|Portrayed by||Josh Brown|
Aiden Keen was a pupil of Waterloo Road in Series Five who had weight problems. Kim Campbell confiscated a bag of doughnuts from him in class after he tried to give some to Sambuca Kelly and Lauren Andrews. His mother brought him some sausage rolls at break time. He was angry that they weren't doughnuts and his mother said she couldn't get into the doughnut shop.
He got into a fight with Lauren in the school canteen just as his mother came in with Kim Campbell and Rachel Mason to talk to him about his accusation of Kim calling him fat after she confiscated the sausage rolls.
