Episode 4 of *Old Money* opens amidst a cloud of anxiety, as Mahir and Arda find themselves fretting over the looming threat to their family's existence following Engin's declaration of war. Mahir is resolute in his conviction that their days are numbered if the mighty Naz Corporation sets its sights on their demise.
Amidst this tension, Mahir's phone buzzes with a message from Asli, extending an invitation to her album launch concert. Seizing the opportunity, Arda promptly asks Mahir to secure an extra ticket for him.
The following day, Arda extends the concert invitation to Berna, who readily accepts. When she inquires whether the invite is work-related, Arda responds with a touch of intimacy, "It's about you, Berna." This revelation sends Berna into a frenzy; she promptly purchases a bottle of gin and dashes off to spend the day drinking with Nihal. During their merry session, Nihal receives a call from Oyka, informing her that the loan has been approved. Nihal, however, doesn't jump at the offer, stating she'll need time to consider it.
Meanwhile, Osman is stationed at Oyka's office, tasked with assisting Nihal with the loan process. His disappointment is palpable when Nihal doesn't immediately accept, contrary to his expectations.
Later, as the family gathers for a barbecue, Osman's frustration over Nihal's decision simmers just beneath the surface. Mahir, sensing the tension, inquires about their strategy against Engin, prompting Osman to mention the turbines project. He then drops a bombshell, announcing that the family will be relocating to the mansion.
Arda, consumed with worry for Nihal, is reassured by Osman, who coldly remarks that it was her choice. Despite his efforts to offer her an escape route, Nihal had chosen to sign the papers and sever ties with their family.
Elsewhere, Gokhan delivers the signed documents to Songul, who, in a display of warmth, invites him in for a drink. The atmosphere between them is light and convivial, hinting at a budding camaraderie.
Gokhan's arm is wrapped in a bandage, and he claims it's the aftermath of a sporting mishap. Songul also discovers during their conversation that Gokhan is an avid tennis player and mentions that she typically declines invitations from the girls at the clubhouse. However, Gokhan extends an offer to become her coach. After Gokhan departs, Songul confides in Osman about her internal struggle concerning her age and dating life. Osman reassures her of her beauty, which Songul acknowledges with gratitude, noting that Osman has undergone a transformation. She's uncertain whether this change is for the better or worse.
The following day, the brothers set off for the concert. Mahir and Osman share a ride, while Arda takes the wheel since he's picking up Berna. Meanwhile, a group of old-money friends assembles at Nihal's residence for drinks as Berna waits by the gate, insisting she's heading out for work. Nihal escorts her to the entrance, and Osman is delighted to see her in a cozy, homely outfit.
At the concert venue, Mahir has a change of heart and decides not to go inside. Osman attempts to persuade him, pointing out that Asli will be devastated. They both observe that Asli has clearly chosen to be with Mahir, yet he remains hesitant. Mahir concludes that he's not worthy of Asli and opts to leave. Osman chooses to accompany him, while Arda and Berna stay behind, thoroughly enjoying themselves.
After the concert, Asli ends her relationship with Mahir via text message. A tipsy Berna decides to spend the night at Nihal's place. In her inebriated state, she recounts the Bulut family's saga to Nihal, admitting that falling in love with Arda comes effortlessly to her, and thus, she shouldn't. Meanwhile, Osman receives a text from Oyka informing him that Nihal hasn't responded to the loan inquiry.
The next morning, Nihal is at Engin's house, planning to join him for breakfast. However, she receives a text from Osman stating that he's at her office, prompting her to rush off. On her way, Nihal exhibits a mix of anxiety and excitement.
Upon arriving at the office, Osman and Nihal engage in a heated argument. Nihal had been looking forward to Osman finally opening up to her, but instead, she's confronted with his cold, businessman demeanor—a veritable monster. They engage in a verbal tug-of-war, neither willing to be the first to voice their true desires.
Nihal grants Osman one last opportunity, urging him to reveal something deeply profound—a truth that lays him bare, a secret known to no one, not even within the close-knit Buluts family. Osman, with a tremor in his voice, confesses his profound fear of existing in a void of self-ignorance. He delves into how the cataclysmic disaster has indelibly shaped his existence, yet he remains haunted by the void of memories predating the earthquake. The absence of his mother's visage in his mind's eye is a wound that festers, exacerbated by the lack of even a single photograph to weave fictional tales around.
Nihal, her heart aching with empathy, attempts to offer solace, but Osman, ever the master of deflection, swiftly steers the conversation onto a different course. He, too, yearns for a revelation from Nihal, a peek into the enigma of her decision to abandon the sanctuary of their childhood home and embark on a path of departure. Nihal, her voice laced with vulnerability, admits that fear is her constant companion, a relentless specter that gnaws at her very soul.
Osman, sensing the depth of her turmoil, inquires about the source of her dread. Nihal, her eyes glistening with unshed tears, confesses that it is he who instills fear within her. In a moment of raw intimacy, Osman draws her close, his arms a sanctuary against the storm. "Let me be your guide," he whispers, his voice a promise of protection. The scene culminates in a tender kiss, a silent pact between two souls adrift, seeking solace in each other's embrace.
