Kieran was born in Manchester, the United Kingdom, the older brother of Cayley Hawthorne. While Kieran's family eventually moved to York he elected to remain in the city, working on earning a law degree at the University of Knightsbridge. With education proving expensive Kieran joined the British Army, serving in the Intelligence Corps before later ending up in the Special Reconnaissance Regiment. Kieran's time with the military helped teach him survival and surveillance skills. For a time Kieran also dated Verity Knight, an officer with the Security Service, or MI5. His promising career came to an end when he was discharged for insubordination. While Kieran managed to avoid a dishonorable discharge he was none the less done with the military, though by then he'd managed to earn a degree in Law.
Back in Manchester, Kieran was hired by the lawfirm of Sutcliff & Raynott. When Cayley started to attend Knightsbridge Kieran kept his distance. He still promised his sister to support her if she desired it, the two also spending time together on the occasion. In July of 2008 Kieran was in a car accident outside the city along with Heather Prescott, resulting in the pair's first meeting. With each blaming the other for the accident their relationship seemed doomed from the start.
A month later, after having met with Heather again, Kieran suddenly discovered time was frozen. Not able to make sense of what was going on, Kieran found himself spending days in frozen time before eventually discovering Heather was also not frozen. The two investigated the scene of their crash and discovered traces of a magical ritual (one performed by Joanne Gallagher on the Winterborne Armband), but still were unable to understand what exactly had transpired. Eventually the pair learned to unfreeze time by holding hands and learned they could both unfreeze it and freeze it at will. Kieran remained cautious about abusing the newfound power but did concede they should try to learn more about it.
