It's been a while since you wrote some nonbinary Hannibal headcanons--I would love to hear more if you have anything to share! (Sorry this is kinda vague lol)
Oh man don’t apologize!!! Since it’s TDOV I feel this is an especially appropriate time for an ask like this
He and Will have a conversation about it fairly early on (like season one time) where he doesn’t really explicitly say he’s nonbinary but does say some things: Will notices him react sort of oddly to someone calling him a man, and brings it up, and Hannibal says something noncommittal but honest that Will doesn’t question (bc yk he’s just as allergic to clarity as Hannibal is) and his basic takeaway is that Hannibal is weird about some gender-related things but not particularly inclined to correct people about them
It makes Will pay more attention to Hannibal’s microreactions when people use gendered terms on him, and it makes Will more conscious about his own use of gendered terms for Hannibal—although of course knowing Will most of that is subconscious. He doesn’t really Think much about it after the initial conversation but with the way he reads people and mirrors them he just stops using gendered terms for Hannibal basically at all
Hannibal corrects him on that a couple of times during s2 stuff: when they talk about Mischa, for example, Will says sibling and Hannibal says brother. And after that when they talk about Abigail Hannibal talks about having been her mother, and Will doesn’t question him about it bc he can’t engage with that in that context but he knows it’s another important piece of himself that Hannibal gave him, a piece he’s never given to anyone else. Another thing to feel betrayed about when he discovers Will was plotting against him
It doesn’t really come up again until they’re living together post fall and Hannibal really gets the chance to notice how far out of his way Will is going to always use gender-neutral language for him: he starts correcting Will about preferred terms more often, and as it becomes clear that Will is eager to respect that Hannibal starts to feel properly comfortable in his gender for the first time
And Will isn’t super sure about bringing it up himself, but at some point he comes across an nb person who uses alternate pronouns and he asks Hannibal if there are other pronouns he’d prefer, which prompts them to have an actual conversation about it: Hannibal is feeling v safe about it in a way he never has before, and it gives him a chance to verbalize a lot of gender-related thoughts he’s been having for years but had resigned himself to never saying to anyone
After that it’s even better, because he can just talk about it? He doesn’t have to be worried that Will will be bothered or put off by the fact that sometimes certain words feel good in certain contexts and not others, or when he changes his mind about preferred terminology. And Will feels much better about it too, bc he understands the things better and he’s been given permission to try out some terms he’d assumed were off limits
The first time he calls Hannibal his girl in a tender moment he thinks he’s fucked up terribly bc Hannibal’s face immediately crumples with tears, but then Hannibal is clinging to him desperately and he realizes the tears were bc it hit so unexpectedly well
