Snape/Boy Who Lived Deux! I was waiting for Snape to get his head out of his arse and work with Neville - Potions *needs* Herbology, if nothing else, for the ingredients! Surely Neville knows how to approach plants better than Snape! That and, it is always good when Snape learns something surprising - such as that Neville *is* talented, even if he seems to explode his cauldrons all over Snape's last nerve ending!
And I love Headmaster!Snape! (even though at times he acts like he needs Harry to kick his arse back into line!^^)
