I dunno about its tie to the scratching. The butter knife reference (which I can't recall the exact location of) doesn't correlate to the other scratching incident. It almost seems more coffee house/possumy in some ways. Like where would you die by extreme acts of butter knife? Probably not in your dorm. Or in a geology building to be honest. But you might be buried in a cemetary from those wounds.

As for the RC, given that we know ot wasn't K Boy or Maria ... have we considered it could have been the faculty sponsor herself?
