I'm pretty open, but would love if it was someone he grew up with and eventually moved to cali with. He got in a bit of trouble shortly after losing his father when he was a teenager. Basically he fell in with the wrong crowd and starting dabbling in drugs, drinking and partying. He lost his scholarship, which lead him to straighten out a bit. I'd basically love a friend who was there during all that, but also helped keep him from going completely over the edge. They get into all kinds of shenanigans together but have each others backs at the end of the day. they could even be roommates, or at least were when they first moved to the area
