Season overview
Immediately after Fiona is arrested by the FBI, she is processed and taken into an interrogation room, where she is interrogated by Agent Jason Bly (Alex Carter), who is on loan from the CSS. Bly tries to get Fiona to implicate Michael in the British Consulate bombing, but she refuses to cooperate. Meanwhile, Michael and Sam pursue Anson Fullerton (Jere Burns) throughout Miami and corner him in a chemical plant, with eventual help from Agent Dani Pearce (Lauren Stamile). Anson does everything he can to stop Michael from pursuing him, even going as far as sending a former patient of his to Madeline's house. Michael brutally attacks Anson upon finding him, but is forced to let him escape after learning that he wired the building to explode. After warning Sam and Pearce, they make it out of the building when it explodes. Michael tries to shoot at Anson, but is furious that he got away. Pearce informs Michael that Anson just hit the top of the CIA's most wanted list, but all they can prove is that Anson tried to blow up her extraction team.
After Fiona is taken to a federal prison, she becomes marked for death and is targeted by inmates, but she makes an ally named Ayn in prison. Michael visits his former training officer, Tom Card (John C. McGinley) for help getting visitation rights to see Fiona, but Card initially denies his request. However, after Michael, Sam, and Jesse help Card take down a drug cartel, Card agrees to pull strings to grant him visitation rights. Michael also learns from his brother, Nate Westen (Seth Peterson) that Ruth left him and took their son with her, so Michael invites him to stay. The team help Pearce track down the man who killed her fiancée, who is currently a protected CIA asset, and trick him into giving up the intel the CIA needs in order to remove his protection.
Michael visits Fiona and promises to get her out, and they reminisce over their time in Belfast. Afterwards, Michael receives a note from Fiona, learning that someone is trying to kill her and is working with a dirty guard. Michael, Sam, and Jesse pay the guard a visit in the Everglades, only to find him dead. Sam is then kidnapped by former CIA operative-turned-traitor, Rebecca Lang (Kristanna Loken), so Michael and Jesse work to rescue him. However, upon learning that Rebecca is being blackmailed by Anson, who is threatening to have her brother killed, they offer to help her save him. As the team works to save Rebecca's brother, Michael also simultaneously works with Card to take down one of Fiona's weapons dealer in exchange for her release from prison. Both plans work, so Fiona becomes a CIA asset and Rebecca provides Michael with Anson's location where he's expecting his latest drop of travel documents and cash. After Michael tells Fiona that they found Anson, he informs her that she has to plead guilty to a few weapons charges and her sentence will be time served. Her release is put in jeopardy, however, when an MI6 agent tells her to either accompany him to their new British consulate or sign a new confession. His plan fails, however, when Fiona disappears for a little while and has Ayn find her.
Michael, Nate, and Jesse join Pearce and her extraction team in Atlantic City, but Michael gets angry at Nate for nearly jeopardizing their op twice, forcing him to leave. However, upon learning Anson's location and realizing that Nate is closer than they are, Michael has Nate keep eyes on Anson but warns him not to approach him. Nate, however, punches Anson and captures him, bringing him outside at gunpoint. Just when Michael and Pearce are about to arrest Anson, a mysterious sniper shoots Anson and Nate, killing them both. A heartbroken Michael breaks the news to Madeline, who does not take it well. Fiona is finally released from prison into Michael's arms, with Michael telling her he needs her more than ever.
