It was Kristin. Whoops, sorry for the spoiler.

I am not sure we will ever know. At one point I thought I knew, then I thought I knew it was someone else, and am now frankly clueless. If it had been some drive-by loony I wouldn't care. Knowing now that it was one of us, I would like to know. It will certainly influence my interaction (or non-interaction) with this individual.
