Also, I'm very curious to see how Ralsei will behave around prophecied stuff in future chapters now that the cat is out of the bag. Will he be like "oh btw Susie something really bad is supposed to happen to that guy" and Susie will actively try to stop it?
With the whole pink and gold thing with chapter 5, it seems likely that FRIEND will play a large role in it. If FRIEND really is the Tail of Hell, what will Ralsei's reaction be to it? Or will it only directly reveal itself to Kris for now? Because it really seems like something Ralsei would be worried about. Esp when you consider how dismissive he was about Spamton and his connections to FRIEND. Seems like a real pain point...
Also would be fun to see Susie dialogue for if we saw some of the hidden prophecies in ch4. Like recognizing Asgore as the "flower man" or being like "Hey isn't he supposed to grow a beard or something?" about Jorkington.
And if some horrible shit is supposed to go down in chapter 5 (which pacing-wise I think the end of ch5 will be the lowest point for ths heroes) and Susie can't stop it, how will she react? I think seeing Susie down in the pits might be the thing that snaps Ralsei out of his fatalism, if only just enough to help Susie shine once more as the beacon of hope that she's meant to be.
