Pete was an attendant at the Walker General Hospital morgue. Pete and his co-worker, Ted, took in the Seventh Doctor's body after he died during surgery. Later, while Pete watched the 1931 film version of Frankenstein, the Doctor regenerated into his eighth incarnation and burst out of the morgue. This so frightened Pete that he fainted.
Pete was at the hospital's 1999 New Year's Eve costume party being kidded by Ted who, having had his Wild Bill Hickok costume stolen by the Doctor, had dressed instead as a walking corpse. (TV: Doctor Who)
