Whoa. What? Carrying on the theme of 'but...he/she is dead?' characters, Sibel Kekilli shocked onlookers as she rocked up to the Game of Thrones set in full costume ready for filming Season 6. Not only is she supposed to be dead (we even saw the body) but her purpose has been served. There's no real reason for her to make a comeback, and that's what has led fans to believe there are several flashbacks in the upcoming season. Again though, her relevance to the story is sketchy, so when she does appear, everyone is going to be in the dark.
