The sixth episode of Sugar kicks off with a bombshell revelation for Bernie and Margit Siegel - Davy, though miraculously alive, is brain dead, his consciousness forever lost. Meanwhile, at home, Sugar anxiously awaits a call from Charlie, expecting news about Byron Stallings. Elsewhere, Stallings returns to his abode, unaware that Charlie is keeping a watchful eye from afar.
As Sugar learns of Stallings' arrival, he informs Ruby of his intention to confront the man face-to-face. Stallings receives a mysterious text message at his home, coinciding with Sugar's arrival. With a sense of urgency, Sugar instructs Charlie to take action if he fails to return within ten minutes. He steps into the seemingly vacant house, eyes scanning the interior for any signs of life.
His gaze falls upon a locked cupboard, and he's about to pry it open when the sound of sobbing pierces the silence. Following the cry, he discovers a distraught woman, but it's merely Stallings' girlfriend. Suddenly, Stallings and his associate emerge, trapping Sugar in a tense standoff.
Outside, the tense atmosphere is interrupted by a knock on Charlie's car door. Inside the house, Stallings taunts Sugar, claiming that Charlie will not come to his rescue. But Sugar, fueled by adrenaline and determination, overpowers his captors, dispatching the girlfriend and associate in a flurry of action. In the process, he sustains a stabbing injury.
Searching Stallings' phone, Sugar finds the number that alerted Stallings to his presence and retaliates by shooting Stallings dead. In a neighboring room, he stumbles upon a horrifying sight - cages filled with dogs, trapped and helpless.
As another of Stallings' associates approaches, Sugar seizes the opportunity to take his phone. Frantically trying to reach Charlie and then Melanie, he's left with no other option but to seek help from Melanie.
Meanwhile, Jonathan slowly comes to consciousness, and Bernie breaks the heartbreaking news of Davy's condition. Bernie's mind is flooded with memories of his son and the mistakes he made in raising him. After a moment of deep reflection, he announces that he and Margit have made the difficult decision to let Davy go in peace.
Sugar manages to stumble to a nearby motel, where Melanie anxiously waits. He urgently instructs her to contact someone named Henry and then collapses, exhausted and wounded. Some time later, Henry arrives and instructs Melanie to fetch more medical supplies. Once she's out of the room, Henry administers an injection to Sugar, his expression unreadable. He also retrieves a bag of blood, hinting at the severity of Sugar's condition.
As the episode draws to a close, Sugar succumbs to the effects of the injection and slips into unconsciousness, his fate hanging in the balance.
We witness Sugar peacefully slumbering in his bed, as Henry gently leaves Melanie in his care. After a brief interlude, Sugar stirs from his slumber and ventures out. His destination is clear - Ruby's abode, where he confronts her with a stark revelation - she was the one who had tipped off Stallings.
Ruby struggles to offer an explanation for her actions, merely stating that she had asked Stallings to depart, never intending for him to harm Sugar. She remains clueless about Charlie's whereabouts as well.
Sugar deduces that Stallings had mistaken Olivia for someone whom Ruby and her cohorts are shielding, all part of some mysterious 'mission.' As Ruby ascends the stairs to retrieve medicine, Sugar sneaks a peek into the drawer she had been standing by. Hidden within is a vial of medicine, a discovery that prompts his hasty departure, sensing that Ruby is likely alerting someone.
Returning to the solitude of his hotel room, Sugar decides to seize the remainder of the night as a respite. He administers something into his system, a transformational potion that alters his appearance, tinting his eyes and skin a deep azure hue as his hair gradually fades away, marking the dramatic conclusion of Sugar Episode 6.
