Read the Script for ‘The Diplomat’ Season 3 Episode “Amagansett,” with a Foreword by Debora Cahn
In the latest season of Netflix’s acclaimed series The Diplomat, creator and showrunner Debora Cahn explores the complex world of diplomacy while unexpectedly delving into the intricacies of marriage. Throughout three seasons, viewers have come to recognize the tumultuous relationship between Kate (Keri Russell) and Hal (Rufus Sewell) Wyler—an intense couple deeply intertwined in high-stakes careers.
In Season 3, tensions rise further as newly inaugurated President Grace Penn (Allison Janney) appoints Hal as her vice president, sidelining Kate. Episode 6, titled “Amagansett,” offers a character study set at President Penn’s estate in Long Island, where an emergency meeting is convened to address the impending fallout from the U.S.’s involvement in an attack on the HMS Courageous. Amid the political strategizing, President Penn strives to maintain civility with her guests, but a dramatic disruption—a drop of blood on an oyster—completely shatters the facade.
By the episode’s conclusion, both couples find themselves at odds, and diplomatic relations between the UK and the U.S. are left in ruins after Prime Minister Nicol Trowbridge (Rory Kinnear) publicly blames his allies for the aircraft carrier attack in the Persian Gulf.
Cahn’s script for “Amagansett” includes a thoughtful introduction detailing how her exploration of foreign policy—a “Gordian knot” in its own right—revealed the series’ true focus: the often tumultuous interpersonal relationships at the story’s core.

Cahn shared insights about the evolution of The Diplomat, revealing that the central focus on Kate and Hal’s relationship emerged gradually. She noted, “It was the marriage… Episode after episode, when we were away from Kate and Hal for too long, we lost focus.” In examining the dynamics of Kate and Hal’s marriage alongside President Penn and First Gentleman Todd Penn (Bradley Whitford), Cahn highlights contrasts between the two relationships, using powerful imagery of a beach setting where underlying tensions surface dramatically.
Reflecting on the episode, Cahn emphasized the significance of the intersection between political language and human emotion, illustrating how moments of confrontation expose deeper vulnerabilities. As the episode unfolds, both couples face their own struggles, raising questions about the durability of their relationships.
As she concluded her thoughts, Cahn offered a candid perspective on marriage, humorously acknowledging her own 20 years of experience, stating, “I have no idea. I’ve only been married for 20 years. We’re just getting started.”
