Leaked images show Jon Snow's return on Game of Thrones season 7 set

Kit Harington was finally spotted in Belfast, Ireland amid the filming for Game of Thrones season 7. Many actors were seen in the city in last few days but this is the first instance when the actor, who plays the iconic character of Jon Snow, was captured in the city.

Harington was spotted with Sophie Turner's body double and the pictures were posted on the English actor's Facebook fan page. In another set of on-set images, the actor appeared in wearing a costume while holding a set of papers, probably trying to rehearse the dialogues.

The sighting of Jon Snow's character during summer is interesting considering the fact that season 6 ended with Winterfell wrapped up in a white blanket of snow. Fans are intrigued to know why the King of The North is wearing casual royal costumes and is in roaming in summer.

The last season gave a hint of a prolonged winter that might encourage the advancement of the White Walkers in Winterfell. In one of Bran Stark's visions, they were also spotted destroying the Wall and attacking the army of the Night's Watch. It remains to be seen, how the newly crowned King of the North will protect its people and allies from the greater threat that is looming close.

Show creator, David Benioff, and Dan Weiss has previously said that the crew will film late till winter in order to show the after-effect of the longest winter that has arrived in the realm.

The sixth season of the epic fantasy series by HBO ended on a significant note where each major character taking the lead of their realm as they prepare themselves for the upcoming storm that is awaiting them in the upcoming season.

The multiple story arcs of the blockbuster series have led many to believe that once the series gets over after its eighth season, HBO will come up with a spin-off.

The network programming chief weighs in on the theory but maintains that meticulous planning and detailing is needed for another series like GoT. "There are so many properties and areas to go to. For us, it's about finding the right take with the right writer," HBO programming president Casey Bloys told The Hollywood Reporter.

"You're getting them right when they're about to embark on production. It's a big, big commitment for them, not just their creative force, but also their family life. They're gone for months at a time. So it's a big, big thing. But should we find a property that makes sense as a spin-off or a prequel — whatever you want to say — I would not expect them to do it, because they're going to need to decompress for a good amount of time, but it would certainly be nice to have their involvement in some way. At what level? I have no idea."
