CBS FULL [9/19/2025] ‘Bold and the Beautiful’ Full Episode: Finn Secret Affair With Sheila’s Exposed
Friday’s episode of The Bold and the Beautiful brings a shocking revelation that shakes the Forrester family to its very core. For months, Sheila Carter (Kimberlin Brown) has clawed her way back into her son’s life, desperate for affection, recognition, and control. But what no one suspected—and what comes crashing into the spotlight—is the explosive truth that Finn (Tanner Novlan) has been hiding a dangerous secret: a forbidden connection to the very woman his wife Steffy (Jacqueline MacInnes Wood) despises most.
The episode begins with Steffy once again confronting Sheila in a tense back-alley encounter. Fueled by fury and desperation, Steffy demands that Sheila stay away from her family, making it crystal clear that Finn, the children, and the Forresters want nothing to do with her. But as Steffy hurls accusations, Sheila’s expression shifts—not to fear, but to something more smug, almost triumphant. For the first time, Sheila hints that she has a weapon stronger than any gun or threat of violence: knowledge of a secret Finn has been hiding.
The confrontation escalates when Finn appears on the scene, hoping to protect Steffy from his mother’s unpredictable wrath. Instead, Sheila drops the bombshell that will change everything: she and Finn have shared more than just tense family encounters. A shocking flashback sequence confirms it—Finn, torn by guilt and confusion, once gave in to Sheila’s manipulations and crossed a line he never should have crossed. The revelation that he had an affair, even a fleeting one, with his own mother’s enemy leaves Steffy reeling.
At first, Steffy refuses to believe Sheila’s words, dismissing them as another twisted attempt to sabotage her marriage. But the look on Finn’s face tells a different story. His silence speaks volumes, and when pressed, he finally admits the truth. In one heartbreaking moment, Steffy realizes that the man she trusted most has not only betrayed her but also tied himself even closer to the woman she sees as the greatest threat to their family.
The fallout is immediate and explosive. Steffy lashes out in rage, shoving Sheila and accusing Finn of destroying everything they’ve built together. Her fury is matched only by her heartbreak, and as tears stream down her face, she declares she may never be able to forgive him. Sheila, meanwhile, revels in the chaos. For her, this is vindication—proof that no matter how much the Forresters despise her, she will always have an unshakable bond with her son.
The ripple effects spread quickly. Deacon Sharpe (Sean Kanan) happens upon the scene and is stunned to learn the truth. Though he’s often defended Sheila, even he is shaken by the revelation that Finn crossed such a dangerous line. The question now becomes whether Deacon will continue standing by Sheila or finally cut ties before he, too, is dragged down by her schemes.
Back at the Forrester mansion, Ridge (Thorsten Kaye) and Taylor (Krista Allen) are blindsided when Steffy storms home to reveal the betrayal. Ridge, furious beyond words, vows to make Sheila pay for poisoning his daughter’s marriage, while Taylor can only watch in horror as her daughter’s world crumbles. Brooke (Katherine Kelly Lang), never one to hold back, fans the flames by insisting that Sheila be cut out once and for all, while Eric and Thomas rally around Steffy, offering comfort but also demanding answers from Finn.
Lee (Naomi Matsuda), Finn’s adoptive mother, also steps into the fray, furious that her son has once again fallen under Sheila’s toxic influence. Her protective instincts explode, and she warns Finn that his connection to Sheila could cost him not just his marriage but also his role as a father. If he doesn’t sever ties completely, she vows to take matters into her own hands.
For Finn, the guilt is crushing. Though Sheila manipulated and cornered him, he knows that he crossed a line that may never be forgiven. The thought of losing Steffy and his family gnaws at him, but Sheila thrives on the turmoil, whispering that she’s the only one who truly understands him. The psychological tug-of-war intensifies, leaving Finn torn between repairing his marriage and resisting Sheila’s dangerous pull.
Friday’s cliffhanger leaves the audience breathless. Steffy, devastated and betrayed, tells Finn she doesn’t know if she can ever look at him the same way again. Sheila, lurking in the shadows, smiles with satisfaction, knowing she has finally driven a wedge between her son and the woman she blames for all her suffering. And with the Forrester family preparing for war, the stage is set for a battle of loyalty, betrayal, and shocking consequences.
If this spoiler plays out fully on screen, it could mark one of the most jaw-dropping twists in The Bold and the Beautiful’s history. A secret affair with Sheila—exposed at last—doesn’t just threaten Finn and Steffy’s marriage, it sets off a chain reaction that could reshape the future of the entire Forrester family.
