“Game of Thrones” Season 6 has taken a unique approach to time-travel back into the past and revealed important details of the Westeros saga through Bran Stark’s (Isaac Hempstead Wright) visions and the Three-eyed raven (Max von Sydow). Now, fans are expecting that the show is all set to reveal Jon Snow’s (Kit Harington) parentage among a lot of other things.

[Spoiler Alert] “Game of Thrones” Season 6, episode 3, “Oathbreaker,” showed young Ned Stark (Robert Aramayo) travelling to the Tower of Joy with six of his men, including Howland Reed, to defeat three Targaryen guards. It is presumed that Ned was going to save his dying sister Lyanna Stark (Cordelia Hill). Unfortunately, the Three-eyed Raven decided to keep viewers waiting and brought back Bran from his trip.

Before going into details of Jon Snow’s parentage, it is important to know the history first to make things easy. The time where Bran’s visions took him to, Aerya Targaryen (the Mad King) had the Iron Throne. His son Rhaegar Targaryen was married to Elia Martell. However, Rhaegar fell for young Lyanna Stark and the two ran away.

Lyanna was then bequeathed to Robert Baratheon, who lost his cool after learning about Rhaegar’s misdoings. He rebelled, along with Ned Stark, and overthrew the Mad King. Ned eventually found out where Lyanna was and went to get her back. Lyanna, before dying, bore a child and this is where the popular R+L=J theory takes effect.

Fans believe that Jon Snow is the son of Rhaegar Targaryen and Lyanna Stark. In order to protect the baby from enemies, Rhaegar ordered his best fighter Ser Arthur Dayne to guard the Tower of Joy. “Oathbreaker” also revealed that Dayne was not killed by Ned, as the world had known, but was actually stabbed from behind by Reed.

Fans believe that Lyanna made Ned promise never to reveal Jon Snow’s true parentage and raise the child as Ned’s own. In order to keep Snow’s parentage a secret, Ned even went to the extent of lying to his wife that he cheated on her while he was away on battle.

If R+L=J theory is proved right, that would mean Jon is a Targaryen and a rightful heir to the Iron Throne. This would also prove Melisandre’s (Carice van Houten) theory that Jon Snow is “Azor Ahai,” or the Prince That Was Promised, and not Stannis Baratheon (Stephen Dillane). Now that Jon has left Night’s Watch, free of his oaths and duties, he can very well go and claim the Iron Throne.

His oath of “wear no crown and win no glory” is over as he is no longer tied to Watch for life. This is because technically he died and that makes him free from his oaths. Moreover, he had previously broken his oath by getting intimate with Ygritte (Rose Leslie).

“Game of Thrones” fans may know a great deal about Snow’s parentage in episode 5, titled “The Door,” because the episode description states “Bran learns a great deal.” Fourth episode, “Book of the Stranger” will return on HBO on May 16.
