I *loved* this! Such an interesting use of the "alive and kicking" prompt - instinct would have told me that it would always be Snape we were finding out was alive and kicking- nice twist there. I loved the Snidget/Snape relationship. It was lovely to see something worming its way under his defenses and becoming his friend. Then, to see it was Harry just made it better (although I suspected it I was never sure.) Makes so much sense that a Seeker should become an animagus Snitch (sorta) lol. So I suppose in this story, Snape gets 150 points and Slytherin wins as he caught the Snitch for good.
Such a sweet story all throughout and such a empathetic look at the horrors of Snape's servitude... especially once he had lost hope. How totally isolating.
