I see it a conflict in writing Martin as his own character vs writing him as Jon's boyfriend. if he is Jon's anchor/humanity etc etc then you can't really focus on him having lost his own. it would be interesting for them to navigate that together, as a couple, with them both remembering the other as a human when they themselves don't remember (tho that does feel less impactful already solely because they didn't actually know each other when Jon was fully human but I digress). but this is not exactly the route they went with, choosing to give Martin the moral high ground in almost every situation. Jon is the monster. Martin is the human. but all that it does is ignores Martin's arc in s4. I feel like they wrote themselves in the corner by making it a little too similar to what Jon has. they want him to be The Human character (which let's be real, that's Basira) but also an avatar, giving him his own domain and all. and I don't think it works the way they wanted it to work
