Episode 7 of Mr. & Mrs. Smith begins with Jane and John slumbering in separate chambers, a sign of their fractured union. As John ventures out, Jane stealthily makes her way to the abode of a woman named Bev. While Bev calmly prepares a cup of tea, Jane draws her gun, pointing it at the startled woman. Jane demands to know how long Bev has been involved with her husband. Bev protests innocence, admitting they had met in a bar and shared pleasantries over movies and drinks, but nothing beyond that. However, she confesses to knowing John's secret life as a spy.
John, hearing Bev's revelations, feels a growing sense of entanglement with Jane's world, wondering if they are truly compatible. Despite his doubts, he finds himself longing for Jane, even if their union remains fraught. Suddenly, the doorbell rings, and John arrives unexpectedly. Jane quickly hides, whispering to Bev to conceal her presence.
John enters, pulling out ice cream from the fridge and offering it to Bev. They settle in to watch a movie, but John's curiosity gets the better of him, and he abruptly asks Bev about the whereabouts of his wife. Bev reacts swiftly, leaping to her feet and engaging John in a fierce struggle. Jane, realizing the commotion, rushes in to join the fray, but Bev manages to escape.
It turns out that John had planted a tracker on Bev, and they pursue her to a bustling train station, only to lose her in the crowd. Their pursuit halted by John's dying phone, they engage in a heated argument. Jane reveals that she has uncovered his passwords, accusing him of having had ample time to eliminate Bev. John insists he had a plan, but their dispute only intensifies.
Eventually, they manage to charge John's phone at a nearby store, and the conversation returns to Bev. It transpires that their missions now permit them to engage in intimate relations. Jane accuses John of favoring Bev, pointing out that he kissed her but abstained from sex, which she interprets as a sign of Bev's superior importance. John counters that Bev worked for a rival organization, and their relationship could have yielded valuable insights into the Mr. and Mrs. Smith program.
As John's phone finally powers on, they follow the tracker to Flatbush, discovering that Bev is hiding in an apartment accessible only through a locked white door. They bide their time, waiting for her to emerge, their argument about John's emotional entanglement with Bev simmering in the background. Suddenly, the tracker begins to move, leading them to the theatre where they had embarked on their inaugural mission. It transpires that John had confided in Bev about this pivotal moment. They find a note from Bev taped to the window, the tracker attached to it.
As they head back in a taxi, Jane struggles with the effects of her allergies, her discomfort a tangible reminder of the tumultuous journey they have shared. Upon returning home, John discards the neighbor's soup intended for Jane and prepares a fresh batch himself. He chats amicably with his mother while cooking, a moment of domestic normality amidst the chaos of their secret lives. Finally, he carries the steaming soup upstairs, hoping it will bring some comfort to Jane in the midst of their complex and often tumultuous relationship.
Jane unexpectedly discloses that it was Hihi who instructed her to meddle in John's situation, leaving John astonished. John then recalls that Hihi had informed him that Jane was present at Bev's abode. The question arises: Why would Hihi orchestrate such intricate maneuvers? As John hurriedly texts Hihi, notifying him of Bev's escape, they ominously remark that the Smiths have now suffered three consecutive failures. John, defeated, announces his resignation, informing Jane that he will depart the following morning. Jane, overcome by frustration, violently throws her laptop to the ground in a fit of anger.
A suspenseful mid-credit scene unfolds, revealing a mysterious woman delivering a package to Jane. With trembling hands, Jane unwraps the parcel to discover a sleek, brand-new laptop, marking a surprising twist in the final moments of Episode 7 of Mr. & Mrs. Smith.
