Someone is coming back in the fourth season of "Game of Thrones". Lady Stoneheart will make her return soon in the hit TV miniseries. Actress Lena Headey, who plays Cersei Lannister on the popular "Game of Thrones," dropped some spoilers on her Instagram feed for the fans of the show.

Lena Headey posted a photo on her Instagram feed suggesting what fans should anticipate in the next few weeks. The photo showed several stones arranged in a shape of a heart. Fans who have read the book already know what the actress meant.

However, for those who only follow the TV series, it means that Lady Stoneheart or Catelyn Stark will reappear from the grave through some magic or supernatural means. Catelyn will transform into the new persona of the vengeful Lady Stoneheart and will lead the Brotherhood without Banners to a vengeful path.

Lady Stoneheart will hunt down everyone she feels responsible for the downfall of the House of Stark as well as the crime that happened at the Red Wedding. Lady Stoneheart's reappearance was hinted to happen before the season finale of the "Game of Thrones" season 4.

However, since Lena Headey is already dropping hints, many think that Catelyn will be shown in this week episode.

This is not the first time that Lena Headey left some hints for the fans of the series. Prior to Sunday night's episode airing on HBO, Lena posted a photo of Pedro Pascal and herself. Lena's thumbs were being shoved into Pascal's eyes. This proved the ultimate fate of Pascal's character, Oberyn Martell, in the show. Oberyn's head was crushed by Gregor "The Mountain That Rides" Clegane during their fight. Oberyn is fighting for Tyrion's side after Tyrion's allies diminished.

"Game of Thrones" season 4 airs every Sundays at 9 PM ET on HBO.
