Jason Momoa had a great reunion with his Game of Thrones cast members in Belfast this week. The actor, who is gearing up for his next big release with Justice League, couldn't control his excitement and shared a series of images which may have spoiled a major secret for GoT fans.

The 37-year-old actor was happy to spend time with his former co-stars as he was photographed with Showrunners David Benioff and D.B. Weiss, actors Kit Harington, Kristofer Hivju, Rory Mccann, Liam Cunningham and others in a Belfast club.

"Unite the clans. 24hrs in Belfast GOT Super honored to once a part of this show. I love seeing all my friends and new ones @khivju your a f****ng legend Mad crazy love to Dan and David and Every one I saw I know u just started good luck with filming the greatest show in history have fun," he captions the post.

The Northern Ireland's capital is a vital part of the HBO fantasy blockbuster as major part of filming takes place there. And considering the long winter over the Seven Kingdoms in the show, it is logical that most of the crew will be in the city.

The presence of Hivju among other major casts probably solves a much deeper mystery about his character Tormund Giantsbane's fate.

The one twist that put viewers on the edge of their seats during Game of Thrones season 7 finale was the memorable dragon moment – when the Night's King wakes up Khaleesi's dead dragon son as a zombie and which later blew deadly blue flames and crumbled the Wall down that stood strong for hundreds of thousands of years.

The scene let many assume that Tormund and Beric Dondarrion who were guarding the Wall along with other Nightwatchers may have succumbed to the ice dragon's wrath.

To keep fans guessing about his character's fate, Hivju told Hollywood Reporter in August: "I honestly don't know. It doesn't look good, though, does it? ... Realistically speaking, if you're on top of an ice wall and it's many hundreds of meters tall... I was a competitive climber when I was younger, and that fall, I must say, it doesn't look good, man. It really doesn't look good."

The epic finale also saw Little Finger aka a Lord Petyr Baelish's execution by the Stark sisters, the end of the incest relationship between Queen Cersei and her twin brother Jamie Lannister and the shocking sex scene between "aunt" Daenerys Targaryen and her "nephew" Jon Snow.

Season 8 of Game of Thrones will have only 6 episodes and is expected to premiere in 2019.
