Well I have to vote very soon. Gah, I hate it.
I'm thinking Kit; not only do I suspect her*, it appears others do too. Reassures me that I'm not completely crazy (or that others are too, but then again....) so I'm willing to take the risk as she's one of my top suspects.
Other than that, I'd go for Wilwa or quite possibly Nerwen. Actually, in the opposite order from what I've just listed, though either would be fine with me. I will not vote for any of our fine men folk, save Nog, who appears to be a bit different than usual. Then again, we are in a mad house, so perhaps I'll let him slide.
*I looked over her posts and decided that it wasn't just that one post that bothered me. I'm sorry I don't have time to do a complete explanation.
