The 12 biggest questions we have after the 'Game of Thrones' season 7 finale

This week's episode of "Game of Thrones" set up a gloomy, zombie-ridden future for our heroes in Westeros. The Night King has officially arrived in Westeros, but Cersei privately refuses to join the fight while publicly stating she intends to.

After a show and tell starring a wight in King's Landing, a lot of character storylines move forward. The Stark children stage an epic betrayal of the man responsible for instigating everything that started the war that killed their family members. Jaime finally turns on Cersei, and the Night King takes down the wall with a newly resurrected Viserion.

But with the ice settled, we still have some burning questions that will keep us awake at night until season eight.

Here are all the biggest questions we have after this week's season finale of "Game of Thrones":

When did the Stark children's plan to betraying Littlefinger begin?

Exactly how thoroughly did Littlefinger get played? Was this planned the whole time, or only after Littlefinger pitted Sansa and Arya against each other? When did Bran tell his sisters what he knew?

The pivotal moment for Sansa and Arya could've been in "Beyond the Wall," when Arya hands the dagger to Sansa. Or they could've been playing Littlefinger the whole time, fabricating their tension so he wouldn't suspect a thing until it was too late. Our guess is the latter.

Even though Bran is strange now, he is definitely still loyal to his family, which makes us think that the Stark children had this thing planned the whole time. There's no way Bran withheld all he knew about Littlefinger until he noticed his sisters were maybe going to murder each other.

Will Jon Snow (Aegon Targaryen) accept the Targaryen tradition of incest and continue his relationship with Daenerys? Or will he end it immediately?

The scene with Jon and Theon in the Dragonstone throne room solidifies Jon's status as a Stark, no matter who his father is. Even if Stark blood doesn't truly flow through his veins (again, Jon doesn't know this yet), Jon explains to Theon that Ned Stark will always be their father.

Jon will probably be a bit traumatized when he learns his affair with Dany was technically incest, and he could choose to abandon the relationship. Incest is frowned upon in the North, and we're betting he won't abandon his morals because of his newly found identity. He is Jon Snow and he is moral to a fault, just like Ned.

Will Jon accept his true status and compete with Daenerys for the Iron Throne?

Jon admits this often: he does not want to rule. He does it because he has to. It's his obligation, like being a brother of the Night's Watch, to protect his people. He has bent the knee to Queen Daenerys.

But what will he do when he finds out he has a better claim to the throne than she does? Will he compete with her, or let her take it in his place, so he can stay in the North?

Where is Jaime headed?

Before Jaime realizes Cersei's plan is to ignore the army of the dead, we see him planning a journey to Winterfell with some of his soldiers.

Jaime is probably headed there now, possibly to warn everyone of Cersei's true intentions.

Will everyone in Winterfell eventually have to move south?

Once news spreads that the army of the dead is officially in Westeros, everyone in Winterfell (by the season eight premiere, a majority of the cast will be there), will probably head south. But where will they go?

Arya probably knows that Riverrun is empty, save for female Freys. A move South to delay and prepare for the battle with the dead could accelerate combat with Cersei, and bring everyone together again. But this time, blood will be shed.

Are Podrick and Bronn chilling in a King's Landing brothel, or will we see them in Winterfell?

If they're still in King's Landing, we're a little bit worried about them. No one is safe if they're within radius of Cersei, especially two men who are friends with her brothers.

Does the Golden Company take on impossible jobs?

Cersei and Euron's plan is to use the support of the Iron Bank to bring the Golden Company to Westeros. Cersei will use the army of sell swords from Essos to take back all the lands she lost in the South of Westeros, while her enemies fight the dead in the North.

But has Cersei taken into consideration that an army of soldiers who ar paid to fight might refuse or abandon a war that involves dragons, Dothraki, Unsullied, and literal zombies? Probably not, because this woman does not think ahead, or with her head.

Will Tyrion get his old brain back?

We got to see a bit of the old Tyrion in his amazing and chilling meeting with Cersei. He tells her to kill him, but she doesn't, instead promising to support their battle against the dead. And as smart as he is in that scene, he's not smart enough to realize that Cersei is playing him.

When will we get the clever Tyrion back? He used to think steps ahead of everyone else. Is he blinded by a fondness for Daenerys? Hopefully hearing Daenerys and Jon getting intimate on the boat will snap his mind back into action. Westeros needs him to survive.

Will Theon find Yara?

In King's Landing, Euron announced that he's heading back to the Iron Islands, and Theon plans to follow him to get his sister back. But Cersei tells Jaime that Euron is actually headed to Essos to bring the Golden Company to her.

What does this mean for Theon's mission to rescue his sister? And what will Theon's mission have to do with the rest of the story moving forward?

Now that they've made it past the Wall and are in Westeros, will the Night King's army still march so slowly?

It took them seven whole seasons to get to the Wall, but there are only six episodes left in the series. Surely they'll have to move a bit faster if they want to get close enough to the living to destroy them? Otherwise we're looking at more jumps in the plot's timeline.

Will Sam ever give Gilly credit for her discovery?

We sure hope so. He is taking all the credit right now. He's a nice guy, so we hope he does. Gilly deserves this!

What exactly are Bran's powers? And what are the limitations? He didn't know Jon is legitimized by marriage, and couldn't access that moment until Sam told him about it.

So far Bran’s only said that he can see into the past and present, but it’s unclear how much control he has.

Until Sam told him about the High Septon's diary, for example, Bran has no idea that Jon is actually a Targaryen. But once Sam tells him about the annulment and marriage between Rhaegal and Lyanna, he can see the event and figures it out.

It's interesting to note that the more Bran knows, the more he can see. He is all-knowing, but he seems to need a little help to get access to things that might not come to his mind.
