When Kris first appears in the freshman class with Zoe Carpenter (Zoe Lister) and Will Hackett (Oliver Farnworth). He got into clashes with Joe from his first few scenes. He was also involved in the Dog fire in which Sam Owen (Lois Tammone) sets set alight, in which his friends Olivia Johnson (Rochelle Gadd) and Joe Spencer (Matt Milburn) die. In later episodes Kris thinks he has HIV after Will Hack fools him into believing that his test results were positive. Later Kris started having sex with a guy called Nathan, but when his brother Malachy comes to Hollyoaks, he pretends Nathan is a friend and starts wearing masculine clothes, as Malachy doesn't know that he is bisexual or that he likes to wear women's clothes. Jessica tries to persuade him to dress up for Malachy but when he does, his brother disowns him. He takes comfort with Jess and they end up in bed together. Kris later leaves and returns a number of months later. Malachy also returns later to work on a construction job. While they still don't not agree on most topics, Malachy grows to accept his brother, and when Malachy leaves in January 2008, Kris is somewhat sad to see him go.
