“Game of Thrones” Season 6 will be filmed at new locations this year in Spain. One of the locations could be the place where a flashback scene may be filmed, and it's expected to confirm the fan theory R+L=J.
The identity of Jon Snow’s mother has always been a subject of debate among fans. Although Ned Stark (Sean Bean) has spoken about Jon’s mother, fans came out with a theory about the character based on Ned’s personality and what some of the other characters have said about the issue. The theory R+L =J states that Jon is the love child of Rhaegar Targaryen and Lyanna Stark.
Jon is said to have been born in the Tower of Joy, where Rhaegar kept Lyanna after supposedly kidnapping her. According to a report by WatchersOnTheWall, the new filming location of Castillo de Zafra looks very similar to the Tower of Joy.
Britt Hayes of ScreenCrush also believes the new location will be used as the Tower of Joy for a scene in “Game of Thrones” Season 6. The characters Rhaegar and Lyanna have not been seen in any episodes that have aired so far, but have been repeatedly mentioned right from the first episode of the TV series.
The flashback scene that may be featured in the next season could be the birth of Jon Snow, during which Lyanna is said to have died. According to the books by George R.R. Martin, Lyanna had made her brother Ned promise something before her death, and the fans believe it to be the secret of Jon’s parentage.
Hayes points to a recent casting call for the role of a “legendary fighter,” who is known for being a “paragon of knighthood,” and speculates this to be Ser Arthur Dayne. In the books, Dayne was one of those guarding Lyanna at the Tower of Joy. Hayes also predicts that the inclusion of the flashback scene in “Game of Thrones” Season 6 will mean the return of Jon Snow eventually.
