Maybe someone is telling someone to tell someone to do the killingfoulcoon, did anything happen to you night 1? I ask this because I want to know what my role really is.
Anyway, the only reason we don't know anything about the identity of the killer is because we don't even know the exact structure of the game yet. Everyone, except for one person, has a role that is not what they were told, and only found this out after night 1. We still don't know what those roles really are aside from the fact that they all give no response. (So far we've had roleblocker and doctor, and I doubt there are duplicates, though there could be)
If what everyone said is true, me, foulcoon, rust45, and akrosmir are confirmed insane. animask, Rantai, and Haneii might be sane still (but we don't even know anything about what Haneii is or what he did). rust45 is a cop that distinguishes people by sanity, but there are still at least three other roles that have no response. One of them is the killer. Perhaps another one could be a bus driver, which I suspect would make animask insane, and I don't know what the third (or more) one could be. >.<
One thing I should note is that it is confirmed thanks to rust45 that everyone has a constant role. By this I mean, no one's role changes from night to night. This may seem obvious, but everything is a possibility in this game. =_=//
So far we have
Rantai -> Haneii -> nothing
rust45 -> Haneii -> Insane response
pieguy -> bmin11 (now dead) -> nothing
foulcoon -> pieguy -> nothing
animask -> foulcoon and rust -> nothing
akrolsmir -> ?
Haneii -> ?
We need to find out what akrolsmir and Haneii did, and especially Haneii so we can find out if Rantai is actually curing everyone or not. Ultimately, we need to find someone who acted different after night 1 than before night 1, because that person would have just found out they were the killer. (I don't have any gut feelings yet, because I'm still confused as to what's going on.
