I don't think it'll happen, but I want Dess to turn out to be an evil bitch who's behind most of the conflict happening for selfish reasons. It would be interesting if Noelle and Kris are partially fucked up because of Dess fucking with them rather than them just having lost their perfect older sister (figure), and it would be cool if Susie and Dess have a contrasting parallel where beyond the superficial similarities the two have, Susie is a kind girl who only pretends to be mean because she had a shitty life growing where others treated her poorly, while Dess had a nice, abundant life and loving family but threw it away for edgelord reasons. Also it would be funny if Dess is the Knight and Kris is working for her for reasons that are essentially "I can fix her".
