Fetch (Timewyrm: Apocalypse)

Fetch was the Companion of the Grand Matriarch of Kirith. Although the Panjistri usually treated the Companions like slaves, Fetch's mistress came to regard him as a trusted confidante. Fetch in turned cared for her, but grew concerned as the Timewyrm (who had possessed the Grand Matriarch as a child) slowly took over her personality. When she dismissed Fetch from service, he went to the Seventh Doctor for help and led him to his mistress, who killed Fetch for betraying her. (NA: Timewyrm: Apocalypse)
