In "Job", Jack and Victor give him a clean up for a job interview, which he gets at Glasgow City Chambers. However in the following episode "Small Change", he is once again jobless. He was once seen with rotting teeth but in "Job", he acquired a set of false teeth that he unknowingly claimed from a home dentist and since then, is now always seen with them. In series 8, although in each episode, his role was restricted to one short scene or line in most episodes.

In the series 8 episode "The Fall Guy", Mick revealed that, when he was eight years old, his father drowned after falling into a canal whilst drunk.

At the end of the episode "Over the Hill", Mick is shown to be working at Craiglang's library.
