I'm glad you liked Luna; I like her too; she's got so much for a writer to work with.
Yeah, when I was plotting the story, I did realize that 'Back to Hogwarts' might have to be pointed out to the reader, as it really wasn't a major theme, but did end up being their 'meet again' point.
Thanks so much for reading, kid, and for your support. I'm sure everyone is going to love your Pidders!
