Courtney "Disruptive Influence" Woods, also known as The Nightmare Child, was a student at Coal Hill School under Clara and Danny Osmond. She also served a temporary companion of the Twelfth Doctor, until she suffered the terrible fate of taking part in the episode Kill The Moon.
Courtney's parents look uncannily like what the Joneses must have looked like back when they were together.
Courtney somehow becomes president of the United States, most likely due to the 61st Amendment, also known as the Schwarzenegger Amendment. She also seems to end up hitched to Professor Blinovitch. Who knows.
