Kit Harington recently discussed Jon Snow's relationship with Sansa Stark. "There is definite tension between them right from the first scene," Harington told EW. "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."

We will also see much more of Euron Greyjoy (Pilou Asbaek) in Game of Thrones Season 7. He will return with a new look and a new attitude. "He’s much more just f--king enjoying himself this season," Asbaek told EW. "He’s more charming. He takes himself seriously, but not too seriously."
