Episode 6 of *House of Guinness* opens with a jarring scene: Ellen’s brother, Patrick, is hauled away by British authorities alongside other Fenian men. The news quickly reaches Ellen, who is consumed by worry. Meanwhile, their staunch advocate, Mr. Isaac Butt, arranges a clandestine meeting with Edward and Arthur to deliver a chilling warning—a death threat looms over the two brothers. Isaac voices his grave concerns about the perilous deal Byron brokered, cautioning that Edward’s withdrawal could cost him his life. He proposes dispatching a coded message to New York, enlisting Sean’s aid. Sean, however, is preoccupied with a steamy entanglement with Olivia, oblivious to the unfolding drama.

Ellen, desperate, pens a letter to Edward, pleading for his help in Patrick’s plight. During a prison visit, she vows to right the wrongs, but Patrick, bitter and suspicious, accuses her of spending the night with Edward. Meanwhile, Arthur and Isaac are stunned to uncover Edward’s romantic entanglement with Ellen. In a private, tense conversation, Edward and Arthur confront the reality of their situation, deciding to weaponize Edward’s relationship with Ellen to their advantage. Arthur, ever the strategist, teases Edward about his “Fenian flame” before turning his attention to Adelaide. He urges her to consider marrying Edward, framing it as a noble act that would empower her to aid the impoverished.
Later, Arthur pays a visit to the brewery, where he crosses paths with Patrick. Their encounter is laced with flirtatious banter, hinting at an unexpected connection. Meanwhile, Anne, ever the matchmaker, urges Adelaide to accompany Edward to the village of Cloonboo, hoping the trip will ignite a romantic spark. Edward, however, seeks out Ellen to propose a plan: Patrick will be exiled to New York, escaping British oppression and, in turn, aiding the Guinness empire’s expansion. Ellen, furious and betrayed, accuses Edward of exploiting her affections to extricate himself from a precarious situation.
Two months later, Patrick finds himself in New York, greeted by Byron and Eamon. Byron, with a hint of resignation, admits he had little choice but to comply with Edward’s demands. The episode closes on a note of uncertainty, as alliances shift, loyalties are tested, and the shadow of betrayal lingers over the Guinness family.
In Dublin, Adelaide receives an invitation to stay at the opulent Iveagh House, where she is set to collaborate with Edward on implementing reforms for the local populace. Stunned by the extravagant lifestyle of the Guinness family, Adelaide contrasts it sharply with the plight of Dublin's citizens, particularly those in the impoverished area of Cloonboo. Venturing out to Cloonboo, she encounters Sultan, who is attentively caring for a ailing young man.
Just then, Edward arrives on horseback, eager to assist Adelaide, and is confronted with the stark, grim realities of the city they inhabit. Moved by the scene, he resolves to aid the people and commands his guards to gather and distribute resources to the residents of Cloonboo. Edward even takes up a shovel himself, contributing to the digging of a grave for one of the deceased.
Adelaide, however, challenges Edward's motives, accusing him of merely putting on a show to win her favor. Edward, though, sets the record straight, revealing that his transformation is inspired by a woman he has only just met. As they make their way back to Iveagh House, Edward and Adelaide engage in a heartfelt conversation about Ellen and their childhood memories, forging a deeper bond in the process.
Meanwhile, Arthur extends an invitation to Patrick, urging him to attend a party that night. Instead of going to Arthur, Patrick crosses paths with Reverend Henry and informs him of the gathering. Seizing the opportunity, Reverend Henry devises a plan to publicly expose Arthur's sexuality. In a parallel scene, Edward and Adelaide share an intimate dinner at Iveagh House, sipping wine and engaging in playful banter.
Adelaide's stance towards Edward begins to thaw, and as the night unfolds, Patrick joins Arthur at the party, where Sean and Olivia find themselves drawn to each other. Across town, Edward and Ellen find their thoughts drifting towards one another, while Adelaide's mind lingers on Edward.
The episode draws to a close with Reverend Henry anxiously awaiting the stroke of 10 o'clock, poised to alert the authorities and set in motion Arthur's arrest.
