Then has the mafia not killed either of them yet?
Last night was the only opportunity so for this game for the mafia to kill. They were able to kill two people, Trojan and EnderWiggin. Ender is a big threat to any mafia team and he was the first person to voice suspicions on Call me Daniel, a mafia member. He was also the most experienced player in the game. Trojan probably claimed to the wrong person and we don't know exactly who he claimed to.
Also, it is highly likely that Tom is mafia. Tom claimed watcher, which conflicts with Blu Ross's claim of watcher and said that Ness, who has established a town network, was the mafia roleblocker. The thing is Blu rose was checked by the cop last night and is confirmed town. I personally doubt that there are two of any blue roles in this game, so that leaves Tom as our top suspect, since Blu Rose is confirmed (blue could be godfather, but if she was mafia there's only a one in three chance that she would be godfather, if we're assuming that there's four mafia in the beginning).
Please vote for Tom since he is mafia
