Sophie Turner Talks Sansa's Fate In 'Game Of Thrones'

According to reports, Turner and Hill seem to hint something big in the upcoming Season 7 and Season 8 of "Game of Thrones". The two cast members spilled few yet important details that fans should keep an eye on when the series return.

In Turner's interview with HeyUGuys, the actress indirectly reveals her appearance in the last and final chapter of "Game of Thrones". As she talks about her filming projects for "X-Men" and for other movies, the 20-year-old star mentions her GoT stint.

"We're about to start shooting the next X-Men, we've just finished shooting Season 7 of [Game of] Thrones, and I've got a couple of movies to do before X-Men starts," says Turner. "And then we go on to Season 8."

In previous reports, it is said that Sansa will take a darker road in "Game of Throne" Season 7. Not to mention the speculations that she might betray her brother, Jon Snow (Kit Harrington).

Though there is no confirmation of this theory, the actress says that her character will have major changes in the upcoming seasons. The actress reveals the wonders behind Sansa's first kill (Ramsay); whether she like it or not, what is certain "she definitely is a lot more powerful" now.

Conleth Hill Reveals Possible Alliance

Meanwhile, in Hill's interview with the Huffington Post, the actor somewhat opens another theory that might happen in the last two seasons.

As per his interview, he reveals the possibility of another alliance between Littlefinger (Aiden Gillen) and his character, Varys. The site asked the actor whether the fans should keep an eye on these two characters or not.

"I can tell you that I loved working with Aidan Gillen (Littlefinger), and I can tell you that it's possible we work together again," says Hill before adding, "But not definite."

For starters, "Game of Thrones" is a predictable yet still surprising story. There might be leaked spoilers surfacing on the internet but what is certain so far is the Daenerys (Emilia Clarke) and Snow's meetup.

"Game of Thrones" season 7 returns some time later this year.
