Well, we now have canon Snape all of one year earlier. I can see how this Snape would be viewed more sympathetically, but still not terribly impressed with his array of reasoning for his actions.
I would very much like to see each of these Slytherin attackers taken down hard, maybe lose a body part for their attempts. Pansy and Draco should have her faces scarred in a way unfixable through magic, etc.
Thanks for writing,
