The world of "Game of Thrones" is filled with dangerous characters who could easily kill their enemies without breaking a sweat. But is it possible that the deadliest person in Westeros is the one who isn't trained in combat? Some believe that Sansa Stark is set to be the most feared character in "GoT" Season 8 after she betrays not just Jon Snow, but her own sister Arya as well.

Sansa Stark vs. Arya Stark

The seventh season of "Game of Thrones" has already offered a glimpse at the tension between Sansa and Arya. After discovering that her sister sent a letter to their brother Robb Stark, Arya seemed convinced that Sansa has betrayed their family.

Needless to say, it didn't sit well with the younger sister who decided to confront the current Lady of Winterfell.

Although the conflict was actually orchestrated by Littlefinger and it was later revealed that the two sisters were playing him all along, the idea of the Stark girls fighting was a touchy subject for "Game of Thrones" fans. Some speculate that Sansa is truly wary of Arya and looking for a way to get rid of her in the final season. However, Arya Stark might not be the only one Sansa will betray.

Will Sansa Stark betray Jon Snow for Winterfell?

There is speculation that Sansa had actually decided to kill Littlefinger to gain the favor of the Northern lords gathered at the Great Hall.

The trial may have been staged to show she is not afraid to defend the North. Her actions are very different from Jon Snow, who had previously decided to spare the Karstark children despite Sansa's firm advice in the premiere of "Game of Thrones" Season 7.

So, is Sansa Stark hoping to get rid of both Arya and Jon Snow so she can remain the Lady of Winterfell?

At the moment, Sansa's motives are still unclear. Hopefully, new details will be revealed about Sophie Turner's character once the final season begins filming.

Let the final 'Game' begin

Liam Cunningham, who portrays Davos Seaworth in the series, has recently confirmed via NME that filming will start this October. The actor stated that production will take more time because the episodes for the final season will be much longer.

Production might begin soon but that doesn't mean that the final season will premiere next year. Liam Cunningham stated that the cast and crew will continue working until summer of 2018. Unfortunately, this means that "Game of Thrones" Season 8 will air on HBO by early 2019.
