He is asthmatic. I can't explain it but I am convinced he is asthmatic. Butch has always been spotty taking his daily inhaler, mostly as he tried to hide it from the other kids to keep looking tough, and also because he had a bit of an ego.

Even if he was alone he didn't like having to be dependant on the medication, no matter how many times James explains to him he isn't defined by his medical conditions.

That and I just think it's really funny if between bouts of being an outright bully he had to steal away to take a few frantic huffs of his inhaler.

His asthma is the ONLY thing protecting him from being a Lynx Africa user. It is FIGHTING for him.

Butch Deloria is the son of one of the guards. No one knows which guard. Even his mother doesn't know. She got around with them in part exchange for the guards turning a blind eye to her blatant vices and attitude.

He's a wonderful cook after leaving vault 101. It's when he actually gets to learn and despite gagging at some of the ingredients LW collects: he can make some genuinely good food.

Butch is a very restless sleeper. He doesn't struggle to get to sleep, he knows he needs it, but he struggles to stay asleep. He's used to his mother's... moods and having to move or get scarce in the face of them.

Butch is very touchy. Beyond just always being ready to get in a scrap. He likes to do hair, he likes hugs, he likes throwing his arms around the other tunnel snakes even if they sneer and shove him off. It makes him feel less alone.

He's a big preener. If he gets in a scrape the first thing he complains about (after he's done assuring the LW he is fine and was fine and he didn't need to be saved (with an occasionally cracking voice)) is that the scar on his face will be ugly.

The open sky freaks him out. I think in canon he is agoraphobic, so I think looking up and just knowing he is staring into infinity unsettles him deeply.
