If visiting Iris on the Josy route is a Christmas Day/Christmas visit event, I'm interested to see the other options (also feel sad for Neil!).
Visiting Derek's house again on the Maya route could be nice, hopefully reconcile between Tremolo and her Dad a bit.
Sage.... IDK.... could see her just spending time in Tremolo's room or something (wouldn't imagine them both going back to see Neil again so soon but it's possible I guess).
Going back to Jill's house would be interesting, definitely want to see more about her family and hopefully finally have the reveal about the house.
Bella is not gonna be in the mood most likely after the locked room but we shall see

.
Then we've got all the "Others" girls to consider...
