You need to ask next time, just to be sure. Anyway, Spartacus tried to defend Grant pretty heavily only to change his vote and opinion in the last minute when it was obvious Grant couldn't be saved. Kane did it a too a bit earlier but I see Empty forgot to count him. It's worth noting that Grant also tried to sway the suspicion towards Predom, Candles and Destroyer. I think it's pretty safe to say that those four who voted Grant are innocent. That secret -me vote seems pretty useless to me, I mean what's the point? Or maybe it is a warning that someone is suspicious of me. Or he just wanted to try out his awesome powers.
