Dan Hinchliffe

Dan Hinchliffe was a student in 2015. He was the best friend of Ross McNamara until Ross accidentally called his teacher Mrs Latif "Mum." Then Dan laughed at Ross and the other kids began to like Dan. Dan started to become a bully. The Twelfth Doctor later told Ross that someday Dan would realise that he had made a mistake.
