As the news of Rayburn's involvement in the carrier attack spreads like wildfire across the globe, Trowbridge's fist serves as the ignition, igniting the world's gaze upon the White House, waiting for its response. Hal, unwavering in his conviction, advocates for a tough-love approach, suggesting a bold stance rather than an apology or retreat. Despite the protests brewing on the streets and the global mood turning sour, his ideas are met with skepticism.
Kate navigates through the protestors with deft precision, her car a sanctuary from the chaos as the Secret Service's orders echo in the background. Her phone rings, Billie on the other end with a plan of action. Grace Penn is prepared to counter Trowbridge's rogue statement by rectifying the record and confirming Roylin's involvement. If Trowbridge refuses to play ball, the US is prepared to go rogue and throw him into the fire, threatening a rapid descent into hostility between the two nations.
Kate, however, is focused on the PR battle for survival and sees her lie to Stuart about Rayburn's involvement as a necessary evil to achieve that end. Little does she realize that this white lie will shatter his resolve and question his career choices.
In the midst of this turmoil, Callum reaches out to Kate in a sneaky fashion, sneaking onto the ground and their conversation becomes awkward until they are left alone, out of earshot of the hired help. Callum reveals that they have located the submarine twelve miles off the coast, but with current technology, it's impossible for him to retrieve it...but not for the US.
Trowbridge's actions serve as a formidable obstacle, considering the recent debacle with the last ship at sea and their current predicament. Kate, therefore, must not only wield her influence to coerce the Prime Minister into including Roylin in his statement or face dire consequences, but also woo him into allowing the United States to lend a hand in the submarine crisis.
A stroke of good fortune finds Kate and Callum indulging in a steamy moment in the upstairs room while the house is theirs alone. It's a fleeting moment of passion and amusement amidst the chaos that surrounds them.
Afterward, Stuart calls Kate to confess that he's unable to arrange a meeting with Trowbridge; no one in London is responding. However, Callum offers a different take on the situation, which Kate shares with Hal when he calls her later. Though not exactly enthusiastic about the idea of these two fawning over each other, there's a deeper thought process at play.
Trowbridge isn't hiding as they initially thought. Eidra learns that he's arranged two last-minute meetings—one with China under the guise of discussing robotics, but in reality, it seems highly likely a maneuver to enlist China's help in dealing with the Russian submarine situation.
Realizing Trowbridge's quiet agenda and the need to quell this fire before it spreads and gets worse, Kate acts swiftly. Billie, however, downplays the threat, prompting Callum to suggest bypassing her and going straight to Hal. The urgency stems from the fact that this submarine carries deadly weapons—specifically, The Poseidon, a bomb designed to maximize radio fallout.
This revelation is enough to finally sway Billie and Hal into informing the President about the threat. But Callum remains unconvinced; it turns out he was once a soldier and his involvement is personal. He's known about The Poseidon for months and has kept this information under wraps, only now deciding to share it with Kate when things have hit a critical juncture.
Kate scoffs incredulously, her eyes widening in disbelief as she declares that Callum is but another version of Hal. Exasperated that he has essentially left her to clean up the mess, she unleashes her frustration, pointing out the striking similarities between the two. Meanwhile, Stuart is deeply concerned about the fallout from the events that have unfolded. Billie agrees that he may need to seek legal counsel and distance himself from the chaos.
As for the messy truth, Hal reveals to Billie amidst the chaos that he and Kate are separated and divorced. There's little else to say on this front, as the real news stems from Callum's revelation.
Up at the house, Callum informs Kate that Grace has reached out to Trowbridge and proposed a bilateral summit in the UK to mend fences. Remarkably, Trowbridge has accepted. Callum is adamant about not wanting to be compared to Hal, a sentiment understandable given the circumstances. While Kate admits her concern that she might not treat people as they deserve, she nods in agreement with Callum's suggestion of starting anew. Yet, it remains uncertain whether these two will actually endure as a couple.
