Will Jaime Kill Cersei On 'Game Of Thrones'? Episode 3, Season 7 May Have Hinted At It

Sunday's new episode of Game of Thrones was a game-changer for the Lannisters in a lot of ways. With Daenerys Targaryen's army finally descending on Westeros, the reviled royal family was able to masterfully avoid her attack and set up a killer alliance with the Ironborn. But there could be trouble brewing within the Lannister clan... as many fans picked up on in the new episode. Spoiler alert: This post will discuss events in Season 7 Episode 3 of Game of Thrones "The Queen's Justice." As the Lannister family continues to grow more powerful, fans are predicting this is the beginning of Jaime's destiny to kill Cersei on Game of Thrones.

This is a popular fan theory that's been around for a few seasons now, and it's also one that seems to hold the most water so far, especially after the events of last night's episode. It's becoming clearer than ever there's a growing wedge between Cersei and Jaime — not only is Cersei leading on Euron Greyjoy, the bloodthirsty pirate who openly mocks Jaime's relationship with her, but the queen is also starting to treat her brother-lover as more of a plaything than an actual romantic partner, no longer taking any precautions to hide their sexual relationship.

Viewers got another hint at Jaime's distance from Cersei's ever-growing cruelty in the final scene of the new episode when he mentions to Olenna Tyrell he had to convince his sister to allow him to poison Olenna instead of torturing her.

It definitely feels like the show is planting the seeds for a Lannister break up very soon, and may be on the way to confirming the popular theory that Jaime will be the one to kill Cersei. Basically, the theory first came up when Cersei received a prophecy stating she would die at the hands of "the Valonqar," a Valerian word for "little brother." Initially, fans assumed this was referring to Tyrion, but now our money's on Jaime, Cersei's twin who was technically born shortly after her.

The new episode gave even more validity to the theory by setting up the parallel between Cersei and the Mad King, Aerys Targaryen. Fans noticed the method of how Cersei killed Tyene Sand in front of her mother, Ellaria, was very similar to how Aerys forced Brandon Stark (Ned Stark's brother) to watch his father die while tied up. The Mad King met his end at the hands of Jaime Lannister, earning his nickname Kingslayer, so now that Cersei is being set up as a Mad Queen, the parallel might continue to her demise.

Pretty much every Lannister scene in this recent episode seems to point to this theory proving true, so don't expect any more Lannister love for much longer.
