Game Of Thrones: What Is Behind The Door?

On Friday, HBO released the synopsis for the fifth episode of Game of Thrones Season 6, titled "The Door." It is a cryptic and peculiar title that doesn't tell us much however, piecing together some information we know about tonight's episode, "Oathbreaker," and from the source material could give us a clue.

We from the preview video that tonight's episode of Game of Thrones will show the Raid on the Tower of Joy, a key moment from the history of Westeros. The battle will be seen through the visions of Bran and the Three-eyed Raven.

If we look at the synopsis for "The Door," a portion of it reads, "Bran (Isaac Hempstead Wright) learns a great deal." What Bran stands to learn inside the Tower of Joy is perhaps the biggest deal in all of Game of Thrones. This title and synopsis make us wonder if "Oathbreaker" will end after seeing the Raid on the Tower of Joy, but before Ned actually opens the door to the Tower, saving that reveal for two weeks later.

Another possibility has to do with Daenerys Targaryen. She is not mentioned at all in the episode's synopsis, but there is a significant door in her past. While it has never been mentioned in Game of Thrones, in the A Song of Ice and Fire novels on which the series is based, Daenerys remembers spending her earliest years in a large house with a red door in Braavos. It was there that she grew up in the care of Ser Willem Darry, the knight who smuggled her and Viserys off of Dragonstone at the end of Robert's Rebellion. However, when Darry died, the servants turned on them, looting the house and leaving Dany and Viserys on the street.

In the books, the House with the Red Door has taken on great symbolic meaning for Daenerys. She remembers it as a simpler time, and as the closest thing she's ever had to a home. Even as she rules over Meereen, she still dreams of the red door.

As we stated, the house with the red door hasn't made its way into Game of Thrones yet, but the show has become somewhat fond of flashbacks. Perhaps as Dany is on her way to Vaes Dothrak to join the dosh khaleen, or after she has already arrived, she reflects on her childhood and we see the red door for the first time.

Game of Thrones airs Sundays at 9 p.m. ET on HBO.
