Shaneeqi
From Tardis Wiki, the free Doctor Who reference
Shaneeqi, a human celebrity, was really an Auton made to think she was human in order to aid their invasion. She did not know anything about the Autons until they started to invade. She realised her Husband Paul Kendrick was another Auton like her. She died saving Kate from being crushed by a lift by holding it up in time for Kate to get out. (NSA: Autonomy)
