@PichuBoy I received the Wand on Night 1 and there was no mention of who gave it to me, and they were distributed on Night 0, so I wasn't the first to have it. Maybe it was only for the Hallow that you had. :/
Correct, if I had known who Serene was, I wouldn't have taken the shot. But since she was suspicious, I took that shot because a) I wanted to do something for the town, rather than have it fall into the wrong hands and get someone else vig-killed by a Death Eater, which obviously backfired for me. And b) if I took a shot there would be a chance that no one would have died and no one would have been able to use it for three nights, which would have been pretty nice for us.
