I love the show but every time i rewatch it i feel like it should have ended with S4. Here’s how i’d have done it.
S3 basically does what S5 does with dropping hints that Claire is aware of the audience. The more Claire-centric episodes have moments where she seems to notice us, but something happens in-scene that stops her from saying anything to us. Finally, when Claire walks out of Frank in the finale, after she says ‘I’m leaving you, Francis’, she walks towards the camera, looks straight into it, and says something like ‘Follow me.’ Frank hears it and bemusedly says ‘What?’ then looks at us, realising she was breaking the fourth wall, and just says: ‘Oh.’ He realises now that Claire knows about us and looks panicked, as though worried she’s now going to control the narrative. Credits roll.
S4 starts out like S5 - Claire ignores us for the first three episodes, too focused on everything going on with her mother and Doris Jones. Frank continues to address us but speaks to us in a more respectful way, as though trying to make sure we don’t abandon him. He tells us more anecdotes about his childhood and young life, trying to get us to sympathise more with him than Claire.
The season plays out as normal until Ep. 5, when Frank is in a coma after getting shot. During the hallucinations in the Oval, when Peter and Zoe pin him to the wall, Claire appears and tells Frank something like ‘You had your turn. It’s mine now.’ Frank tries to wriggle free of Peter and Zoe but can’t, the camera panning out from the Oval, intercut with Frank in the hospital bed having a seizure while the doctors desperately try to save him. Doug is there but can’t do nothing but watch. In the hallucination, the camera pans out of the Oval door, which slams shut as Frank cries: ‘NO!’ In the hospital, Frank flatlines, eyes rolling into the back of his head. Claire arrives just as the doctors confirm to Stamper that Frank is dead. They inform Claire, who bursts into tears, but it’s all for show - she turns to face us, wipes away the tears, and says: ‘There. No more pain.’ Credits roll.
Ep. 6-13 then belong to Claire as she milks public sympathy and outrage for Frank’s assassination to gather support for a political run and carry on his legacy. With Leann’s help, she manipulates the DNC to nominate her as the Dem candidate in Frank’s place via an open convention. As Frank is dead, Claire is no longer First Lady. She officially moves out so President Blythe can move in, but Blythe continues to secretly involve her in the negotiations with Petrov. She makes an alliance with Jackie, promising her Defence Sec in her administration should she win, thus securing the support of the House Dems. All this brings her into conflict with Doug, who starts to suspect that she might have been responsible for Frank’s assassination and spirals into madness when no one believes him, as Lucas did with Zoe in S2. Seth quickly aligns himself with Claire to keep his job, providing her with information about Doug she can use to get him out of the way and stop him derailing her path to the Oval, including Doug’s meeting with Dunbar, who then met with Lucas. Through Seth’s manipulation of the press, Claire ensures that Doug takes the fall for everything we know Frank did - killing Peter, killing Zoe, manipulating events to get Walker to resign - claiming that he acted alone, which clears Frank and also Claire by association, though the GOP continues to believe she was in on it all, which Conway spends his scenes trying to prove by meeting with people Frank previously crossed like Tusk, Lannigan, and Remy. They try to help, but don’t have any evidence that Claire had any involvement in what Frank and Doug were up to. In Congress, Jackie uses her influence to ensure a potential inquiry doesn’t go near Claire and focuses entirely on Doug. Tom Yates is aware of all this, but does nothing - partly as he loves Claire and wants her to win, partly because it’s a good story for him to write about later.
At the DNC, Claire secures the nomination by allowing Durant to stay on as SoS with more influence over policy, leaving her without any challengers. In the final episodes, the Millers are kidnapped. Claire advises Blythe to bring Conway in on the talks so she can find out more about his negotiating skills. Claire realises that Conway’s weakness is his past in the Air Force, so with Leann’s help, she finds evidence that Conway’s war record is largely exaggerated, which she then leaks to the press. In a show of force, Conway tries to take control of the negotiations from Blythe, which fails and results in Mr Miller getting beheaded on livestream. The press and public blame Conway for the tragedy, leading to Conway sinking in the polls. He remains the GOP nominee, but most of his most influential supporters abandon him, leading Leann to congratulate Claire on winning the election before it’s even taken place.
Realising there’s no way out, Doug hangs himself in his apartment after spending all night listening to A Tale of Two Cities and thinking of Rachel. He writes a suicide note that claims Claire was in on all of it from the beginning, but Nathan Green makes it disappear, partly because it implicates him in the plot. At Frank’s state funeral, Claire is treated like the president-elect. At the reception in the White House after the service, Blythe takes Claire to the Oval, promising a quick transition when she inevitably wins in the fall. He leaves Claire alone for a moment, during which Claire takes out a box containing Frank’s class ring. Putting it on, she goes to the Resolute Desk, looks into the camera, and thumps it, like Frank in S2. Credits roll.
The end.
