Episode 5 of "The Perfect Couple" kicks off with Amelia frantically navigating her way to avoid the Winburys' clutches, eager to flee Nantucket's shores as soon as possible. However, fate throws a curveball in the form of Greer's book launch, an event she adamantly insists Amelia attend, lest whispers of infidelity with Benji escalate into a full-blown scandal.
As for Tag, he finds himself trapped within the confines of the police station, with officers relentlessly closing in on him. He maintains his innocence, emphasizing that he's merely a witness striving to unravel the truth. He divulges his affair with Merritt but claims she pushed for more than he was willing to give, prompting him to distance himself. Should they dare accuse him falsely, he vows to unleash the wrath of his attorney.
Flashing back to the rehearsal dinner, Merritt's revelation of pregnancy sends shockwaves through the air, only to be soothed by Tag's elation and a tender kiss. Their love for each other overflows in heartfelt declarations, painting a picture of a passionate entanglement.
In the present, Amelia stumbles upon Abby meticulously packing Merritt's belongings, the weight of loss evident in her words. Abby confesses the rarity of her bond with Amelia and Merritt, offering to stand by Amelia's side like a loyal wingwoman at Greer's launch.
At the glitzy event, Greer's team scrambles to manage the aftermath of Tag's absence, while Will gathers the courage to ask Chloe out, only to lose it in the face of perceived rejection. Abby's musings on Shooter's wealth inadvertently strike a chord of betrayal in Amelia's heart. Benji, on the other hand, drowns his sorrows in alcohol with Isabel.
Meanwhile, the police's relentless pursuit of Tag intensifies, their suspicions fixed on him as the culprit who drugged and subsequently ended Merritt's life around the wee hours of the morning. Tag remains tight-lipped, his mind drifting back to that fateful night. The late-night camaraderie—Tag, Roger, the videographer, Merritt, and Isabel—blurs into a hazy memory as he recalls Gosia watching him hand Merritt his jacket, an innocent gesture that now seems to carry a sinister undertone.
Later that day, as Merritt stumbles upon Tag preparing to embark on a sea journey aboard his canoe, she delicately broaches the subject of their relationship. However, he abruptly shifts gears, pleading for more time to sort through his entanglement with Greer. The realization dawns on Merritt that he is irrevocably tethered to Greer, leaving her devastated. Convinced that he desires her to terminate their unborn child, she plunges into a desperate act of self-destruction, attempting to drown herself in the depths. Tag, in a frantic effort to save her, grapples with her in the turbulent waters.
Amidst the chaos, Tag's gaze falls upon his smartwatch, and with it, he confesses the truth. He recounts their quarrel but produces undeniable evidence—his smartwatch's sleep tracking, proving his innocence as he lay abed while Merritt was viciously drugged and met her tragic end at dawn's early light, around 6 AM.
At the launch event, Isabel offers Amelia her condolences, sharing intimate details of her final conversation with Merritt. Following Tag's heroic rescue, Merritt flees the scene, encountering Isabel in her emotional turmoil. The two women drown their sorrows in alcohol, with Isabel offering sage advice, asserting that the man in question never departs; it's the wife who must be convinced to leave. In a drunken haze, Isabel shatters a glass upon departure, leaving Merritt to hobble away, her foot punctured by the jagged fragments.
Back at the launch, Shooter attempts to mend fences with Benji, only to receive a punch in the face. Amelia, aghast, escorts Benji to the kitchen, attempting to soothe his inebriated ramblings about his feelings for her and their fleeting encounter.
As the launch festivities commence outside, Chloe pens a heartfelt note for Will, admiring his charm. Tag, now a free man but still under the influence, lurks on the fringes. Broderick too arrives, only to be escorted away by security as he lunges towards Greer. Seizing the moment, Tag joins Greer on stage, unexpectedly hijacking the proceedings.
With bold honesty, he exposes their flaws and Greer's attempt to falsely accuse him of murder. As he embarks on a soul-baring song, Greer, fraught with frustration, ultimately surrenders and joins him in the performance. Yet, as Tag stumbles and is escorted away, Greer stands watching, the audience left in stunned silence, witnessing the unraveling of a complex web of deceit and longing.
Meanwhile, the police officers make a startling discovery: the watch meticulously tracks Greer's sleep patterns, even as she shares the same bed with Tag. On the fateful night of the murder, a glaring omission emerges—she was absent from the bedroom between 3 and 4:30 AM.
Amelia confronts Shooter in the aftermath of the disastrous launch, her emotions frayed. She's enraged that he deceived her into believing they were equals, both struggling financially. Yet, she dismisses the matter, proclaiming that she's just as flawed and confesses to her fleeting encounter with Benji.
Greer, seeking solace in alcohol, finds herself at the bar, where Carter joins her. Determined to distract herself from the failed launch, she offers to assist him in unraveling the suspects' motives. Carter, intrigued, inquires if she considers herself a suspect, and Greer dismisses the notion, arguing that her involvement is too blatant to be overlooked.
Just as the conversation takes a turn, Henry's call to Carter shatters the moment. He reveals a damning piece of information: Greer was on a call with Broderick, a notorious thug, mere half an hour before Merritt's demise. Moreover, Shooter had wired Broderick a substantial amount of $300,000, and since Merritt's death, Broderick's calls to Greer have been relentless. Carter's expression betrays his shock, and Greer, sensing the shift, abruptly rushes out.
On the night of the murder, Greer's eyes chance upon Merritt, seated peacefully by the beach. As The Perfect Couple's Episode 5 draws to a cliffhanger, a figure approaches Merritt, greeted warmly with a smile, leaving viewers to ponder the identity of this mysterious visitor and the implications it holds.
