There will be power struggle between Jon and Sansa, says

Actor Kit Harington, who plays the role of Jon Snow on fantasy drama "Game of Thrones", says the squabbling between his character and step-sister Sansa Stark is going to get more intense in the season seven.
At the end of the season six, Snow and Sansa joined forces to successfully defeat Ramsay Bolton and reclaim their home Winterfell, reported Entertainment Weekly.
But Sansa is still in touch with Peter Baelish and their friendship is likely to affect the bond that Sansa shares with Snow.
"There is definite tension between them right from the first scene. 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."

Harington, whose character came from the dead in the last season, is happy with the way it has shaped up on the show.
"It's a nice change for me this season, he talks more, he's more sure of himself. He doesn't just know what he's got to do but he's more sure of what he's saying - whereas before there was always some fear and doubt. I've gotten to enjoy not just grunting.
