The 9 biggest questions after this week's 'Game of Thrones'

This week's action-packed episode of "Game of Thrones" set up a gloomy future for our heroes (and villains) in Westeros. The Night King has a dragon now, making his army of the dead an even bigger threat than ever.

In between the battle for the living beyond the wall, the Stark women can't get along in Winterfell, thanks to Littlefinger and his obsession with creating chaos.

Based on developments in the story this week, and the brief peek at the season finale from the trailer, we have some burning questions that will keep us awake at night.

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

Are Sansa and Arya playing Littlefinger?

The entire point of Arya's story line in season six is that she isn't — and can never be — no one. She is loyal to her family and always will be. Her story line with the actress in Braavos also proves that she still cares about innocent people. This was also the point of her scene with Ed Sheeran and the young Lannister soldiers in the season seven premiere: Not everyone deserves to die for where their loyalties lie, because not everyone has a choice.

Sansa has spent most of her time on this show in Littlefinger's shadow, minus her time alone with the Boltons. She knows him more than she's letting on. It's also possible that Bran has told his sisters what he knows about Littlefinger.

Arya and Sansa probably have something bigger planned, and this sister fight could be a trap for Littlefinger. It's important to note that while it appears Arya and Sansa were alone during both of their intense conversations this week, one took place outside, and one in a bedroom with the door open. Littlefinger could be lurking anywhere, pleased to see his schemes playing out.

If Sansa and Arya are sparring, then why is this even happening? Why can't these sisters accept their differences and the fact they are both somehow alive and have a long dinner to catch up on their traumatizing experiences? Geez, ladies.

What does Cersei have planned in King's Landing? Surely she won't welcome her enemies without a fight.

Cersei has a thing for wildfire, and she's about to welcome her enemies with open arms into a dragon pit in King's Landing. There is no way she plans on this meeting beginning and ending in peace. What tricks does she have up her sleeve? It's possibly more wildfire, and Jaime could stop her (by killing her) before it's too late.

It's also entirely possible that Tyrion and Daenerys have something bigger planned that even Cersei won't see coming, assuming they're in King's Landing to be nice.

Why do characters who are obviously not going to die (yet) keep almost drowning?

First Jaime, then Jon. Why jerk us around when we know they're not going to drown? Come on. Will one of our favorite characters actually drown sometime soon?

Who will succeed Dany? How will she break the wheel?

Tyrion brings up an interesting and game-changing question for the country's future: When Daenerys is queen, how will she determine a successor?

Tyrion suggests ways that don't have to do with bloodlines. The Night's Watch and the Ironborn elect their leaders, which would be an effective and fair way to break the wheel and hopefully do some good for Westeros.

How and when will Jon find out who his parents are (i.e., that Daenerys is his aunt)?

We see Jon in King's Landing facing Cersei in the season-finale teaser, which means he's even farther from Bran, who can tell him who he really is. When will Jon find out, and why do the writers keep preventing this from happening? A revelation seems within reach, but they keep teasing us with Dany and Jon's incestual flirtation.

Is Euron going to be pissed when he finds out Cersei is pregnant with Jaime's baby? Is Yara alive?

Theon's mission right now is to save his sister, Yara, from his Uncle Euron. But is Yara alive? If so, she's definitely not OK. We hope Theon can redeem himself and save her, but at this point, that's looking like a long shot. If he's successful, it will probably kill him.

In "Eastwatch," Cersei tells Jaime she's pregnant and willing to tell people he's the father. But there's a huge problem. Euron is loyal to Cersei because he thinks they'll get married when the war is over. But with Cersei carrying the child of another man, who happens to be her brother, Euron could turn on her.

Is Cleganebowl finally happening?

The Hound is heading to King's Landing, where his zombie brother, The Mountain, is serving Cersei. Will we finally get the showdown we've been waiting for?

When will the Night King get past the wall? How strong is zombie Viserion?

With the show's new and accelerated travel times, how long will it take the Night King to lead his army past the wall to destroy the living in Westeros? Does having a dragon help them in any way? Over the past few seasons, Jon has far out-traveled their army.

We're guessing that the zombie Viserion gives the Night King a huge advantage, but we're wondering what it can do. Does it breathe ice or fire? Blue fire? We aren't likely to find out until season eight, but we're looking forward to an epic battle of fire-breathing dragons and whatever Viserion breathes now.

Where are Sam and Gilly going?

In "Eastwatch," Sam and Gilly (and toddler Sam) leave the Citadel, heading north. But where are they headed, and when will they get there? Our best guess is Winterfell, but wouldn't they have arrived by now, considering the time jump this show makes? Given what Gilly and Sam know — although they don't know the significance — it would make sense for them to bump into Bran or Jon at some point in the near future.
