Old Friend (comic story)

Summary
The Tenth Doctor and Emily exit the TARDIS, which has appeared next to a house for the elderly. Entering, they are met with suspicions by the head nurse, and claim to come as a "surprise inspection". In the house's main hall, a small party is being thrown for Barnaby Edwards, one of the residents, who all of a sudden recognizes the Doctor and asks to talk to him.

Barnaby tells him of how he recognized him, in spite of being a companion of a future Doctor, and how this Doctor gave him an envelope to hand to his previous self. He also mentions previous (from his perspective) encounters with Sontarans and "the Floor Menace", and profusely apologized for leaving the TARDIS, explaining how he had fallen in love and felt he had to live his own life.

Allaying his fears, the Doctor assured him he had been "one of the best companions ever" and that he did not nurse any anger towards him for leaving the TARDIS. The relieved Barnaby sighed in relief and went to sleep as the Doctor left. Emily tried to tell the Doctor something about Barnaby, but the Doctor stopped her, telling her he didn't want to know.

Opening the envelope within the TARDIS, the Doctor found a single, charred sheet of paper-one of the pages of the false diary supposedly kept by Turlough. Realizing the message was that the diary was to be soon destroyed, the Doctor changed course to meet with the Advocate and ensure her final defeat.
