Ross McNamara was a brief associate of the Twelfth Doctor.
In 2015, Ross went down to his school basement to face the legendary school ghost and impress Dan Hinchliffe. He was locked inside the basement and exposed to chronal vapours from a Helestican spaceship. The vapours sent echoes of Ross through time and briefly transporting him to the year 2115. The Twelfth Doctor suggested Ross might be every ghost ever reported. After exploding Ross's school, the Doctor returned Ross to his home in 2015. (PROSE: Haunted)
