The idea that Harry created just what he needed to transcend his disfunctional life was so subtly woven throughout the narrative! When Severus explained it, it seemed so obvious, while simultaneously surprisingly evocative of how painful Harry's life must have been to need such a defense mechanism. What I adored was that Harry had enough logic in creating the memory bond that the reader followed along eager (at least, I did)!
I have to say that I was totally taken aback when the press back-off Harry so easily, and I thought that Draco's succumbing to Harry's impeccable logic(?) was a bit of a surprise, and was so happy when you explained it!
It was beautiful that though it was just in Harry's mind, Severus was still saving him!
I hope that he was still able to do something for the orphans, and maybe insist on creating a Hogsmeade Memorial.
