Jon Snow might be “dead” in “Game of Thrones” Season 6, but that doesn’t mean the show won’t explore where he came from. The most recent trailer for the hit HBO drama may have teased the popular R+L=J theory, which could explain who Snow’s parents are.

Many fans are hoping to see the theory play out in the infamous Tower of Joy scene this season. The scene takes place during King Robert’s (Mark Addy) rebellion, where the theory suggests Ned Stark’s (Sean Bean) sister, Lyanna Stark, told him a secret before she died in the final hours of the war. Some believe the secret could be that she had a baby boy, Jon Snow (Kit Harington), with Rhaegar Targaryen, and she entrusted Ned to protect her son from Robert, who would have killed the baby on the spot. It is believed that Lyanna and Rhaegar were in love and she was hiding in the tower with their child. But viewers were told that Snow is the child of Ned and an unknown woman he had met during the war.

The latest trailer showed a glimpse of a battle at about the one-minute mark, which fans on Reddit suggested could be the highly anticipated scene in Season 6. A soldier who appears to be wearing Targaryen armor is fighting a man who probably is in Ned’s army. In the books, Ned’s dreams were haunted by the last time he saw his sister. Before Ned got up to the tower, he and his men had a bloody battle with Targaryen kingsguards.

Bran (Isaac Hempstead-Wright) will return in Season 6 and he is expected to be learning how to master his visions. The young Stark could then be able to connect the past and the present, which means the flashback to Robert’s Rebellion could be through his eyes.

In an interview with Entertainment Weekly in December, Wright said Bran will be learning to control his visions. Bran’s vision could make him a key player in the coming Great War.

“Now we’re given looks into very important events in the past, present and future of this world, and Bran is beginning to piece them together like a detective, almost as if he’s watching the show,” Wright dished.

“Game of Thrones” Season 6 premieres on HBO on Sunday, April 24, at 9 p.m. EDT.
