Marta (The Time of the Doctor)
From Tardis Wiki, the free Doctor Who reference
Marta was an inhabitant of a town called Christmas. She was coupled with Abramal. She told the Eleventh Doctor and Clara Oswald about the Truth Field.
When asked by the Doctor if the truth field made things difficult, Marta said "Not at all", the same time as Abramal said, "Yes." (TV: The Time of the Doctor)
