Saying that her is a five/ten fic for you, that's quite old but really good.
Title: A Hull of a Time
Rating: All ages
Word count: 1290
Author's summary: The Fifth Doctor, Tegan, and Turlough in Hull in the 1920s. Wonder who they'll meet?
Characters/Pairings: Tegan Jovanka, The Doctor (5th), The TARDIS, Turlough, Kathy NightingaleWarnings: None
Recced because: The unfinished story of Blink is Kathy's marriage, and her simultaneously uplifting and depressing fate is explored in this fic. Added to this is a nice character student of the fifth Doctor, Tegan and Turlough. A lovely, bitter sweet snapshot.. And the ending is fantastic.
