i'm still pounding out the details, but peter's a 30something year old doctor (i was thinking maybe a pediatrician, but i'm still deciding on that) or scientist and spends a lot of time in a lab, trying to develop technology that aims to improve quality of life. he's very much the anti the bro that he looks like: he's actually quite soft, gentle, and is a genuinely nice guy, not a Nice Guy. i was thinking he was from some small midwest/southern town and worked his way out through a track and field scholarship to get through school, but definitely has all of this hometown roots and tendencies, though he's lived in boston for a while and isn't total country bumpkin. BASICALLY just a real southern gentleman with a heart of gold, a big passion for making an impact on the world, and is working to prove himself to a lot of people who thought little of him growing up.
