but has no other differences, except he does not train with Undyne.
- Undyne often abuses Papyrus, which Mae protects him from.
