Persistence is another thing that really confuses me about the term. Like is 'a headcanon' a one-off, possible idea, or something you believe to the extent you hold no contradictory views, or just like, a thought? People can have personal decisions on that, but it's weird bc person to person, I don't know how they're using the word.

And what about the sort of collective nature of fanon, where everyone as a group decides Avon's gonna have back pain because Cally said something to that effect one time? That absolutely still happens, but we don't talk about it that much rn.
