Birthday?
She keeps bringing up his birthday and how its unusual and when does he celebrate it? Is the birthday Feb 29?
"I totally saw his wolf junk"
It's because he doesn't know what it is. He lost his parents when he was four and had no relatives. There's a very brief glimpse of his NM state ID card that lists his DOB as 1978/79, which is how she found out he doesn't know what his birthday is.
He doesn't even know what his first name was.
