Regarding the execution of Arandor. I believe that he shouldn't be executed right now. If he's a Doctor (although I don't believe he is), then with his 25% chance of using his ability, he's not a threat to us. If he's a Mafia, then he's not a threat either, because the danger from the Mafia will only arise when there are only a few players left in the game. Also, I'd like to point out that it's beneficial for the Mafia to eliminate the Mafia during the day, while it's beneficial for the town to have the Mafia eliminated by the Mafia at night. :) And the 3rd option, if Arandor is an Anti-Five, then he shouldn't be executed at all!
Therefore, I suggest dealing with Arandor later (he's not a threat to us, the town, in any case, and he might even be able to help if he's an Anti-Five), and instead focus on other candidates for execution. I propose executing Madge.
