Contains spoilers for the first two episodes of The Diplomat Season 4.

If the first episode of The Diplomat Season 4 ends with the President of the United States being shot, the second begins with the inevitable consequences: chaos, fear, and the possibility of a change in power. Grace Penn (Allison Janney) has been wounded at Windsor and, as security services struggle to identify the shooter, Hal Wyler (Rufus Sewell) must temporarily assume the Presidency.

It is a situation that changes everything. Especially for Kate (Keri Russell), who has spent much of the past few years trying to prevent her husband from getting too close to power.

The attack triggers an immediate response. Grace, Todd, and Billie Appiah (Nana Mensah) are transported to an American aircraft carrier, where the President receives medical treatment. Hal and Kate remain under the protection of security teams at Windsor Castle while British authorities begin searching for the shooter.

But Grace would not be Grace if she allowed a gunshot wound to interrupt her work. Even as she prepares for surgery, she speaks to Hal about what should happen if she dies. She gives instructions, considers the composition of a potential administration, and displays a coolness that leaves Todd deeply shaken.

Allison Janney is wonderful in these moments. Her Grace may be authoritarian, dangerous, and convinced of her own superiority, but she rarely loses her ability to think clearly. Not even when she is about to undergo surgery.

On the other side of the crisis is Nicol Trowbridge (Rory Kinnear), the British Prime Minister who somehow manages to turn every international incident into a personal matter. His reaction to the assassination attempt combines legitimate concern, outrage, and, of course, panic at the possibility of being held responsible.

An American President has been shot on British soil. For Trowbridge, that means someone must find the culprit immediately, before public opinion identifies a more convenient scapegoat.

It is remarkable how Rory Kinnear manages to turn an often ridiculous politician into someone who occasionally displays genuine humanity. The problem is that this humanity rarely lasts long. Soon enough, the man obsessed with his position and reputation reappears.

The investigation mobilizes several British agencies, including those responsible for surveillance cameras and transportation systems. Amid the grand speeches about national security, it is the ordinary employees and technicians who offer some of the most practical solutions. There is a rather interesting irony in that: while political leaders create crises, the bureaucracy tries to solve them. But the heart of “Redcoats” is not the investigation. It is Hal and Kate.

Because Hal Wyler was born to exercise power. At least, that is what he believes.

And, to be fair, the series shows that he actually knows what he is doing. As he temporarily assumes the Presidency, Hal demonstrates knowledge, confidence, and an impressive ability to organize priorities. He is not merely an ambitious man. He is someone who has spent his entire life preparing to be exactly where he now finds himself.

Rufus Sewell is excellent in this transition. Hal does not need grand speeches to establish his authority. He simply walks into a meeting, quickly understands what is happening, and begins making decisions. There is just one problem: Kate.

The two have an extraordinary professional relationship. She knows his impulses, anticipates his mistakes, and recognizes when he is about to cross a line. Hal, in turn, knows that Kate is brilliant and trusts her intelligence. Together, they function almost like a single political machine. Separated, or in disagreement, they can become dangerous.

And here comes a fascinating contradiction. Kate, who refused to abandon her career to become the wife of a Vice President, seems perfectly willing to work alongside Hal if he becomes President. For him, that distinction is personal. And painful.

Years of accumulated resentment surface in an argument that quickly goes beyond matters of state. Hal once again questions his wife’s choices, while Kate reminds him that he had fifteen years to appreciate their marriage and failed to do so.

It is one of the best scenes of the first two episodes because it reveals the complexity of their relationship. We are not watching a couple who simply love or hate each other. These are two people who deeply admire one another but are also constantly competing for space, recognition, and power.

Kate knows Hal so well that she can even tell when he needs something to eat to regain his balance. It seems like a trivial detail, but in a series where personal decisions can trigger international conflicts, knowing when the acting President is irritable because he is hungry is not exactly irrelevant information.

There is also a more serious issue. Billie and Hal raise the possibility that Kate might have disclosed information about Poseidon to Callum. The suspicion is offensive to her, especially after everything she has done to protect the secret. But it is also a question that must be asked in the aftermath of an attack whose motive remains unknown.

And Kate, naturally, does not react well.

Meanwhile, Stuart Hayford (Ato Essandoh) and Eidra Park (Ali Ahn) continue developing their relationship. In a universe where almost everyone seems incapable of separating personal and professional interests, the two offer a slightly more balanced perspective. The possibility of moving in together represents an important step forward for the couple.

By the end, Grace survives surgery, but the question of when she will be able to resume the Presidency remains open. Billie works to manage the transition, despite resistance from Todd, who has not forgotten the previous conflicts between the Chief of Staff and his wife.

Hal, meanwhile, has experienced something he has always wanted: presidential power. And he seems to have enjoyed it.

Kate remains in London, away from the immediate center of decision-making, while her husband prepares to move forward. It is a political and emotional separation that may ultimately prove more important than any argument about their marriage.

The second episode does not need another explosion to work. Its best moments come precisely when it slows down and allows Keri Russell and Rufus Sewell to command the screen. The two carry the series with extraordinary chemistry, even when their characters are infuriating.

I still think The Diplomat has a curious problem: its protagonists are excellent at identifying strategic mistakes and extraordinarily bad at avoiding their own. And Debora Cahn seems to enjoy that contradiction immensely.

With Grace hospitalized, Hal in the White House, and Poseidon missing, the United States is in the hands of a man who believes he is always right. That may be excellent news for Hal Wyler. For the rest of the world, I am not so sure.
