Rich would be my top suspect. However as I already said unless Ice is lynched and found to be a turned GH (which I'm not sure is a good idea) there's no way of telling if JL is a GH because the evils know lucky's role too.
OK. So JL says he is a GH. Ice says he is a townie w/ no PR. If we lynch Ice we have a 50/50 chance of lynching a townie/or a turned GH. If we lynch JL we have a 50/50 chance of lynching an innocent GH/or a turned townie. Out of the two I'd rather take my chances of lynching Ice over JL because there is no chance of lynching an innocent GH if Ice goes.
I understand the vote is for Lucky right now for which we have a 50/50 chance of lynching a suspected murderer/or a townie. A tough call for the town. But as I said before I really don't see the murderer calling that much attention to themselves. You have to remember that Lucky seemed like he was trying to get people to vote for him last night. I don't see that as something the murderer would do.
