I'm Xenophilius Lovegood. Night one I watched Citrus as he was visited by Azzywhatzit, louiswill, and Damus. I therefore trust Damus because no Death Eaters have any reason to target someone Voldy was killing, and if he was the Dementor he would have died. However, this means Pluvialis is scum, since there are only 4 town left: Dumbledore, Snape, and two others. Since Damus visited someone he can't be Snape, and I'm another too, so there is no room for Pluvialis to be telling the truth.
