WARNING: This article may contain spoilers for the upcoming season of ‘Game of Thrones.’ Proceed with caution!

Since the Season Five finale of ‘Game of Thrones,’ everyone has been talking about Jon Snow. Though the Lord Commander of the Night’s Watch may have met his demise, we’ve been hearing rumblings about actor Kit Harington being on set for season six of the acclaimed HBO fantasy drama. But now regardless of the fate of the character, new reports are talking of a certain flashback being filmed right now that may unlock some Snow secrets.

According to Watchers on the Wall, the production is currently shooting at the Castillo de Zafra in Spain, which is presumed to be the show’s Tower of Joy. If the location doesn’t ring a bell (because you didn’t read the books), the events that unfold there involve Eddard Stark and his allies saving his sister Lyanna from Rhaegar Targaryen.

Fans suspect that this scene will finally reveal Jon Snow’s true lineage. Two unnamed actresses have been spotted on set with one lined up to play Lyanna Stark. The other can possibly be Ashara Dayne, sister of Arthur Dayne, or Wylla, the wet-nurse to Arthur and Ashara’s brother and someone who is frequently thought to be Snow’s real mother. It’s definitely possible that we could learn the truth when this episode rolls around.

And though this is described as a flashback, there will be a twist when it makes the jump from the page to the screen. It’s being said that rather than a simple cutaway sequence, Isaac Hempstead-Wright’s Bran Stark will be present at the Tower of Joy and the events will unfold before his eyes as a vision from the Three-Eyed Raven. And while that all sounds good, I’m more curious to know what Bran does with this information after he learns it because it has the potential to be game changing.

What do you think about ‘Game of Thrones’ visiting the Tower of Joy? Are you excited to see what unfolds in Bran’s vision? And do you hope that we learn who Jon Snow’s real mother is during these events? Sound off in the comments below.
