What are some theories you're holding onto until the rest of the chapters release?

(posting this on the undertale subreddit cuz the deltarune one has a karma requirement lol)

like the title says, what are some of your theories you're gonna believe until the rest of the chapters release? mine are:

1. that Dess is the roaring knight
2. Carol is connected to the roaring knight in some way (this ones pretty obvious i know)
3. Gaster is (or connected to) the roaring knight
4. Susie was not supposed to be part of the prophecy, but Noelle

curious to hear what theories you have
