The second episode of "We Were Lies" unfolds on August 16th, marking the poignant moment when Cadence finally emerges from her coma, yet her memory remains a blank slate beyond the kiss she shared with Gat in June. Ensnared by a dependency on painkillers and shrouded in melancholy, Cadence undergoes a transformation, altering her hairstyle in a bid to reclaim some semblance of self. Distressed, she discovers that The Liars have shut her out for an entire year, refusing all communication. Determined to jog her memory and confront them, she insists on a trip to Beechwood Island for the summer of 17.
Upon her return, the scenery has shifted dramatically; Penny's perpetual cheerfulness has dimmed, and Carrie appears haggard. The once-rustic charm of the main house has vanished, replaced by a sterile, modern structure christened New Clairmont.
Flashing back to summer 16, Gat hands Cady a letter, albeit devoid of the flower she had witnessed him attaching. Perplexed by its absence, she confides in Mirren. The morning progresses with Brody's arrival, having missed his flight and enduring a grueling drive instead. Bess is consumed by guilt, while Mirren is visibly upset. Brody, embodying the stereotype of a finance bro, exhibits a condescending demeanor towards Ed. They venture into town for ice cream, where Mirren reveals Bess' affair to The Liars. Gat is inclined to give Bess the benefit of the doubt, but Cady stands firm, insisting that infidelity cannot be excused. As they depart, Mirren attempts to create a private moment for Gat and Cady, yet he feigns obliviousness.
Back at home, Bess yearns for a heart-to-heart with her sisters, but their conversation devolves into a contentious debate over who has presented the best Father's Day gift for Harris. Tipper fuels the fire, announcing that the necklace of black pearls – the very one Cadence clutched during her accident – will be awarded to the winner.
As the others make their way to the island, Ed endeavors to enlist Brody for his consultancy expertise. Brody nonchalantly remarks that he only caters to affluent clientele. Meanwhile, Gat lends Cady a helping hand aboard the boat, sitting beside her as Mirren grins mischievously, while Johnny's face betrays his discontent.
In the summer of '17, Cady finally encounters The Liars, who greet her with joy. Bewildered, she seeks clarification, and they explain that it was deemed best for her to reclaim her memories unaided. Penny's arrival interrupts, insisting that Cady welcome Harris.
Flashing back to summer '16, Mirren and Cady ponder Gat's peculiar behavior. As The Liars engage in idle chatter, Gat raises the sensitive topic of colonization and the displacement of indigenous people, akin to the plight of Beechwood Island's natives. The Sinclair Liars, seeking to resume their playful antics, jestingly silence him, leaving him feelings hurt and excluded.
Indoors, Tipper replaces a painting, using the expense as a pretext to cover Penny's divorce costs. Penny finds this unethical, but Tipper counters that Harris, prone to probing into her finances, might uncover the true nature of the expenditure. Ed, yearning to propose marriage to Carrie, faces an uphill battle. Harris mocks him mercilessly, even resorting to insulting him. However, Tipper's timely arrival salvages the situation, earning Ed Harris's blessing. Soon after, Harris departs to enjoy a round of golf with Brody.
Cady apologizes to Gat, explaining that when they tell him to shut up, it's actually a playful expression of their affection. Their tender kiss is abruptly cut short by Harris's amusement, causing the flustered couple to scamper away.
Returning to summer '17, Cady wonders if Gat has betrayed her trust. He pleads with her to comprehend that he is forbidden from discussing the events of summer '16. Suspecting him of withholding crucial information, her doubts linger.
Flashing back to the summer of 2016, Johnny joins Cady and Gat, whose thoughts are clouded with concern for Harris. The conversation veers off into a集体吐槽 about how Father's Day truly sucks. Johnny attempts to pitch prank ideas, only to be repeatedly shot down by Gat, who fears the repercussions on the ecosystem or the potential dismissal of staff. Frustrated, Johnny labels Gat a hypocrite for always raining on everyone's parade. Tempers flare, leading to a physical altercation that Brody swiftly intervenes to stop.
Later, Cady inquires about the skirmish with Johnny, seizing the opportunity to bring up the mysterious flower. Gat's vague responses leave her visibly disturbed.
On Father's Day, amidst the grand celebration, Cady takes the chance to snoop around Gat's room and discovers the flower-adorned letter intended for his girlfriend, Raquel. Spying on Raquel, Johnny reveals his awareness of their relationship and offers her solace.
Back at the main house, Cady shuns Gat, drowning her sorrows in alcohol. Tipper remarks that nothing can deter a Sinclair, prompting Cady to rally herself.
Gat seeks her out by the shore, confessing his relationship with Raquel. She insists that her Gat would never stray. This infuriates him, and he retorts that she never really understood him.
He confesses his lifelong love for her, dating back to when he was just 12, but laments that she has never seen him for who he truly is. She overlooks everyone who isn't wealthy and white, much like the rest of her family, who exploit people like him without a second thought. He regrets their kiss, leaving her heartbroken.
In the summer of 2017, Cady begins to reclaim fragments of her memory, including recollections of Raquel. She confronts her mother, wondering if she attempted suicide or if someone had harmed her. Penny remains tight-lipped, insisting that Cady can only cope with her pain by retrieving her lost memories. As Cady storms away, she observes The Liars sitting together on the beach.
In another scene from summer 2016, the three sisters and Tipper indulge in drinks together, aware that none of them has secured the title of Best Daughter. The scene cuts to Harris, his smile tinged with sadness, as he listens to a recording of his deceased daughter, 8-year-old Rosemary. The episode of "We Were Liars" concludes on a heart-wrenching note with Tipper's sudden death, leaving everyone devastated.
