In season 2, Fiona tried to distance herself from Michael after she realized that he was making her his second priority, behind his desire to discover who "burned" him. She becomes involved in a frivolous relationship with a paramedic named Campbell, which caused Michael some slight twinges of jealousy...though not as much as Fiona would have liked. At this time, Michael began to stop taking her for granted as much; and they experience some very emotionally charged moments. Campbell ends their relationship then informs her that Michael was her "real boyfriend". Fiona is also introduced to Samantha Kees, a professional thief and Michael former-fiancée: they got engaged before Michaels mission to Ireland. Michael admits that whilst He and Samantha were similar in personality (hence the ease of their relationship), he was much more involved in his relationship with Fiona, simply saying that Fiona "knew a part of me that never did.", and that Michael ended their engagement because he was in love with Fiona. Soon thereafter, Michael becomes half-crazed with panic and grief after believing that Fiona died in a house fire while investigating a lead for him. He arrived back at his apartment to find Fiona alive and well. His relief at seeing her unharmed is so great that he embraces her and kisses her.
