WARNING: This post contains spoilers.
Ian McShane has joined the GOT cast for Season 6, and as is normal when a new member joins the cast, speculation abounds. We don’t yet know who he’s playing, but he has hinted that his character is “bringing somebody that you think you’re never going to see again.”
That’s pretty ominous. One likely candidate that McShane’s character could bring back is Catelyn Stark as the pseudo-undead Lady Stoneheart, the mysterious and vengeful wraith from book 4. Fan-website, Watchers on the Wall, has also speculated that it may be the Hound as well and actor Rory McCann was spotted on set in Belfast even though he was presumed dead in Season 5. Of course, just because an actor is on set does not mean their character is “back.” They might just be in a flashback.
