Rex Matheson

Rex Matheson was a CIA agent in the 21st century.

Biography
Matheson was talking with his colleague Esther Drummond on the phone when he was involved in a car crash, a pole from a nearby truck pierced his body.

Matheson later awoke in a hospital and learnt that the pole should have killed him and began to look into Miracle Day, a phenomenon where no human on Earth could die.

Matheson's hunt for answers led him to Wales, where he sought out Gwen Cooper, a known member of the Torchwood Institute. Upon finding her, he collapsed due to his injuries and was taken as her prisoner.

Matheson freed himself and escaped with her, Rhys Williams and Jack Harkness as they were pursued by an armed helicopter. Following this he informed the police of the teams whereabouts and had them extradited to America. (TW: The New World)
