Canon: What actually happened.
Headcanon: What you think happened, based on the characters, settings, storylines and all reasonable extrapolations thereof.
Heartcanon: What you feel ought to have happened, quite divorced from rationality or sense.
Soulcanon: What you know happened, deep down in your soul, regardless of what anyone says. Including the creators of canon, themselves.
Crotchcanon: What your gonads wish had happened, or, alternatively, what turns you on.
Oh my goodness.
They forgot fanon which seems to be confused these days with canon…
So, what is “fanon” then?
//Fanon is stuff not in canon but that’s so prevalent in fandom that people have largely forgotten it’s not in the source material, ie, Daniel Molloy wearing glasses (which is Movieverse Canon, but literally never happens in the books). It’s headcanons that are extremely common or permeate the fandom so deeply it’s hard to separate them from canon, even if they never actually appear in the main material. (I think.. maybe someone else can explain it better.)
“The book never said it /didn’t/ happen” i say as I rub my little fangirl hands together.
