Fans have been absolutely on the edges of their seats waiting for the Tower of Joy to make an appearance on Game of Thrones and finally reveal the mysteries that not even book fans knew the answer to. Sunday's episode, "Oathbreaker," promised to unearth those secrets. What's in the Tower of Joy on Game of Thrones? Despite how eager everyone is to find out just what went down at the Tower (even Bran), the show plays coy. Book fans are familiar with the scene thanks to Ned Stark's hazy flashbacks to it, but show fans haven't gotten an explicit look at the Tower before tonight. Unfortunately, it's similarly unrevealing.
The flashback is revealed in one of Bran's visions of the past, but it's cut short by the Three-Eyed Raven, who insistently stops Bran every time he tries to get into the Tower to see what's going on. Bran is allowed to see a younger version of his father, Ned, arrive with his band of knights to fight the remaining members of the Targaryen kingsguard as he tries to rescue his sister, Lyanna. Lyanna had been abducted (or ran off with) Rhaegar Targaryen, who had just died by the time of the flashback.
The Tower of Joy is such an important moment because it reveals a few key things, including Lyanna Stark's fate and the promise she made Ned swear before she died. Fans have come to believe that promise concerns Jon Snow; namely, that he is Rhaegar and Lyanna's son and that she was begging Ned to protect him. Understandably, this revelation would be a pretty huge moment that would change everything for Jon and introduce a new potential player in the fight for the throne. However, since it's such a big secret to uncover, the show is stretching out the tension just a little bit longer.
Bran was as desperate as anyone else watching to see what was waiting in the Tower – presumably Lyanna, but who knows who else? He even called out to Ned, who seemed to hear him somehow. I think all of us watching were Bran in that moment; just show us what's going on up there, Game of Thrones!
Sadly, we don't get to see and neither does Bran. He's pulled from the vision by the Three-Eyed Raven just as he's about to follow Ned up the steps. The only clue coming from the Tower of Joy itself is a ragged scream that sounds like a woman's voice. Could that be Lyanna giving birth to Jon? You're not going to get any answers from "Oathkeeper," and neither will Bran.
