After seeing the "Game of Thrones" season 7 episode 2 trailer, everyone thought that Littlefinger was going to tell Jon about his true parentage, but the fight in the Winterfell's crypt wasn't related to Jon's heritage. Jon hates Littlefinger a lot, just like Eddard did, and that's all. A Rhaegar Targaryen's flashback in season 7 seems now more likely: Bran is probably the one who will figure out the truth about Jon Snow through one of his "time travels." Moreover, we have several clues that Rhaegar will be featured in the next episodes of season 7.

Devin Oliver to appear in 'Game of Thrones'

A few months ago, "I See Star's" lead vocalist Devin Oliver shared a photo of himself wielding a bow with striking "Khaleesi" blonde hair on Pinterest. The caption of his post reads: "I may or may not have made an appearance in Game of Thrones season 7." Shortly after, Devin Oliver replied to a fan who was speculating that he could be playing Rhaegar in "GOT" season 7. "My lips are sealed," was the singer reply.

Jon is totally going to know about his parents

It's clear that David Benioff and D.B. Weiss decided to include the Tower of Joy's flashback for a reason (they stated once that they don't even like the use of flashbacks...).

Jon's true heritage is going to play a role in the "Game of Thrones" finale, so Jon needs to know about Rhaegar sooner or later.

Bran likes to time travel

In the first minutes of the Season 7 premiere we saw the White Walker's army marching towards The Wall, then Bran recovering from one of his mind travel. It looks pretty clear that the young Stark is going to time travel again. He's the Three-Eyed Raven now. That's what he is supposed to do.

What 'Awayforthelads' wrote on Reddit

Warning: potential spoilers ahead!

The well-known leaker "Awayforthelads" wrote on Reddit a while ago about a flashback featuring Lyanna and Rhaegar in Season 7. "There will be a flashback scene to Rhaegar and Lyanna's wedding", wrote the leaker on Reddit.

And a flashback about Lyanna and Rhaegar's wedding would be meaningful: if they married one another, Jon is not a bastard anymore.

Although we cannot say for sure that Devin Oliver/Rhaegar Targaryen will be featured in the next episodes of the show, a Rhaegar's flashback looks plausible. Brace yourselves, "GOT" fans: this might be the best season so far!

"Game of Thrones" season 7 episode 3, titled "The Queen's Justice," will air on July 30, on HBO.
