In the sixth episode of Prime Video's "Mr. & Mrs. Smith," titled "Couples Therapy (Naked & Afraid)," John and Jane Smith confront the deepening issues in their relationship through the lens of couples therapy, led by therapist Sarah Paulson. This episode delves into the emotional complexities of their lives as spies and the impact it has on their partnership, both professional and personal.

The episode begins with John and Jane in the therapist's home, pretending to be software engineers to explain their high-stress lifestyle. John initiates the conversation by suggesting that their boss, Hihi, favors him, a claim Jane refutes. The discussion quickly shifts to their differing desires for children and the challenges of living and working together. John feels controlled by Jane, a sentiment he illustrates with a recent mission they undertook.
We flashback to John and Jane on a rooftop, surveilling an apartment. John requests to lead the mission to prove himself to Hihi. The mission involves infiltrating a poker game with their target, where John's behavior raises Jane's concerns about his sexist and racist comments.
The poker game takes a deadly turn when two players are executed, and John is forced to confront the remaining target. Jane, listening over the comms, criticizes John for his slow response, while John argues that Jane's aggressive handling of the situation almost got him killed.
A week later, the couple returns to therapy. Jane admits that things haven't improved, and the therapist notes that Jane often speaks for both. They discuss a recent foot chase where John, hampered by asthma, failed to keep up. The argument escalates to Jane's constant need to "fix" John's mistakes.
The episode cuts to Jane and the target in a dramatic elevator fight, while John struggles to climb the stairs. Jane's victory is overshadowed by John's laughter, which he claims is a response to her catchphrase during the fight.
The therapy sessions continue with the couple discussing a failed camping trip mission. The disagreement centers around a book, "The Prophet," which Jane loves, and John has lied about reading. This revelation sparks a heated argument about their emotional disconnect and John's relationship with his mother.
The therapist suggests that John and Jane take a break from working together, an idea they both agree to explore. Before leaving, the therapist gives them a thumb drive with recordings of their sessions, revealing her hidden cameras and microphones.
The episode concludes with John and Jane fleeing the therapist's house after a fire is reported by her son. The couple decides that therapy is not for them, ending the session on a note of discord and uncertainty about their future.
"Couples Therapy (Naked & Afraid)" is a pivotal episode that exposes the raw nerves and deep-seated issues within John and Jane's relationship. It masterfully weaves together the couple's emotional struggles with their spy missions, providing a nuanced look into how their dangerous lives affect their ability to connect and trust each other.
