Yeah I associate him with those fandoms too! Also MCU, after that. He was in harry potter first though, and from what I've read of his older fics, he was pretty quippy in those days too; I think it might just be his style as an author. It works better in some contexts than others, I think.

I get so frustrated with SO MANY books about royalty these days! There were different things to be mad about in older books, but it seems like the current approach is just like, "I want the escapist fiction but I know royalty is bad," and then the author tries to split the difference, and I don't know that I've ever seen that done truly well.
