there are only two more chapters and the dark sanctuary prophecy panels are pretty vague

"they'll hear the ring of heaven's call"
"they'll see the tail of hell take crawl"
"the angel, banished, will finally meet with its desire"
and the ones about the end are basically all we have to work with
also, the prophecy calls for the knight to duel with the heroes "strife by strife" so I think we're getting a rematch

Susie will probably have to find out about the soul, Friend/Mike will probably make a canonical appearance, there'll probably be some weird shit man I don't know. not super useful so let's focus instead on where chapter 5 leaves us

Rudy is gonna be in the super hospital. We don't know if "fell down" means what it did in undertale but I don't think that's even a thing in deltarune? his condition in chapter 6 may or may not completely fuck over Rudyknight but right now I think it still has potential. actually, there's no way to tell if Carol was even telling the truth or just wanted Noelle to get off her ass and come home

and speaking of Noelle, she will visit castle town (probably after class since it'll be a monday. unless she doesn't even show up because of Rudy???) and find out about the dark worlds, and with her in on everything (I doubt she'd refuse helping Susie out with the plan) she should easily be able to get the code in Dess' guitar.

the last code is probably in Alvin's possession. unless that one track is called 4rd sanctuary cause there's gonna be a 4TH sanctuary, I think they'll just sneak around in the church normalstyle

Kris obviously doesn't want it but chapter six could very well take place in the shelter. I know it's pointless to hope for a Gaster appearance but if he's anywhere at all... well, that or the lake, somehow. I still fully believe in toilet theory, I think it was actually strengthened somewhat by what Flowery said before he died, about something happening under the town. As a flower, he'd be able to tell if there was something up with the water, you know. and it would just make sense if there was a pump and stuff for the town's water supply in the shelter, where else would you put that?

and then chapter 7 is the roaring? no way that's not happening, right?

I can give everything some more thought later lmao I need to get out of bed
