Nova Osgood
From Tardis Wiki, the free Doctor Who reference
Nova Osgood was the sister of Petronella and daughter of Frank Osgood.
Osgood was jealous of Nova, who got away with anything (PROSE: For the Girl Who Has Everything) and was, she believed, prettier than her. (TV: The Day of the Doctor) Nova always left her Christmas shopping until the last minute and, in 2011, simply put her name on Osgood's present for their father. (PROSE: For the Girl Who Has Everything)
In 2013, a Zygon that copied Osgood's appearance mocked her, saying that she should have copied her prettier sister. (TV: The Day of the Doctor)
