Courtney Woods

Courtney Woods was a pupil at Coal Hill School who was taught by Clara Oswald and Danny Pink. (TV: Listen) She was infamously known as a "disruptive influence" and took great pride of her insolence. (TV: The Caretaker)

After being threatened to be kicked out of school by Clara, she replied with, "Go on, do it." Clara was inspired to use the same tactic against the Half-Face Man when he threatened to kill her. (TV: Deep Breath)

She teased the school secretary about Danny. (TV: Into the Dalek)

She once told Clara she couldn't focus on her work because Clara's face was "too wide". Clara related this story to Danny on their first date. (TV: Listen)

Courtney went to fetch some paper towels from the new caretaker - the undercover Twelfth Doctor - and saw a light coming out his TARDIS. He initially denied her knowledge, but then showed her the capabilities of his ship. He took her into space. The experience was too much for Woods, who was made sick by it. (TV: The Caretaker)

Courtney eventually became President of the United States. (TV: Kill the Moon)
