i will never complain about a book seeming like a fanfic with the serial numbers filed off because that means the author had the invaluable ability to tell when their au had diverged enough that these were just straight-up different characters now
even as we speak there is probably someone out there writing a delightful 100k+ word gay romance novel about a genderqueer bisexual single parent who lives in a beach town and fixes classic cars and falls in love with the sexy tentacle monster mermaid that saved their life, and that writer could probably make pretty good money self-publishing it, but they won’t because that would mean admitting that they aren’t really writing destiel anymore
