Ha, ha! I love Severus' humour. (He is joking, isn't he?) ;)
How on earth did Minerva get him to attend in the first place? Blackmail, surely; the meddling, old cat...
Because, there is Harry. And no matter how tight-lipped and sharp-tongued Severus might present himself, Harry will cut right to the heart of it - and of Severus - and go for it - and Severus' heart. ^^

Thank you, pekeleke, for sharing!

P.S. Just re-read and saw that Harry got Severus to squeak! Yay! Go, Harry, devour him!!
