Canon evidence for Snape being a vampire

No: HPFGUIDX 35362

Impressive list, Pippin.

A lot of Snape-vampire hints, but taken as a whole the evidence is 
ambiguous and lets us draw any conclusions we want. 

Well, I admit that all these vampire references might easily be a red 
herring--one more example of Snape being not what he seems.

However, I like to think that Snape indeed is a part-vampire. Wasn't 
it your theory that one of his "grandmuzzers" came from Transylvania? 
 Sounds good to me.

Why I want Snape to be a vampire: just because of morbid curiosity. I 
can't help wondering what would happen if Snape's non-human origins 
were revealed and fat would *really* hit the frying-pan.  Hagrid in 
this situation drunk and sobbed for a week, Lupin quietly resigned, so 
what would Snape do?

One more thing: JKR seems to treat the vampire theme differently from 
the themes of the other known HP part-humans.  Hagrid turned out to be 
a half-giant without any foreshadowing at all; Lupin and Fleur's 
part-humanness (humanity?:)) was revealed in the same book they had 
first appeared (PoA and GoF respectively), but look what happens with 
vampires: numerous foreshadowings throughout the four books and still 
no vampire appearance. A lot of suspense, I would say.  Might it 
possibly mean that vampire topic will turn to be very important for  
the overall plot of the series?

If Snape turns out to be a vampire, than his life story might be a 
sort of opposite of Voldie's life story and in line with the main 
moral statement JKR makes in the series: that our choices, not our 
origins define what we are.  Tom Riddle, 100% human, handsome and 
talented, chose to take a dark path and became a full-fledged vampire: 
he maintains his livelihood using others' blood (drinking unicorn 
blood in HPSS, using Harry's blood in GoF).  Meanwhile Snape, a 
vampire, and therefore considered evil by cultural default, chose a 
right path and ended up not only being a character milllions of fans 
are crazy about, but also able to see his reflection in a mirror (GoF) 
:D.

Cheers,   Ana.
