Mike Pratt is Fiona's corporate boss and boyfriend in Season 4. Their relationship developed when Fiona started her internship at World Wide Cup, and had a brief affair during a camping trip, which Fiona declined in concern for her relationship with Steve/Jimmy. They began dating shortly after Jimmy's disappearance. He is good-natured, responsible, and desires trust and honesty, which Fiona enjoys but finds a little tedious over time but they end their relationship after Fiona has an affair with his brother, Robbie. Despite this, Mike bails Fiona out of jail following her arrest for Liam ingesting cocaine having been called by Carl. However, Mike makes it clear he wants nothing more to do with Fiona after this.
