Game of Thrones is returning with some of the biggest story elements the hit show has ever featured. The armies of the Night King have breached The Wall and are steadily advancing towards Winterfell (which just so happens to be where most of our remaining heroes are.)

But while it's easy to get lost in all the dragon and zombie wars that are coming, there are still a couple of unresolved plot threads that we need to see finalized. These are five questions that we need Game of Thrones Season 8 to answer.

The Fate Of The Greyjoys

Playing a relatively small part in the War of the Five Kings, Theon and Yara Greyjoy were set to play a large role in the final season, fighting alongside Daenerys Targaryen. But following a sneak attack by their uncle, Euron, in Season 7, their forces were depleted and Yara was captured. Theon ends that season setting out to sea alongside a handful of soldiers from the Iron Islands. Their mission is to find Yara and recuse her from Euron.

The Greyjoys are fairly divorced from the rest of the events happening in Westeros. It's not hard to imagine their story falling through the cracks as events shift more to focus on the fate of Winterfell. But we're hoping we get to see Theon (hopefully) finally redeem himself, at least in the eyes of others. His narrative arc has seen him turning towards noble intentions, and seeing the completion of his arc would justify the time we had to spend with Reek.

Gendry's Right To The Throne

The discovery of Gendry in Season 1 was a quietly monumental moment for Game of Thrones. Ned Stark discovered that the reason the former Hand of the King, Jon Aryn, had died was because he had learned of the Baratheon bastards, Gendry being one of them. Gendry in particular could prove to be the rightful heir to the throne, especially over someone like Joffrey. This puts Gendry in a very advantageous position, especially after making allies with people like Jon Stark.

But what happens if Daenerys finds out? The Mother of Dragons could see him as a genuine threat to her bid for the Seven Kingdoms. And, unlike Jon, she doesn't have a personal connection to him that could alleviate some of the tension if and when she finds out Jon also has a claim to the throne. Gendry is even the son of the man that murdered her family. She might burn first, talk later if she were to find out. After managing to defy the odds and survive in Westeros, we need to know if Gendry will be the spark that sets off a powder keg.

Melisandre's Prophecy

Melisandre left Westeros during Season 7, heading back to her homeland. But before she left, she gave Varys a foreboding warning: "I will return, dear spider. One last time. I have to die in this strange country, just like you." Part of what makes this so foreboding for Varys is that he's a man who believes in things he doesn't understand. He said as much to Tyrion back in Season 3 while talking about the man who mutilated him to make an offering to a dark god.

So, we know Melisandre will return at some point because she still has to die in Westeros. But will she be coming alone? She isn't the only priestess out there who serves the Lord of Light. Daenerys met one while ruling in Meereen who said she would preach of Dany as the chosen one to protect the world. Will Melisandre come with a full force at her back? Could they be as powerful as her, if not more so? We need to know how this prophecy works out.

What Does Qyburn Know?

When the assorted power players assembled in the dragon pits at the end of Season 7, most of the cast was introduced to the effects of the White Walkers for the first time. Jon Snow brought back a reanimated corpse to scare everyone into an alliance while he was beyond The Wall. While most of the people present recoiled in fear at the sight, Cersei's resident mad scientist and current Hand of the King, Qyburn, looked like he was in love.

Qyburn has always been fascinated by death. His experiments have led to monstrosities like the Mountain becoming whatever he's transformed into. Now, seeing a purely magical source of that kind of power, it's not hard to imagine Qyburn picking up some new ideas and conducting some new experiments. But we need to know if these actions could help save Westeros or play a part in bringing about the end of the world. He could even be the real source of the Clegane Bowl.

The Valonqar

One element of the original books that was only partly translated to the television show was the prophecy a young Cersei heard about her fate. The soothsayer Maggy the Frog told her: "You'll never marry the Prince, you'll marry the King. You'll be queen, for a time. Then comes another, younger, more beautiful, to cast you down and take all you hold dear. The king will have 20 children and you will have three. Gold will be their crowns, gold their shrouds." The prophecy has mostly come true so far, and could even still apply to the arrival of Daenerys.

But the part of the prophecy that was in the books and left out of the show centered around Cersei's final fate. "And when your tears have drowned you, the Valonqar shall wrap his hands about your pale white throat and choke the life from you." The Valonqar is a Valyrian term for younger sibling, meaning Cersei is prophecized to either be killed by Tyrion or Jaime. So, we want to know why that part of the prophecy was left out of the show? Will it indeed be the Valonqar that kills her?

We'll hopefully find out the answer to all these questions (and plenty more) when Season 8 of Game of Thrones premieres Apr. 14. The HBO drama stars Peter Dinklage as Tyrion Lannister, Nikolaj Coster-Waldau as Jaime Lannister, Lena Headey as Cersei Lannister, Emilia Clarke as Daenerys Targaryen, Sophie Turner as Sansa Stark, Maisie Williams as Arya Stark and Kit Harington as Jon Snow.
