All the biggest moments from the explosive 'Game of Thrones' season 7 finale

The Stark sisters acknowledge their differences and compliment each other on the skills they used to take down Littlefinger.

Arya tells Sansa, "You're the strongest person I know." And then Sansa quotes their father as they look out beyond the castle:

"When the snows fall and the white winds blow, the lone wolf dies, but the pack survives." This quote perfectly sums up how the Stark siblings just worked together, combining their unique skills to take down the man responsible for destroying their family.

Bran tells Sam he's the Three-Eyed Raven. And Sam, speaking for all of Westeros, says "Oh! I don't know what that means."

Bran briefly explains and begins to tell Sam how he has to tell Jon, who's on his way back to Winterfell, that his true parents are Rhaegar Targaryen and Lyanna Stark. Bran says his real name is Jon Snow.

But Sam puts together the little, but very important, nugget of information that Gilly found in the High Septon's diary the last time we saw them. That's the revelation that Jon is actually not a bastard, because they were married, and Bran then witnesses the ceremony with his powers.

Jon is the legitimate heir to the Iron Throne.

In an excruciating sequence, we see Jon and Daenerys hook up, the true weight of their actions unknown to either — they are technically aunt and nephew. As one incestuous relationship ends, another begins! Meanwhile, Tyrion broods in the hallway outside.

Oh, and she also threatens to kill him. And it was really convincing for a few seconds before he calls her bluff.

Cersei sees Jaime planning their journey North with some of the Lannister soldiers. Cersei asks him what he is doing, and he says something very reasonable along the lines of "Uh, planning how we are gonna fight thousands of those horrifying zombies we just saw."

But she then reveals to him that she lied to Jon Snow, Tyrion, and Daenerys — she doesn't plan to help them fight the dead, and never planned to. She has the Iron Bank on her side, and has Euron in Essos getting some paid soldiers. But Cersei is a fool for thinking tht paid soldiers will protect her against dragons and zombies, and Jaime knows this.

Jaime, perhaps inspired by his conversation with Brienne earlier in the episode in which she screams "F--- loyalty!" at him, finally abandons his sister (it's about time, Jaime!). The next we see him, he's riding a horse alone in the rain.

The writers made both the audience and Littlefinger think that Sansa and Arya were actually falling for his plan to create friction between them. Sansa, with the help of Littlefinger, arranges for Arya to answer for her "crimes" against Sansa.

Instead, this is all a grand plan by Sansa, Arya, and Bran to execute Littlefinger for his many, many crimes that led to tragedy in the Stark family. Sansa reveals Littlefinger's murder of Jon and Lysa Arryn, and Bran confirms his betrayal of Ned and Catelyn Stark with his Three-Eyed Raven gift.

Arya slits Littlefinger's throat with his own dagger, and viewers all over the world cheered.

Who knew Theon Greyjoy and The Mountain could have anything in common?

Before Theon bashes in the face of an Ironborn who refuses to help him get his sister back from Euron, he meets with Jon in the Dragonstone throne room.

And before Theon tells Jon that he has to part ways to go save his sister, Jon kind of, sort of forgives him for his betrayal of th Stark family. Jon says, "You're a Greyjoy and a Stark."

And it's one of the best scenes on the show in years, because it proves how good Tyrion is at being Hand.

Even though it would likely end with his death, Tyrion meets with Cersei alone in an attempt to make up for Jon Snow's stupidity. He basically begs her to have zombie The Mountain kill him, but she won't give the order.

He apologizes for the deaths of her children, Myrcella and Tommen, who he loved. And even apologizes for murdering their father, Tywin.

Tyrion also realizes that Cersei's fear is because she's pregnant. She rubs her belly in front of him, causing him to figure it out. After their conversation, Cersei comes back and says she will help fight the dead, and will bring all of her men to Winterfell.

Back in Dragonstone, Team Daenerys plans to sail for White Harbor and head to Winterfell.

In the dragon pit, The Hound immediately goes up to The Mountain. He notices his creepy zombie eyes and says, "You're even uglier than me now. What did they do to you?" Then he says, "You know who's coming for you," which could confirm that we'll get Cleganebowl sometime in the last six episodes.

The two bond over their fondness for Arya Stark, and Brienne confirms that she's safe in Winterfell and can protect herself now.

Tyrion leads his group of heroes into the dragon pit of King's Landing, where they're to meet Cersei to discuss a truce and introduce her to an undead wight.

Cersei has a look of terror on her face as the wight gets within inches of her, and everyone else who's never seen them before does as well. Except for Qyburn, who looks at it like it's pizza delivery.

Jon Snow stupidly tells Cersei that he will stay loyal to Daenerys, no matter what.
