Yeah, I have very little hope for Snape's survival in Book 7. *sigh* His death is almost guaranteed, even if it does turn out that he's actually loyal to Dumbledore after all (or, more accurately, not loyal to Voldemort).

So I better enjoy all the Snape fics now, before he's dead forever (although, I suppose if Sirius can show up after being killed by a curtain, then Snape can show up after being killed viciously by someone in a fit of righteousness).
