i'd be perfectly fine with keeping what you have for him so far. i don't mind playing married-with-kids characters as long as that's not the only thing they're capable of talking about (which happens so often in rp). the wife and children would likely remain npcs until the end of time, so if they mesh well you're welcome to sock puppet (ha ha) them for narratives or whatever you need.
all that being said, i can imagine he felt ridiculously concerned for puffin when they were growing up. based on what you have in her history she was a real dreamer and the family wasn't sure where the hell she was going to end up. i'm sure as much as he was annoyed at getting punk'd all the fucking time, he was cognizant of the fact he was probably one of the few constant people in her life so...get dat content, lady. i'm thinking he's a pharmacist at a big-box store. when he decided to go to school, his primary concern was finding a job that would be stable, not so much whether or not he'd enjoy himself at work for the next 30+ years.
let's get an ooc custom going to talk further? i have some questions for you and i'd like to be able to keep track of them should we decide to move forward.
