What a great voice you give Horace. His observations about Albus not taking sugar or pine-apple, disappointment smeared like the cream on a scone - exactly like him.
And his perceptiveness at Hogwarts. I had hardly expected him not to notice Dobby, who does stand out among house-elfs, but he notices Potter's potion marks as well. And has checked carefully against previous year.
And the whole scene between Albus and Horace, and the inspired use you make of that gratuitous knitting-pattern remark from canon - lovely.
