What do you think? I've heard many many MANY theories, ideas, stories arguments, questio- OK I'll just stop there, about which side Snape is on.
But I think we'd all like to tally up once and for all who supports Snape and who doesn't.
You'll notice I didn't put a "Not Sure" choice in. Thats because I reckon that if you have a good think about all the evidence JKR has given us about the situation, you will be able to come to a conclusion.
So what are you waiting for, VOTE!!
(please)
