Jacob and Theresa Parker had a kid at a young age, 18, to be exact. He was born in a first class Erudite hospital. Since little he was surrounded by technology, which he liked, although, later on, he noticed that he had more PDA's than actual friends.
He started to get along with the Dauntless at school, but he didn't quite like that faction. HE wanted fun... Not a short-limit life span. So he had a Fervor friend, who he really liked to be around with, as a typical fervor, he was very fun and never repeated the same joke.
As fervors, they though that the uprising started because people didn't have enough fun. When Quinn grew older, he was taught how to surf by Killian, his Fervor friend. When the Aptitude Test came, he needed to show what would he do with his life.
