Incidentally, I'd like to point out that, had Izzy jumped onto Lari's vote, the other wolf (or wolves) could have popped on before (or even after, if they had HUGE manhoods) and quite possibly secured at least a tie. Fortunately they didn't.
Also, I'm very inclined to think Nog innocent at this point, especially when I consider my above statement. If he is in the pack and knew I was going to reveal a wolf, I think he would jump onto the nearest bandwaggon to save whoever I was going to reveal. (Of course if Shasta was a wolf he'd be doing something very stupid, but that's beside the point.) But at the very least he didn't just say "Oh, I have to go, I'll just vote whoever" and leave; he actually asked me why I had the preference I did and if he should follow it. So yeah, I think we should leave him be, at least unless he does something really nassssty.
