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

Warning: Spoilers for "Game of Thrones" season seven episode six, "Beyond the Wall." If you aren't caught up on the series, read at your own risk.

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 peak 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 storyline 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 storyline 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 off-screen.

Arya and Sansa probably have something bigger planned and this sister fight is 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 actually sparring, then why is this even happening? Why can't these sisters accept their differences, the fact they are both somehow alive, and have a long dinner to catch up on their traumatizing experiences? Geeze, 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 is 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 possible that it's 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?
