RE: Phase 3
I agree, if Kecleon-X really is the indie we're suspecting him to be, we should eliminate him as soon as possible. We can't risk getting vanilla-ized, or killed, or whatever his ability might be.
Additionally, I have seen a role before, incidentally named the Alien, that can probe one player a night, which basically does nothing besides making them counted as "Probed". The win condition is if all of the living players have been probed by him at some point. So, we could be dealing with a role similar to this, which is harmless, or it could be something more menacing. But I still think he should be the one we go after tonight.
