Testament was the sixteenth short story in the Short Trips anthology Short Trips: The Centenarian. It was written by Stephen Hatcher. It featured the Seventh Doctor.


The Doctor arrives on Earth in 2025 to visit Linda Grainger, but he discovers that everyone on Earth seems to know him. Not only that, but things don't seem to have changed much since the 1990s, and the Doctor wonders where are the innovations that will eventually lead humans to explore beyond their solar system.

He goes to visit Linda, hoping she can explain, but instead he meets with her father John. John explains that there has been no innovation or invention for decades, and when an alien species called the Benanki claimed Earth as part of their empire, humanity was content to welcome them. John says that his father Edward Grainger and the Doctor are to blame: several years ago, Edward wrote his memoirs detailing his experiences with the Doctor, which over time made people complacent — they expected the Doctor to solve all their problems.

The Doctor decides to go back in time and prevent Edward from writing his memoirs. He gets a job as Edward's assistant, and does everything he can to distract Edward, including tampering with his memories so Edward won't remember having met him before.

He finally tells Edward the truth, that he can't publish his memoirs or Earth will be doomed. Edward accepts this and asks the Doctor to take away his memories of his times with the Doctor.

The Doctor has saved Earth's future, but there is always a price: John will not have any future.
