Colin Scott worked for a capital management company and was the boyfriend of Matt Wilding in series 3. He often picked Matt up from school at the end of the day, though Matt was often hesitant to show any signs of their relationship in public, something Colin was frustrated over.
In Series 3 Episode 15 he was angry when Matt moved his stuff out of their flat due to him having not told his mum that he is gay when she unexpectedly came for a visit. On the same day Matt and Steph Haydock were leading a student trip to Colin's company to show them how the business world worked. Maxine Barlow overheard Colin and Matt arguing about him being moved out and sent a text to her friends at school, outing Matt as gay. Although they broke up they reconciled at the end of the episode after Matt found out his mother had known all along about his sexuality. Colin was last seen comforting Matt after his argument with his mother, and Matt proposed to him which he accepted.
In Series 4 it is mentioned that Matt and Colin are no longer together.
