So what's your character been doing up until now? Maybe Falk's dad was just kind of a dick and had lots of sex and had kids on every town? His mom died in a car crash when he was a little over a year old. He has a stable home life right now. Also, how old are you shooting for for your character? Falk and his grandparents are both in the phone book, and his grandma is a very motherly sort, so she'd be happy to adopt Sienna. My brain's a little fried now 'cause I'm running on three hours of sleep, I'll have better ideas tomorrow.
