The reason I went for Nod instead of Rev is becuase Nod's reaction would be a better indicator of if they are packies, to test my theory. Rev is obviously the more level-headed player, and could probably handle the situation with a calm disposition. Nod, on the other hand, doesn't seem to deal with these situations well. If they were to be packies, I would assume that in his reaction there would be more flaws. His reaction was violent, to an extend, and apparently knew the issue of defending Rev's agruements would come up, yet he didn't explain that.
Now to address some of your other points:

It seems everytime he posts, it's about the topic being discussed at the time, he hardly brings something new or get back to one of his previous points.
I am pretty sure my last post brought up something that is new, or rather, a new interpretation of an old subject. Most of the players aren't bringing up anything "new" per say either, if thats what you think of it. Also, why is discussing what is at hand a bad thing? I am sorry I only looked back five pages to refresh my memory, but a lot of what was going on at the start of Day 2 never struck me as too strange.
I already addressed his vote on Rev and the fact that he basically dropped the subject on the second day, but the fact that he now chooses to ignore some shaky logic that Rev presented to instead focus on Nod is even more suspicious. He again goes for the topic at hand and totally ignore his previous suspicion.
Well first off, you would complain by looking at Rev's logic that I wouldn't be presenting anything new

. More seriously, I am not ignoring my previous suspicion; where did I say that? I talked about Rev, did I not? I said he is still suspicious, did I not? As mentioned in the first paragraph I wrote in this post, I pursued Nod becuase I think his reaction would be a bit more telling. It is obvious I still have suspicions of Rev because he was mad Ej didn't get lynched so goes blabbing off about how MaHuD is suspicious for not killing a guy. I find that strange, especially since another person who wanted Ej dead is now agreeing with everything he is saying.
The reason he voted Rev on the first day was because he thought Rev was trying to get a bandwagon on an easy target. Now he attacks that same easy target, accusing him of being Rev's packmate. There's something very inconsistent here.
Things change between days, but looking back on it, Revs arguement against Nod on Day 1 wasn't too strong. Packies occassionally will vote on each other, so it isn't strange that such a thing would happen. Plus, in the end Rev changed his vote to Ej. He ignored past suspicion of Nod to try and go for the most likely lynch.
