Referencing a character in a wildly popular, successful, and entertaining young adult book series doesn’t mean someone hasn’t moved on. I haven’t read any of the books since the last one came out and have read many other books that imo are far better. It’s still a great reference.

If you don’t like it, don’t read it. No need to be a gatekeeping twat about out it though. Just keep scroll and ‘move on’.
