That's interesting. Did anybody else have something stolen from them? (Specifically Night 2) And this (from Wikipedia): "She also is friendly with Spike, who is as protective of her as Buffy herself." With rana, our known scum, being Spike, this makes for an interesting snack of thought. If she wasn't absent, and thus likely to be modkilled soon (beet? *nudge nudge* ), this would have been enough to go after her right now.

As of the others: as I can confirm the stories of both FT and Isaac, they're in the clear for now. (Plus: FT was both hammer and the first vote for rana)
Taiga: yes, you're getting tired of the "only non-human" thing, I understand, but you'll have to agree it is something worth noting. On the other hand: you did get rana's vote against you way before you were in any danger of really getting Lynched.
Bergioyn: Vanilla, but might get powers later? With only so few information, this sounds strange. He was quiet on voting on Day 1 until the deadline was coming down on us. At that point he voted for rana, but I wouldn't call it too much of a stretch to say he bussed. He was quiet on Day 2, which would fit a lone scum, and didn't get involved in voting until he was sure he wouldn't be looked at strangely for voting for a Town (i.e.: he hammered Stephen).

So, at this point, my list of suspects, in order is 1) DK, 2) Bergioyn, 3) Taiga.
