Colin is the attendant at the morgue where Felix and Vic identified Beth's body as Sarah. His first appearance was in the series premiere, "Natural Selection", and his latest appearance was in Season 5.
When they first met, Colin openly flirted with Felix, despite the strange environment, who eventually caught on and invited him to his home in "Conditions of Existence".
In "Guillotines Decide" Felix informs Siobhan that Colin "may come around asking for my hand in marriage."
