Biography
Paterson followed the Doctor after receiving neighbourhood watch complaints of his antics (in attempting to lure a kitling), but while trying to apprehend him, they both were teleported to the Cheetah World.

He escaped from the world, being teleported back to Earth by Ace, but passed the experience off as a stress related hallucination when he returned to the youth club and his students. Unfortunately they had been hypnotised by the Master. They killed him after goading by a possessed Midge. (TV: Survival)
