There's no way Two is an SK. Either that, or there's some part of the role he hasn't revealed.
Two claims to be an SK that kills during the day if he correctly guesses a person's game, but revealed as an SK if he guesses wrong. This role is completely stupid, because it is only effective if people mass-claim. If no one claims early, which Wojjan would have anticipated since he implied mass claiming would be bad, he is forced to guess (and probably get it wrong), and then immediately lynched.
This role is also completely ineffective against mass claiming. Most of the games with mass claims had them happen on Day 2. This role would do nothing to stop it because it would already be lynched and dead on Day 1 after a wrong guess.
Basically, it comes down to a bastard role that says "If people mass claim, you win. Otherwise, you lose Day 1". I highly doubt such a role exists.
Part of the role exists though. He claims to have killed Swiftwolf and no one countered the claim, so it was definitely made by him.
