I feel like an idiot for not seeing this sooner. Very recently I felt smart for having a capitalized Thought that Luna knows all the alignments. (Assuming Adam is telling the truth, if I were scum the game would be over and she knows her alignment, so the other two are by process of elimination.)
Then I only just now caught the fact that UniqueScreenname's claim is impossible. Again assuming Adam isn't lying, there are two scum, me, and Luna. No room for another vanilla townie. So I'll be executing her for sure. Anyway, that's why I asked for more claims. If the other scum has thought of this, they'll say they're not a Sailor. I thought it was worth asking because asking it doesn't cost me anything and I can explain later. The thing is, if you're scum and haven't thought of this then claiming a Sailor is the obvious thing. I hadn't thought of it until just now, so maybe they still haven't. I might as well give them a chance to mess up.
EDIT: Oh, and also I'm the real Sailor Jupiter. Forgot about that. Now I feel *really* stupid for not catching the lie earlier. I'm glad I haven't called her on it in the thread, though, because then I would lose my excuse for asking for role names. Or maybe I should and just pretend to be just curious, since then they'd know there's a 0% chance of being counterclaimed if they say they're one of the Sailors....
You know what, forget it. The only other townie already knows who the scum are and there can't possibly be a case where I have to choose between the two of them. I'll dispense with the secrets and tell them all everything.
