Another dead character could show up anytime in ‘Game of Thrones’ season six.

Sibel Kekilli, who took on the role of Shae in the first four seasons of the HBO fantasy drama, was recently on set in Peñíscola, Spain.

The 35-year-old onscreen partner of Peter Dinklage, who portrays the well-loved Tyrion Lannister on the hit series, was first photographed within the area on Monday.

During this time, Kekilli had not been sporting a costume, only a regular black outfit, hence the speculations that she could just be paying a friendly visit to her former co-stars.
However, later in the day, ‘Game of Thrones’ fan site Direwolves and Dragons reported that the actress has been staying in the hotel exclusively for the show’s cast members.

“Shae , sibel kekilli is here in peniscola and has been escorted onto set- tyrion hunger flashback?pic.twitter.com/hRTX4HCnO4,” the fan site stated on their official Twitter account.

Rumors that Kekilli will be making an appearance in the sixth season were further sparked by the fact that she was photographed on set wearing clothing similar to the costumes worn by the people in Meereen.

Although Shae’s appearance next season is now certain, the show’s approach for her character’s return remains unclear as she had already been killed off in the season four finale.

Following Tyrion’s escape, thanks to his brother Jaime (Nikolaj Coster-Waldau) at the end of such season, he bought himself some time to visit his father Tywin's (Charles Dance) room with the intention of killing him.

Although Tyrion did not immediately find his father there, he spotted Shae lying in Tywin’s bed decked out in the golden chains he gave to her as a gift. When she attempted to hurt Tyrion with a knife, the little Lannister grabbed the chain and used it to squeeze the life out of his former lover.

Terrified at what he just did, Tyrion silently made an apology to Shae's corpse. At that moment, he took his dead nephew Joffrey's (Jack Gleeson) crossbow and proceeded to killing his father in the privy after the head of House Lannister called Shae a "whore" a number of times.

With Shae’s death, Watchers on The Wall reported that the character could return as "a vision, a hallucination or a memory in Tyrion's mind combined with the sight of a Meereenese woman."

‘Game of Thrones’ season six is set to premiere on HBO in spring 2016.
