Yes, I have been feeling some of the same things. I have been tempted to orchestrate a campaign of "search and replace" through my existing fics to change 'Theodore' to 'Edward,' for example. It's strange to have the creator still out there, generating new material.

But I second alias_amy's suggestion that canon is the seven books. It's nice to know what Rowling thinks some of these details are. But I cried (a bunch) reading Kaleidoscope; I didn't cry reading the Lupin bio. I continue to find your version important and beautiful and stirring. Don't stop.

If anything, I was struck by how much Kaleidoscope is in line with Rowling's ideas. It made me think, huh, you've intuited a lot about these characters from details she provided. And that's cool.
