Edith Medina
From Tardis Wiki, the free Doctor Who reference
Captain Edith Medina was the captain of the spacecraft that travelled to Ryklan.
During the journey, officers including Alan Sigraff staged a mutiny against Captain Medina on fabricated grounds. She was imprisoned and visited by the Eleventh Doctor, Amy Pond and Olivia Pamiec, who wondered if she could be responsible for the Calendar Man's killings. The truth was soon discovered.
