Chris meets Anton, a teaching assistant and trance DJ with a deep love of Middlesbrough FC, and Ethan, a 19-year-old student and aspiring rapper from Essex. He helps them make films to reveal to their friends and classmates how Anton feels about change and Ethan about hypersensitivity to noise.
Chris also meets Dr Luke Beardon, an expert in autistic hypersensitivity, and Dr Punit Shah, who helps him to understand both Anton's restrictive and repetitive behaviours and Chris's own need for order in his life.
