Though I haven't really any reason to doubt it, other than general paranoia. But hey, that's the name of the game.

If a doctor did claim now, I would be pretty suspicious of them since that would be pretty silly. Especially since we just finished urging any roleblockers/docs not to reveal themselves. The doc knows who they protected last Night, and that's good enough for me right now. Furthermore, there are a lot of players and potentially a lot of roles, so it seems likely to me that one person (or communicating group even) can hardly know what all went on overnight. So even if the doc didn't protect Isaac last Night, it's still very possible that he really was attacked and that attack was somehow foiled. Heck, that could even be true if he was a Darkfriend, or a SK.

We have so little information right now it's kind of frustrating. Does any have suggestions about where we ought to go from here?
