This one is almost inevitable: the White Walkers will make it past the Wall somehow. While the novels' Horn of Winter/Joramund hasn't really been mentioned throughout the HBO series, a workaround for the undead to make it past the Wall's magical barriers might be the way they broke into the Three-eyed Raven's cave: the Night King left his mark on the greenseeing Bran Stark, thus allowing his forces to enter. If Bran crosses the Wall, then perhaps the mark will allow the Night King's forces to follow. It'd be more badass to see the Horn of Winter live up to its book-based legend and shatter the Wall somehow, but regardless of how it happens, it's safe to say they're hitting the mainland, and Castle Black is doomed.

It's the Mother of Dragons vs. the Mother of Monsters in the upcoming war between the Targaryen and Lannister armies. Don't forget, the Lannisters' riches are pretty much depleted, and the crown owes beaucoup bucks to the Iron Bank of Braavos. With the Tyrells no longer financially helping the crown, there isn't much incentive for people to stay and fight under the Queen, especially after the Sept of Baelor blew up. With House Martell, the forces of Dorne, House Tyrell, the Dothraki horde, the Unsullied, the Greyjoy's Iron Fleet, and three massive dragons all teamed together, things are stacked against Cersei, but we all know she's resourceful. In the end, it'll probably be either Jaime or Tyrion dealing the final blow to the shameful Queen of Westeros, no matter which soldiers come knocking at her door.

The true villains of Westeros are pretty apparent—including Joffrey, Cersei, and Ramsay—except for one. Petyr Baelish has orchestrated events behind the scenes for years, going from being a lowly servant to a brothel owner to Lord Protector of the Vale. Don't forget, he betrayed Ned Stark, had the hots for his wife, framed Tyrion Lannister for the assassination attempt on Bran Stark, killed Lysa Arryn after marrying her, and confessed his love for Sansa Stark. He totally deserves to be on Arya's Kill Bill list, and he's still plotting all kinds of ways to get the throne. If there's one thing you can count on, Littlefinger will make his move when you least expect it, we just hope Jon Snow doesn't have his back to him when he does.

Once the White Walkers make rotting mincemeat out of what's left of the NIght's Watch, the undead will eventually make their way to Winterfell. We have a feeling the united North isn't going to be enough to stop it, considering there is so little Valyrian steel and Obsidian left in the world. A safer bet would be to use dragons themselves to burn down the White Walkers, and Daenerys is bringing a trio of them to King's Landing. The newly-crowned King in the North, Jon Snow, will probably need to unite all of Westeros against this necrotic force, and it's likely going to result in a massive alliance between the Stark and Targaryen armies.

After everything is said and done, with the Night King destroyed and Queen Cersei preferably coughing up venomous blood, the question remains as to how Westeros should be ruled. The show could end with Jon marrying Aunt Daeney in order to maintain peace between the North and the South as king and queen. Perhaps Sansa could be appointed Warden of the North, with Bran as her chief adviser/maester. There are all kinds of red tape outlining how the country should be united and ruled after something like this, but maybe it shouldn't…

Westeros is simply too large of a country to govern under one ruler. Even if Daenerys ascends the Iron Throne, the Northerners may never accept her, due to their fealty to the King in the North. It may be better if Westeros is amicably split into multiple territories, with Jon as the King in the North, Yara Greyjoy as the Queen of the Iron Islands, and Daenerys as the Queen in the South. We could see each leader having their own respective adviser/maester, Kingsguard, and Hand of the King. With so many characters we've been cheering on for the past few years, perhaps this is the best route, giving everyone a role of significance by the end of the show. Valar Dohaeris, right?
