> Dump everything in our room.
Plan A: Find Sanae, see what we can do about dreamtown. I suspect something is down, given it cursed us but Sanae never seemed to have problems.
Plan B: Go find the Dragon God. I can't imagine he'd want to ignore this, and might well take a little joy in thumbing his snout at Yukari.
EXTRA TASTY PLAN C: We know our mother is dead, and can see into the future. Let's go make an special request of Higan to talk to her about that. They aren't in a position to refuse outright, given they're in trouble too.
CRAPSHOT PLAN D: Makai has a goddess. Makai may well be in the shit too.
I really wanted to keep those shards to see if they could somehow help, but unless we can get Ran to fetch them for us we're stuck on that. Plan A is a given, and we can ask Tenshi for a favor to get Iku to help us (Tenshi is a snot, but at least she's an honest snot). Plan C is interesting and I'd like to try it if we can't immediately figure anything out with Sanae, but D is pretty much a Hail Mary throw.
For now, the idea that's popping in my mind is seeing if Sanae can set up her own successor in the dream world, but I don't even know how exactly that would work.
As for telling Konngara... I think it would be a better idea to wait: Reimu is VERY angry and emotionally vulnerable right now, Konngara is still pissing off Reimu with her terrible communication skills, and that talk will take a LONG while. It would be a good idea to tell Konngara something in the mean time, but I don't think it should be that she regained her memories per se.
There's something else I was thinking of but I can't remember it.
