This story is pure brilliance. Too many lines to quote, but the Snape-Creevey-Bulstrode interaction in the shop is fantastic. Snape is so himself!
And yet, somewhere underneath it all, she was tenderhearted enough to look after Snape, whose sharp tongue had not been dulled by his tribulations and who seemed to cultivate his caustic temperament just to be contrary. Excellent characterisations of both of them, as well as of Creevey to notice such things. I can see the strange fondness that could be growing between the three; proximity can do that to the least expected people!
Laughter. Snape has never been as much the teacher as he's playing now. The line about breasts! Goodness, you've got him down in a most delightful way.
(surpassing even that incident with Douglas MacDougal, a goat, a bottle of Butterbeer, and a pair of Professor McGonagall’s knickers) This. Requires. Fanfic!
He could sense an object’s yearning to be something else--to be useful--and his empathy enabled him to coax the transformation along with great ease. That is the best explanation of Transfiguration I have ever read; I now understand both Dennis' and McGonagall's ability with the subject.
Beautiful, touching piece. I loved the tender Snape found in the photographs and Dennis' newfound will to live. Fantastic work!
