Nurse (Children of Earth: Day One)
From Tardis Wiki, the free Doctor Who reference
This Nurse worked at Digby York Hospital in East Grinstead. She called the attention of the hospital staff when the psychiatric patient "Timothy White" began saying "We are coming" along with Earth's children. When Gwen Cooper came to investigate, she explained to her about his long history in care. (TV: Children of Earth: Day One)
