The fact that he invited so many people into the QT without REALLY knowing their alignment points towards him being a mafia trying to get everyone who he knew was town's role claims, as well as the fact that he's been silenced ONCE. He's obviously trying to come off as a threat to the mafia, but I think that he has to be one because he's lasted this long and hasn't been silenced on a regular basis. I could see why not before the doctor died, but now there's no reason for the mafia to not have killed him if he was town.
And now there's his wanting to lynch Elysion, which makes absolutely no sense if he's town. He knows perfectly well that Elysion visited Bouy the night he was killed, which a mafia probably wouldn't do, and that she did the cop check on Gliscorman. She COULD be a mafia, but Human's really pressing his luck trying to lynch her without getting suspected.
