I nominate Robz as the second mime.
How useful is it for everyone to coordinate on giving opinions on who's most likely to be the remaining mime? It's clearly in scum's interests to NK the remaining mime, since they can't prevent the rest of us from handing the mimes an accidental win through lynching, since even if they've worked out strong suspicions between themselves, they can't actively coordinate with the rest of us.
Would everyone "mime-voting" (e.g. posting something "Mime: robz" in bold) on which player they most want
not to lynch help us aggregate information/reads across anti-mime factions? Yes, mafia has in incentive to promote themselves/their partners as "likely mime" too, but if a very-likely-mime candidate survives a couple of NKs, we can start getting really suspicious. And we also have a decent chance of a town vig existing to help matters if we're afraid to lynch.
