Game of Thrones season 6, episode 3 preview: Will 'Oathbreaker' deliver another revelation?

Does this preview of Game of Thrones' upcoming episode potentially hint at one of the show's greatest mysteries finally being solved?

*WARNING* MAJOR SPOILERS FOR GAME OF THRONES SEASON 6, EPISODE 2*

The latest episode's monumental final reveal has made it clear nothing in Westeros will ever quite be the same again; Jon Snow is alive, and he will drench the snow of Night's Watch red with vengeance.

Though fans may still be recovering from Snow's resurrection, others may already be looking forward to what exactly his return means for the show's narrative; with the preview for episode 3, titled 'Oathbreaker', potentially providing some small clues.

Clearly, the next episode will need to deal with the immediate aftermath; with the teaser opening on Tormund Giantsbane's words that Snow's miraculous resurrection has led some to consider him a "god".

Will the Lord Commander become fixated on seeking vengeance against the Night's Watch brothers who killed him? Or, now that his vows to serve the Watch have effectively ended with his death, will he instead turn immediately to the matter of taking on Ramsay Bolton's villainry?

We then see a continuation of Arya's training and Daenerys' journey to Vaes Dothrak; yet, the most intriguing part of the teaser glimpses at another of Bran's flashbacks, which looks to be a scene of a young Ned Stark battling Targaryen guards.

Which, in turn, has led many to believe this is the rumoured Tower of Joy scene; a historical event in Westeros' history, in which Stark defeated Prince Rhaegar Targaryen's guards in order to rescue his younger sister Lyanna (who we've already seen in episode two's flashback).

A moment potentially crucial to one of the series' greatest mysteries: the question of Jon Snow's parentage. Many fans believe Lyanna actually fell in love with her captor Rhaegar, and bore him a son; by the time Ned Stark finally reached her, she was dying during a troubled childbirth, begging her brother to pretend the child was his own.

And that child? None other than Jon Snow. Indeed, it would seem a fitting development for Snow's epic return; with the character discovering the truth of his own past becoming an essential factor in his reclamation of his own identity and his rightful place in Westeros.

Game of Thrones airs on Sunday nights in the US, at 9PM on HBO; and will be simulcast at 2AM on Sky Atlantic in the UK.
