I feel so honored to get this ask becuase im just all in my feels and hyperfixation right now and not by any means an actual fallout blog so here's these few headcanons that I threw together from my personal fics. If anything is confusing, let me know and I'll explain it better 😅

• In his line "Hey. Rads over here. Not for the softskinned", he says softskinned instead of anything like "smoothskin" becuase its, well, a slur in the context some ghouls say it, and also because he is consittered a new age ghoul and doesn't see the need to use such a word to describe someone if it has such negativity attached to it. Especially since it's only been a decade or so since he's been a ghoul.

• Because of his friendship with MacCready and hearing Mac's second hand stories from his Vault 101 friend back in the capital wasteland, he knows all too well of Vault-Tecs experiments in the different vaults. So when he meets the Sole Survivor and finds out what happened to them, he has even more of a reason to hate the company, a personal reason even.

• He LOVES pda in front of people like Pre-BB Danse, X6-88, etc, just to watch them squirm.

• You can pry this from my cold, dead hands, but you can still see a glimer of his concept art blue eyes under the blacked out part from a specific angle in specific lighting. He doesn't notice it until someone who he trusts enough to get that close tells him. He gets a bit warm and fuzzy but doesn't know why.

• (I read that Fahrenheit isn't his daughter in Canon, just in coding terms, so imma run with it) Even though Fahrenheit isn't his daughter he treats her as such. They met when she was young and he took care of her, basically saving her life. So out of loyalty and to repay a debt he constantly tells her doesn't exist, she took up the job of body guard. That and he taught her to play chess as a kid to get her mind off of bad things and that's why when she first meets Sole, she constantly makes chess references.

• He hates the irony that his new identity first name is also John. As much as he wants to forget his old life and name, it's still a bigger annoyance in his mind than he'd like.

• Becuase of being a ghoul, he's a lot warmer than youd think. So much so, sometimes sleeping in a settlement that has cats, he would wake up with one or more on his chest asleep with him.

• He used to hang out in the dinner above Diamond City, the one you have to parkour up to in-game, and do chems in secret away from everyone.

• (This may be something from my personal game becuase as soon as I sent him to a settlement, he started farming without me telling him to do so) He would work at the farm in Diamond city to get money for his chems.

• Loves loves loves leading people on when they think he's an older ghoul and ask what life was like prior to the bombs. "I'm telling you man, deathclaws used to be tiny. Teenage boys would keep them as pets. Feed 'em those little fish from the can. Their bites? Wouldn't even pierce the skin!"

• Even though he "gets around", he is so very touch starved. Like a close friend or significant other hugging him, touching his hands, straightening his clothes, even stealing his hat, he just melts on the inside.
