I know w alot of you think I'm guily, but to be honest, I'd have to be the dumbest alien ever looking at my post history in this game.

There's a better, more intelligent theory:

I find it odd that a lot of people jumped on Bond at the last minute. I didn't vote for Bond because I didn't think he was guilty, but the smart play would have been for the other alien to jump in at the last second and pile on an alien who they realize is about to be killed by the mob.

That way the real alien appears innocent by helping the mob kill his fellow alien, who was already dead just by numbers...

We know manasecret was innocent, but that leaves

Bluefire
Breakabone
Angrist

Who all piled on at the last second. My money is on one of them as being the alien.

If you look at Bluefire and Breakabone's posting times, they posted just minutes before the end of the round, making them the most suspicious.
