Sam could definitely be the Vig, or he could be a mafia or another killer. I'm going to stick to my guns for now (no pun intended). The Daykill thing isn't the strongest argument but the continued role fishing and annoying macros are.

As for my role, I'll gladly reveal it to the town if we all agree to roleclaim (and I'll even go first, but only if we all agree) but I'd prefer at least one freaking day before we get cornered into roleclaiming. I'm certainly not going to reveal it when the person I suspect the most asks for it!
