My ultimate Suselle prediction is that their friendship and sprout of romance are going to go to shit in chapter 5 for various reasons but them having to team up after Kris goes off the reservation and rebuilding it from scratch, this time with both being honest with each other from the start and not hiding their weirdness and we finally get to see Susie use Noelle as a projectile
Also depending on whether Ralsei joins up with Susie or goes with Kris Berdly might join the party and we'll have a B-team of Susie, Noelle and Berdly for a bit
