How likely is it that Krusie actually becomes endgame? I know we've been seeing Suselle moments in Chapter 4, with the expectation that there will be more of those in Chapter 5, but there's a certain level of depth to their friendship that Kris and Susie have that Susie and Noelle just lack right now.
I've said this before but given the personality and narrative parallels Susie and Dess have I'm thinking that Noelle's attraction to the former is partly due to a subconscious desire to have Dess back. What if, if Dess is ever saved, Noelle might have the realization that she doesn't really feel the same attraction to Susie as before? Call it a pipe dream but it'd be interesting.
We know that Kris is working with the Knight to try and bring about the Roaring, and it's theorized that this is an attempt to bring Dess back, whose disappearance may be Kris' fault. And this puts him in conflict with Susie and Ralsei. And I feel that by doing so, Kris is ruining a perfectly good chance to move on with his life and his new friends - is risking the end of the world really worth trying to save someone who died long ago? I would say that Susie is more than one-in-a-million, she's someone who you can say nigger around and she'd say it right back, someone who you can just talk about anything with. They've fought and bled side by side, and now he's willing to throw it all away for a chance to fix what might be his biggest mistake? I understand that, but the problem with playing both sides is that you'd have nowhere left to stand at all. Trying to dig up the past to save whatever's left means you might be trapped in a hole with no way out.
