Episode 2 of "Sirens" kicks off with an exhilarating scene of Devon swimming stealthily towards Cliff House under the veil of night, equipped with a snorkel. Jose, alerted to an unexpected visitor, peers into the surveillance footage and spots Devon's determined figure. She manages to reach Simone's room, where she urgency conveys her desire to rescue Simone from her current surroundings. However, Simone, despite everything, insists she is content where she is and refuses to return to Buffalo.
The sisters' disagreement escalates, with Devon reminding Simone of her dream to become an attorney, while Simone counters with accusations about Devon's affairs with married men. Just then, Michaela reappears, unable to sleep, and climbs into bed next to Simone, effectively halting their heated conversation. She orders Jose to escort Devon to the guesthouse, but instead, he guides her straight to a police vehicle, where Devon is subsequently arrested for trespassing.
Back in the bedroom, Michaela inquiries why Simone never disclosed having a sister. Simone responds that Devon brings her sorrow. Michaela probes further, asking if there's anything else Simone has kept hidden, to which Simone asserts that Michaela knows her intimately.
Meanwhile, Devon is astounded to discover that even the police officer escorting her is aware of Simone's identity.
As dawn breaks, Peter Kell finally arrives home, encountering Patrice, the cook, and engaging in lighthearted chatter. While incarcerated, Devon is informed by another inmate about Rory and Sarah Kell, Peter's children from his first marriage to Jocelyn. Rumors abound that Michaela might be responsible for Jocelyn's disappearance, as no one has heard from her lately. The inmate also shares her own past in a cult and offers Devon advice on escaping, recounting how her father infiltrated the cult to rescue her.
In the morning, Michaela greets Peter warmly, and soon Simone joins them, presenting a detailed schedule for the day. Peter expresses reluctance about the photoshoot, but Michaela persuades him otherwise. As a token of appreciation, he gifts Michaela a souvenir from Tokyo, hailing from a charming place called Magpie.
Simone subsequently issues meticulous directives to Jose and his team, tasking them with arranging a solemn funeral for Barnaby. Meanwhile, she receives a call from Magpie, who resides in Tokyo, requesting the dispatch of a particular type of chocolate.
In a dramatic twist, Devon is extracted from her confines and escorted to Michaela's presence. Michaela highlights the gravity of Devon's situation, emphasizing that a second DUI conviction could lead to a four-year prison sentence. However, Michaela presents her with an alternative: to simply depart and return home immediately. In a calculated maneuver, Devon pleads with Michaela to mentor her, much like she did with Simone. Michaela reluctantly agrees to keep her for the weekend, under close watch.
Jose conveys Devon back to the guesthouse, revealing that Michaela has procured new attire for her, compelling Devon to adopt a similar dress code as Simone. As she enters the room, she discovers Simone and Michaela preparing for a prestigious Vanity Fair photoshoot. Seizing the moment, Devon pulls Simone aside and feigns a change of heart, hoping to gain her trust.
Devon encounters a photographer and attempts to pitch a whistleblower story, but he declines her offer, leaving her disheartened. Meanwhile, Simone and Michaela venture into another room where Peter and Jose await. Peter discreetly sends Simone away and then reveals security footage to Michaela, showing Simone embarking on mysterious nocturnal excursions. They deduce that she must be having an affair with Ethan, and Michaela comments that Simone fits Ethan's typical preference: "a 25-year-old visitor here for the summer." Overhearing this conversation, Simone feels deeply hurt and betrayed.
Elsewhere, Devon engages in conversation with other women, discovering that they are part of a wildlife preservation society led by Michaela. She stumbles upon an unlocked door and ascends a tower, where she finds Peter smoking. He indulges Devon in a cigarette and heaps praise on Simone. Intrigued, Devon brings up the topic of Peter's children and first wife, prompting suspicion in Peter's mind.
Simone finds herself confined within a room, her sobs echoing off the walls as she collapses in despair upon the floor for what seems like an eternity. Meanwhile, Devon scours through Simone's belongings and comes to a startling realization: her medications, untouched and neglected. Her attention is then drawn outdoors, where she spots Jordan—alias Morgan—strolling across the grounds. Urgently beckoning him over, she retrieves her phone and unmasks her undercover mission, determined to rescue Simone. In a rush, she disconnects from the brief encounter to address Ray's relentless calls.
A sense of unease gnaws at Michaela, her thoughts constantly drifting towards Simone. Realizing the eulogy for their beloved bird is stored on Simone's phone, she tasks Jose with locating her friend. Ray's voice cracks through the phone, his reluctance to shoulder the burden of caring for his father plain in his words. Devon's conversation with Ray is abruptly halted when she catches sight of a blonde woman darting into the forest. Her curiosity piqued, she chases after the mysterious figure, her eyes catching sight of Michaela's heartfelt eulogy before she continues on, witnessing Michaela and Ethan strolling together in a serene moment.
Jose, having noticed Devon's covert actions, steps in, guiding her to continue her pursuit. He leads her to Simone, who remains immobile, her tears a steady stream upon the cold floor. Devon's heart aches as she envelops Simone in a comforting embrace, seeking to soothe her friend's overwhelming grief.
