[x] It's plausible. But it's not something I can really test.
[x] Before we go on, it's probably better to restate some facts.
-[x] 1. While possibly connected, the incident with Sayaka, the feather's appearance, and the changes in Oriko's visions are not necessarily related.
--[x] It's quite possible none of it's related, and that this is just a coincidence.
-[x] 2. If feathers is real, it's not necessarily responsible for what happened to Sayaka. It could've been giving us a warning that something... strange was about to happen.
-[x] 3. Oriko was seeing feathers long before I ever constructed a barrier. If you believe she's telling the truth, her entire motivation up to this point was to stop... whatever it is.
--[x] In that case, why not just kill me? She went about an overly convoluted plot to help us fight this thing and a simple solution was right in front of her.
[x] Cleanse yourself. Offer cleansing to everyone else.
[X] "You know what?" *Silently ask for Mami to hand you the feather* "I believe we have an enemy stronger than Walpurgisnacht incoming, and it's messing with us."
[x] Put the feather away.
[X] "It doesn't matter. We can win; No. We will win. We'll beat it, just like we'll beat Walpurgis."
