The Doctor commits suicide and regenerates into a female form. She then departs for Earth and begins a mundane life of working all day in a supermarket and spending all night in the pub. Her previous form haunts her, trying to remind her who she is and not to give up. Meanwhile two other Time Lords have been sent to find and arrest the Doctor.
David Tennant, who features in a supporting role as "Time Lord 2", was formerly Arabella Weir's lodger and is godfather to one of her children. He later went on to star as the Tenth Doctor in the television series.
When the Previous Doctor lists various names for the Master to use as aliases, he says the name Eric, then Robert then Sam in quick succession, forming the name 'Eric Roberts' a reference to the actor of the same name who portrayed the Master in the 1996 TV Movie.
The robotic scarecrows used by the Time Lords to hunt down the Doctor are a reference to the 1969 TV Comic story The Night Walkers. In this comic, the Second Doctor also escapes at the end of The War Games and hides on Earth, only to be captured by the Time Lords' scarecrows and forced to regenerate.
