HE MAY have ghosted us for all of season seven, but Jon Snow's trusty pal is set to make a big comeback in the final episodes of Game of Thrones.
According to the show's visual effects supervisor, Joe Bauer, the direwolf Ghost will be "very present" in season eight.
"Oh, you'll see him again. He has a fair amount of screen time in season eight," Bauer told Huffington Post . "He's very present and does some pretty cool things in season eight."
He also revealed they did actually shoot one scene with Ghost in the last season, but that it had ended up on the cutting room floor.
In the scene, Jon Snow (played by Kit Harington) told his wolf to look after Sansa while he was away from Winterfell.
One of the reasons the wolves haven't had a lot of screen time in recent seasons (of the three original Stark wolves, only Nymeria and Ghost are still alive) is because they aren't that easy to work with.
"The direwolves are tough because you don't want to get them wrong, so we end up always shooting real wolves and doing a scaling trick with them, but the real wolves only behave in certain ways," Bauer said.
As the long wait between Thrones seasons continues, little teasers of information continue to be drip-fed to the public from the cast and crew.
Last month, Harington warned fans that many of us will be unhappy about what happens in the final season.
Speaking to MTV News, Harington, 31, listed a number of hit series such as The Sopranos, Breaking Bad and The Wire, which all had controversial endings.
"They all ended in a way that is never going to satisfy you," he said.
"I think a TV series that's spanned eight, nine years is an incredibly difficult thing to end … I think not everyone's going to be happy, you know, and you can't please everyone."
Meanwhile, Harington's co-star Nikolaj Coster-Waldau recently said that "all the pieces fit" together in the end.
Of the finale's script, he revealed: "I mean, when I read it … some of the parts of it I'd get, and other parts of it were just completely shocking and surprising."
He was meant to say something completely different.
