Caleb is a runner and member of Noah's Cabal.
During Mirror's Edge: Exordium, Caleb is seen hanging around with Faith and the other runners in Noah's Cabal. He was first seen doing a datagrab mission with the other runners while Faith acted as a distraction.
He later appeared in a race against Faith and Celeste. During the race, he slipped and fell due to his "crap shoes". If it wasn't for Celeste, Caleb might of fallen to his death.
