I always find Ethan619 suspicious. I mean, on every game I've played with him he has been at least a little suspicious. He alwasy posts things like "hopefully its a good night for the innocents" and stuff like that. Apparently he is more involved with this game and that's something we may have to look carefully.
I don't really think we should lynch Jigsaw. Nobody has counter claimed his character and I'm assuming the character is good enough and important enough to be in the game as an innocent.
