There's a lot here to go over. Some things about Mattchew's claim ring true, while other things make me think Sentinel was telling the truth.
The biggest thing against Mattchew's claim for me is if Risen and Sentinel are scum buddies then what reason would Risen have had to even suggest that Sentinel's claim was false? As it was, everyone else was going along with it. Also what reason would Sentinel have had to say that he didn't jail someone Night 1? He could have thrown out the name of any town or scummy looking player no problem. It just doesn't make any sense to me.
On the other hand, I've had this nagging feeling about BM that he's just been a bad townie the whole time, even though his play looks scummy. I don't quite know what it is, but I just have a hunch. Matt has also been the greenest townie to me so far.
I'm not sure who to believe right now, and that's what it comes down to. The only clear thing to me is that if I believe Sentinel, I will vote BM. If I believe Matt, I will vote Risen. I have some thinking to do, and I don't expect to vote for another 20 hours or so. By then I will have made up my mind.
