By the way, it's not a fact that the biker pulled the journalist's hair. Although, according to the description, "bully" is most likely the case. In that case, since no one is protecting Omega, it means he is a mafia member after all... Or an unpunishable doctor, or a hidden role without citizenship.
The hamster owner could also be a hidden town role that fights against non-citizens. But the option with the maniac looks better. And the hidden town role probably went to the Werewolf.
By the way, Lizard wrote something about a hidden town neutral role that operates all night. Maybe it's some kind of general buff, or rather, an anti-buff for the mafia... It seems that it hasn't been used yet.
