Angie discovered photographs of Clara Oswald on the Firebird in 1983 and at Caliburn House in 1974, and a photograph of Clara Oswin Oswald in Victorian London. She and her brother used these photos to confront Clara after she got home from Victorian Yorkshire and deduced that Clara was a time traveller. Angie threatened to tell her father about Clara's secret unless Clara agreed to take them on a trip with her. (TV: The Crimson Horror)
The Eleventh Doctor took Clara, Artie and Angie to Hedgewick's World of Wonders. After riding the Spacey Zoomer Ride, Angie got bored and wandered off to the punishment platoon barracks. There, a Cyberman arrived and kidnapped her. Put into a walking coma and not fully upgraded, she was finally released when Mr Clever freed her and her brother once the Doctor sacrificed a chess piece in their game for control of the Doctor's mind. Clever threatened to have Webley kill them, but Emperor Ludens Nimrod Kendrick Cord Longstaff XLI used a hand pulse to deactivate him. After the Cybermen were defeated, the Doctor returned Clara, Artie and Angie home. (TV: Nightmare in Silver)
Back in London, Clara prepared to make another of her mum's soufflés for Angie and Artie, to Angie's displeasure. Angie told Clara she had a letter sent to her. The letter held a soporific which caused Clara to fall asleep. Later, when George left the house, the Doctor agreed to take care of Angie and Artie, denying their requests to go to the cinema and insisting they wait until Clara woke back up. They then tricked the Doctor into playing blind man's buff, which Clara realised after waking up was a ruse to get to the cinema. (TV: The Name of the Doctor)
Angie felt very strongly and often said that Clara was not her mother and that she was "stupid". She and her brother also thought the Eleventh Doctor was Clara's boyfriend. She was very observant, figuring out that Porridge was an Emperor before the Doctor did. (TV: Nightmare in Silver)
