Oswin Oswald's mother
From Tardis Wiki, the free Doctor Who reference
Oswin Oswald (who was a version of Clara Oswald) had a mother. It was her birthday the day Oswin got converted into a Dalek however she created a dream for herself so she didn't have to face the truth. Exactly a year later, in her dream she made a souffle for her however she burnt it. This birthday was also the day that Oswin met the Doctor, Amy, and Rory and the day she realised she was a Dalek. Nevertheless she helped them escape the Dalek Asylum destroying herself in the process. (TV: Asylum of the Daleks)
