Jeff was a boy who was possessed by an alien billionaire.

Biography
At the age of six, Jeff was taken to see Isobella Havelstack. On this visit, the mind of billionaire Terrence Malson was transferred into Jeff. At the age of sixteen Malson would be able to take over Jeff's body. However the Eighth Doctor showed Jeff how to erase his mind. This would prolong Jeff's time in control of his body. Jeff eventually had enough of running from Malson's henchmen and shot himself in the head, seemingly killing Malson. (AUDIO: Running Out of Time)
