Fans were quick to pour over the photos and have already deciphered a major spoiler in one particular snap which shows Queen Cersei (played by Lena Headey) and Jaime (Nikolaj Coster-Waldau) in the throne room.
At first glance it looks as though the siblings are standing united as Cersei sits upon the Iron Throne with Jaime positioned at her side.
But, one Reddit user is unconvinced by the knight’s show of support for his lover and sister.
User xpbso believes the first look image holds a major clue about the demise of Queen Cersei and how her life will be ended.
Jaime can be seen with a sword decorated with red jewels and gold bands on his hilt and fans are certain this is the weapon that will be used to kill the monarch.
The weapon has not be spotted for two series and was last seen when Joffrey (Jack Gleeson) used it to destroy a book he was given by Tyrion Lannister (Peter Dinklage) on his wedding day.
But the fact that Jaime is now wearing it hints it will play a very significant role to play in upcoming episodes.
The blade is also named Widow’s Wail, which further suggests he will use it to kill his widow sister.
Game of Thrones returns to HBO on July 16 and will air in the UK on Sky Atlantic on July 17.
