Episode 8 of "Mr. & Mrs. Smith" opens with Jane waking up alone in the quiet house, her morning routine a stark contrast to the drama that awaits. She flips open her laptop, her face tense as she reads Hi's chilling new order: 'Take out your Smith'. With a determined nod, she heads out for breakfast, returning home to the familiar sights and sounds of her life with Max.
As Jane feeds Max in the kitchen, the tranquility is suddenly shattered by gunfire. She ducks behind the kitchen counter, her heart pounding, but it's too late for Max. The innocent creature lies wounded, and Jane's world shatters.
Meanwhile, John walks alongside his mother, their steps echoing in the quiet street. Their homecoming is interrupted by John's sharp observation: the toilet seat in the nearest bathroom is raised, a sign of something amiss. He alerts his mother, Denise, urging her to leave for the salon while he investigates. His suspicions are confirmed when he discovers a trip wire by the front door. He messages Jane, and the two agree to meet and talk.
Their rendezvous takes place at an art museum, the serene atmosphere a stark contrast to the danger that surrounds them. Each assumes the other is responsible for the attacks, their trust shattered by the events of the morning. Jane suggests they speak outside, but as they exit, she drops a knife, jamming the revolving door and trapping John inside. Inside her bag, he discovers an explosive, which detonates, sending shrapnel flying. John manages to escape the blast, but the narrow escape only fuels his anger.
He chases Jane through the museum, their fight spilling into the public eye. Jane is finally pulled off John, but the battle isn't over. They are now faced with a new threat: the men who have been stalking them. The police arrive, but John creates a distraction, allowing them to escape through the chaos.
Later, John calls Jane, his voice soft yet determined. He tells her that when he first saw her in the elevator at their house, he thought she was the most beautiful, lonely girl he'd ever met. He wants to know if any of their relationship was real for her, but she denies it, her voice cold and distant.
Across the street, their eyes meet, and the chase begins again. Jane runs home, her heart pounding, and locks the front door. But Denise is waiting for her inside, her face a mix of sorrow and resolve. She reveals that she is Michael's mother and possesses an emergency key. Outside, John meets their neighbour and asks if he can use his house to reach the backdoor.
Inside, Denise tries to reach Jane, her voice gentle yet firm. She tells Jane that if Michael feels safe, he will be able to truly be himself. But Jane pushes her away, her walls too high, her heart too guarded. And as the episode ends, the tension mounts, leaving the audience on the edge of their seats, eager to see what will happen next.
At the neighbor's abode, John suddenly realized that he had previously entered the premises to deliver a book to Jane. Curious, he snooped around the house and stumbled upon photos depicting himself and Jane together. Suddenly, a man caught him red-handed. John quickly drew his gun and pointed it at him. The man introduced himself as Harris, claiming to be a real estate agent. Harris revealed that he had been eyeing their house, believing it was too luxurious and beyond the Smiths' financial reach. However, John eventually lowered his guard, deeming Harris harmless. Instead, they engaged in a candid conversation about relationships and divorce.
After finishing his drink, John quietly returned to his and Jane's apartment. He crept through the rooms cautiously, but Jane suddenly emerged and fired at him. The clash escalated, with both parties brandishing guns and knives in a deadly dance. In the end, John managed to knock Jane unconscious and tied her up. Desperate to uncover the truth, he injected both her and himself with the truth serum they had used in Episode 2. As the serum took effect, they both felt woozy.
Jane revealed that the CIA had suspected her of sociopathic tendencies. She confessed that her father had never wanted to know her. John, in turn, admitted that he was ashamed of his asthma. Jane surprised him by revealing that she had never slept with her targets; she had only lied to hurt him. John confessed that he desired children above all else. They revealed that, despite having clear shots of each other during their fight, they had chosen not to pull the trigger.
Amidst their laughter and tender kisses, they realized that they hadn't attacked each other during their first encounter. It had been someone else. Suddenly, Another John and Another Jane stormed into the house. They revealed that their sole purpose was to eliminate other Smiths. The man the Smiths had killed in El Salvador was also a Smith. They spoke reverently about Hihi, as if he were a deity, revealing that he had known John's intention to visit the juice stand before John himself was aware. It had all been a setup.
As Other John sneezed, our Smiths seized the opportunity to make their escape. Other John was hit in the eye, but the Smiths managed to reach their elevator and scramble into the house's panic room. Inside, Jane realized that John had been hit by a bullet. Worse still, they only had one bullet left. Other Jane stood ominously outside the door of the panic room. As John's life slowly ebbed away, Jane proposed that they could have one child. John, in a bid to keep him conscious, coaxed her to negotiate for two. John's consciousness was fading rapidly.
Outside, Other Jane persisted in trying to enter the correct passcode to access the room. Jane made a decision; she would open the door and attempt to shoot Other Jane. She counted to three, and a flash of gunfire illuminated the house through the window.
In a mid-credit scene from Mr. & Mrs. Smith Episode 8, we see Harris, the neighbor, approaching their house once again, presumably to deliver a book to Jane. He finds the house in disarray and calls his colleague, suggesting that the property will likely be ready for sale soon.
