What a fantastic story! I love all their interactions here, and how Filius grows in confidence as the story develops and he makes the job his own. The glimpses of the students are lovely - Neville's crush on Pomona, the different crisis styles of the Ravenclaws and Hufflepuffs, and the bullies at Durmstrang - and you've woven the magic so cleverly through it, with all the charms references. Plus the ending is just perfect - good on Filius and Pomona for all their imagination and experimentation :-D
