Johnny Hitchley's mum
From Tardis Wiki, the free Doctor Who reference
A Zygon took the form of Johnny Hitchley's mother.
In Turmezistan, Hitchley ordered the Zygons hiding out in a church to show themselves. Instead, a Zygon emerged in the form of his mother. Colonel Walsh ordered Hitchley to kill her, but Hitchley instead asked her personal questions, such as his date of birth and favourite teddy bear as a child. She was unable to answer, but mentally called out Zygons disguised as the loved ones of the other soldiers. Hitchley loved his mother so much that he eventually brought his soldiers inside. Inside, the Zygons killed them. (TV: The Zygon Invasion)
