>>84814384actually it was where they didn't fully remember everything after seeing the lore videos, they just remembered fragments and who they were vaguely, they only got all their memories back fully in the white room at the very end (I think I heard some of them even outright say this when it happened too)
this is excluding Kiara (who decided to explain her giving up on roleplaying by making it where she just got her memories back due to it being normal when phoenixes revive) and Mumei (who made it a plot twist that she had actually had all of her memories the entire time from the start and was just acting)
also my headcanon is that Ame's reaction to the memory was an exception since her head was overloaded by memories of different timelines/timetravel
