'Game of Thrones' season 7 spoilers news: Jaime's motivation for killing Cersei could be 'a little more subtle'

While most "Game of Thrones" theories suggest that Jaime (Nikolaj Coster-Waldau) will end up killing his sister/lover Cersei (Lena Headey) because of her endless hunger for power, a new fan theory suggests that Jaime will do it for some less obvious reasons.

The upcoming struggle between Jaime and Cersei is one of the "Game of Thrones" storylines that fans are looking forward to most in season 7. In the season 6 finale, Jaime returned to King's Landing to find Cersei being crowned the new leader of Westeros. When Jaime finds out that she got there by obliterating her enemies with wildfire, indirectly triggering the suicide of their last living child Tommen (Dean-Charles Chapman), it can only be assumed that he will not take it well.

In a recent post, a Reddit user suggested that, aside from Cersei's growing madness (resembling that of the "Mad King" Aerys Targaryen, who Jaime killed), a series of transgressions will be the reason Jaime turns on Cersei.

"Many people theorize that Jaime will end up being the valonquar because of Cersei's Mad King antics," the Redditor wrote. "However, I think his reasons will be a little more subtle than that."

"I feel that Cersei, intentionally or not, is marginalizing and alienating Jaime in a way that will destroy their relationship forever," he added.

The Reddit post laid out the numerous instances in which Jaime had been marginalized, mostly by Cersei. For example, he had to keep his children's true parentage a secret, which meant that he was never able to become a father to them.

In addition, Cersei didn't inform him that her trial by combat had been killed off, she left him out of all her plans in King's Landing, and she named Qyburn the Hand instead of him.

Previously, Cersei had been unsympathetic when Jaime lost his hand and unaffected when Tommen booted him out of the Kingsguard.

Could all of these various disses drive Jaime to confront Cersei? Will he be the one to put an end to her madness?

All these questions will hopefully be answered when "Game of Thrones" season 7 debuts next year.
