Spoilers! What you need to know about this big twist in The Diplomat finale.

Spoiler! Below are the details “The Diplomat” season 2 finale.

The Weilers were really unlucky to share important news with world leaders.

A couple at the center of a Netflix soap opera political drama “Diplomat” has a bad habit of having intimate meetings with important people who drop dead mid-conversation. And judging by the particular leader who didn’t make it to the season 2 finale of the show, things are only going to get weirder from here on out.

New episodes of The Diplomat, which began airing Thursday, feature U.S. Ambassador to Great Britain Kate Wyler (Keri Russell) and her husband, ex-Foreign Service officer Hal (Rufus Sewell), as they try to save the world from fire after an attack on a British aircraft carrier. And at the end of season 2, US Vice President Grace Penn (Allison Janney) appeared on the scene to help Kate, or perhaps hinder her.

Here’s what happened in the explosive finale and what it could mean for the show’s third season (currently filming).

What happened in the finale of “The Diplomat” season 2?

Kate, Hal, and CIA chief Aidra Park (Ali Ahn) discover mid-season that the attack on the British ship HMS Courageous was a false flag operation orchestrated by posh Conservative Party operative Margaret Royleen (Celia Imrie). Roylin won’t reveal the most famous names of his co-conspirators to anyone but Hal because he’s not an official representative of the US government, but Hal will tell Kate anyway. A true mastermind? Penn, Vice President.

In the midst of this chaos, Penn appears in London, subtly manipulating British Prime Minister Nicole Trowbridge (Rory Kinnear) to keep the whole treasonous scheme a secret. She is so good at Trowbridge’s charm that the Prime Minister appears to have convinced US President William Rayburn (Michael McKean) to reconsider his plan to kick Grace out of the administration and replace her with Kate.

But after Trowbridge makes things awkward at a lavish dinner attended by Kate, Hal, Grace and other dignitaries, Kate and Hal are forced to tell Grace that they know she’s behind the attack. The Vice President takes Kate out of dinner and explains, with an inappropriately funny visual aid, that the attack was a plan to prevent Scottish independence, which would mean the loss of a key US nuclear base in the North Atlantic. So you see, she didn’t bomb a British ship because she’s a bad person, she did it to save the world from being nuked by Russia in a hypothetical future war.

Kate tries to figure out how to deal with this new information, and eventually realizes that she and Hal should just play by the rules: Hal should notify the Secretary of State and let someone higher up deal with it. Except Gel doesn’t do as he’s told.

No, he goes straight to his good buddy President Rayburn, who is so upset by the news that he drops dead on a Zoom call. Hal is running screaming through the corridors of the US Embassy in London, trying to reach Kate, who at this point is having a nice (read: super passive-aggressive) conversation with Grace about how Grace wants Kate and Hal to be quiet.

The episode ends with Secret Service agents racing through the grounds of the ambassador’s mansion to Grace and Kate, with Hal yelling into Kate’s ear, “Grace Penn is the President of the United States!”

What does this mean for The Diplomat Season 3?

So now Grace is president and only Kate, Hal and Margaret Roylin know that the new leader of the free world is also responsible for the deaths of 41 British sailors. So things will be pretty calm, right?

Probably not. Kate and Hal have become bitter enemies of the new most powerful man in the world, but they also have quite powerful leverage over her. Now there is an open vacancy for vice president, and Kate has begun to really want it, but now there is no way Grace will put Kate in such a position. Besides, it’s not What is largely a political fantasy: it is impossible for both the president and the vice president to be women, even in this fictional world.

Will Kate remain an ambassador? Will Gel have a chance to return to international relations with an official position? Will Austin Dennison (David Giassi), the British Foreign Secretary, approach Kate again? Will Kate and Hal’s marriage survive more political upheaval?

Well, at least we can predict that Jenny will return as President Grace Penn. Moreover, Allison Janney is never bad. Even when she’s playing a villain.
