Winter will finally arrive in Westeros this season, but it looks like the remaining Starks will have another enemy to worry about.
While speaking with EW, Harrington revealed that Jon and Sansa's tension will increase this season, and that their relationship could take a dark turn.
"There is definite tension between them right from the first scene," Harington said. "There are the same problems — she questions his decisions and command; he doesn't listen to her. But as far as where that goes or takes them or how dark it can get, we'll see. It gets past sibling squabbling, it gets into two people power struggling."
Sansa and Jon have never been very close, as she's never exactly trusted him, but that changed when the two rallied together to defeat Ramsay Bolton in Season 6. However, with Littlefinger in Sansa's ear, her trust could swiftly fade.
It's clear that Jon wants what is best for his people. He wants to save Westeros from the destruction being brought by the white walkers. It seems as though Sansa could have other plans.
Is she going to make a play for Winterfell? We'll find out when Game of Thrones returns to HBO on July 16.
