Hinges on:
- Nobody mentioning that Littlefinger sent Sansa to the Boltons
- Nobody mentioning that Littlefinger has had Sansa in the Vale for at least months
- The Bolton's not speaking to the family they happen to have brokered an alliance with
- He gets the title of Warden of the North...and then what? He hands Sansa over? He kills Sansa? He breaks his alliance with the Lannisters?
It's a convoluted justification that has been spun to get Sansa into Jeyne's position.

None of that story arc makes any sense, the showrunners are trying like hell to consolidate and streamline disconnected plot lines without actually thinking if the plot makes any logical sense.
The pointless and terrible Dorne side plot makes their attempts to combine plots that don't really fit even worse, that shit should have never been invented.
The way I see it all of the plotting issues the show runners are having is from abandoning the riverlands/BwB plot lines, as that basically tied the various plots to do. Without that plotline you have to think up this bullshit trip to dorne to give Jaime something to do, you have to put Sansa back it a shit position so you can continue the Brienne story(in a really shitty way).
This is why I never understood the people who said cutting LSH doesn't matter. The riverlands plot ties all of the westeros story lines together. People always argue that because a character doesn't make many impactful moves that you can write them out, but then you have to either write out every character that is involved in that character's plots, or give them something new to do. The small changes over time add up to the point there there is nothing connected the plot threads anymore, and we are about reaching that point with the number of changes the show is making.
You cut like at least a 3rd of the time of Daenerys's shit which is too slow moving anyway, you cut Dorne and you cut the iron islanders even earlier if you were going to cut them anyway, and you have plenty of time for a riverlands plot line that gives Jaime and Brienne something to do that isn't complete shit.
