what's her motive? why does she want to cause the roaring? how is the roaring contextualized by december being the knight? are previous chapters recontextualized by december being the knight? does she have a vendetta? did somebody wrong her, and if so who? what impact will her being the knight have for susie? how do her interactions with the knight culminate in a satisfactory manner.
where is dess living? at home? in the woods? in the bunker? do people know she's still in town? why is she fuckhuge and floating? is she only like that in the dark, and if so why do other characters maintain their natural proportions? how would she get undyne into the bunker without being overpowered?

you could answer a few of those questions with paranormal stuff but that really cheapens what has so far been a very grounded story with hometown being "real".

personally I think the knight is the man with pink and gold eyes (i.e. a heavily teased new character) and that he's going to use what he finds in the bunker to attempt a red wedding event at the festival.
