A "Game of Thrones" fan previously asked actress Maisie Williams for a selfie. In turn, the actress posted a face swap with her TV sister Sansa, resulting in a photo said to be an epic image.

The "Game of Thrones" actress posted a picture on Twitter and tagged @gameofmophie. The epic picture is said to pass as the cover of the final book of the "Song of Ice and Fire" written by George R.R. Martin. Williams was reportedly game enough to respond to a fan's request for a selfie.

In the picture she took, Williams swapped faces with Sophie Turner, who plays Sansa Stark on the American drama series from the book "Game of Thrones." The photo resulted in a Sansa family portrait that is said to make it look right at home hanging in the great grand halls of Winterfell. Moreover, the photo may be used on the battlefield for scaring off the Lannister armies, Time reported.

This was the second time that Turner and Williams have swapped faces. The two "Game of Thrones" co-stars are reportedly close friends as they appear to be all over social media. Moreover, the two came up with their own portmanteau that is Mopie, Digital Spy reported.

Meanwhile, after the death of Catelyn Stark in the third season of the "Game of Thrones," it is expected that the character would be returning in the form of Lady Stoneheart. With Stark missing in the Season 4 finale, it is speculated that she would appear in the Season 5 finale which did not happen either as well as in Season 6.

"Game of Thrones" is rumored to feature the comeback of a Lord Stoneheart version of Robb Stark. Richard Madden is rumored to play the role. However, Madden has been noted saying that he would rather just watch the show and see what will happen next. Michelle Fairley as Cat Stark will reportedly not return to the show as she was recently cast in the Starz original series "The White Princess."
