As I see it, this is probably how it unfolds:
1. NK wins at Winterfell.
2. Survivors of the North fall back to the Iron Islands, where they defeat some last semblence of Euron trying to win back the islands from Yara.
3. Cersei is about to be beseiged after the NK runs rampant through the Riverlands. The Eyrie is relatively safe. She sends out ravens begging for help.
4. Jon is too good a person/Dany wants her throne/Tyrion and Jaime urge action, they come up thru Highgarden (maybe we join up with some Dornishmen?)
5. Jaime and Tyrion are sent to negotiate Cersei's surrender so they can adequately defend the city without worrying about her bullshit.
6. Cersei says, "I'm pregnant, it's yours, Jaime, I love you, join me, betray them!" Jaime looks at her funny.
7. Tyrion looks away because he knows what comes next.
8. Jaime moves in as if to kiss Cersei. He instead stabs her in the belly (or maybe intimates that he's gonna kill her), recognizing her madness and how she'd get everyone killed for some baby who she already values more than the rest of the kingdom.
9. As she's dying (or doomed to die), Cersei cries: "But the witch! She said my younger brother would kill me!"
10. Tyrion, ever the smartass, points out Jaime, while her twin, was born after her.
11. Jaime looks at her sad, and decides to end it quickly because he loves her too, saying......."The things I do for love."
FIN episode 5.
Episode 6: deal with the NK.

As an aside, the "political storyline" in episode 6 will be between Jon/Sam/Sansa and Dany and her people, if she has any left by that point.
