This is such an appealing combination of laugh out loud funny--Harry's plaintive refrain of 'I've been busy', Luna's excitement over her and Hermione's visit to the library, Ron packing Harry's things for him--and moving--Harry wondering why he had to know the 'jealous, bitter ones' and not his mother, Snape repeating that he doesn't love--or even like--Harry as he sighs in contentment and curls up with him.
I love that you had Ron and Hermione and Luna in the story, and that Luna is as batty and wise as ever. I love that the three of them simply jump in and help Harry figure out what needs to be done, and that Harry is so *Harry-like*, ploughing forward to save Snape even when he doesn't half know what's going on.
