Well, the mafia will kill me, then. What if he does, and they try to hit me, and they waste a hit? There's a lot of possibilities, but I think the path I chose was the one most likely to get me through this alive, since had I not chosen it, I probably would have died yesterday.
Edit: I just got clarification from Khush: I can not create a tie, but people after me can create one. Essentially, if the vote is 5-1, I can block a vote here, and later, even if the votes appear to be 5-6 (5-5 with the blocked vote,) the blocked vote still stands, because when I caused the block, the vote wasn't a tie. A simpler way to say this is that I can't change a vote with the intention of making a tie upon the vote being blocked. It's a matter of timing, as it stands now.
If necessary to prove myself, we could probably create a vote scenario where I can verify myself even tonight, but it would take the full cooperation of all the players, as well as a unified decision of who the second person to go up against me and "lose" the tie, as well. If the town figured out that, then I'd be happy to vote for myself and cancel my vote as the start of this, and let everyone else play their part to prove my identity.
