John Hancock always gives me the vibe of someone who tries to act very cool, but in reality, he's a bit of a loser with low self-esteem problems (affecionate).
I don't mind him being portrayed as some kind of hot guy but I have a different view about him in my headcanons:
he's the type who would secretly sob if someone compliments him/ expresses affection (he wouldn't understand why since he still sees himself as a terrible person)
Honestly? Touch starved. I imagine him as one who had his flings but is not used to constant love/affection from someone. He would want it, but at the same time, he feels like he doesn't deserve it.
Despite that, John is very affecionate and cares a lot for the others. Mostly, he gives hugs.
Also, definitely, the guy who moves in his sleep and wants to stay close to you as much as he can.
likes reading books, especially history-related ones (He would casually drop facts when he's high or during small talks before sleeping). My man in the post-war era referenced Napoleon. I don't think it is common knowledge in the wastelands.
Related to the previous headcanon: I think John would be curious about pre-War politics or at least the culture.
He uses his more bad and corny jokes when he's high, or he's genuinely interested romantically in a person, nothing in between.
Sometimes, he gets hurt by doing the knife trick. Usually small cuts, nothing too serious.
