I really enjoyed this story. I guess I'm the odd one out for feeling this way, but I thought the story generally pretty creepy (in a good way). I kept expecting someone to regain their memory and realize they were all war heroes under Ministry control or something like that, like they'd all been obliviated to keep them out of the way. I wondered if the other members of the psych group were HP characters, and if so, who they were. This was a truly fantastic piece for managing to keep me on the edge of my seat, even though there ended up not being a Big Reveal moment at the end. Well done!
