Warning: The follow article contains season six finale spoilers.

The Starks have ended Game of Thrones season six in control of Winterfell again, but a power struggle might already be brewing.

In season six finale 'The Winds of Winter', Sansa Stark (Sophie Turner) briefly showed a twinge of unrest when her half-brother Jon Snow (Kit Harington) was crowned King in the North - and thus became her family's de facto leader.

"[The conflict], I suppose, really at the heart of it is about dysfunctional families," Harington says in a newly-released HBO promo video.

Sophie Turner admitted: "There's always been tension between [Sansa and Jon] because, since they were little, Sansa has always looked up to her mother and always taken on her mother's views of everything. 

"Her mother really didn't like Jon because of… the whole affair thing. That doesn't mean that they don't love each other - it's just typical sibling tension."

"I think Jon is oblivious," Harington adds. "He hasn't actually learned his lesson of trying to pay attention to what [Sansa's] feeling. He says he has - but he's asking her to trust him. Not listening, watching and observing her, that could be a real problem for him."

Even Sophie Turner admits that Sansa is resentful of Jon claiming victory over the Boltons - since it was her call to the knights of the Vale that truly saved the day.

"[Jon's] named King in the North and she gets no credit for anything," Sophie notes. "Jon doesn't acknowledge everything his sister has done for him, after all that they've been through.

"It's not that she's looking for praise or anything. She did it because she wanted revenge (against Ramsay Bolton) and also because she wants her home back. Jon is so naïve, so Sansa's just a little bit agitated."

Uh oh. With Little Finger now firmly in Sansa's corner, could Jon be facing ANOTHER mutiny from a close ally?

Producers have also hinted in a video recap of the season six finale that the relationship between the Stark siblings "will be crucial to watch" going ahead.

We must now wait a year to find out if these two siblings can coexist, as Game of Thrones returns in 2017 on HBO in the US and Sky Atlantic in the UK.
