Jon Snow will soon reunite with an old foe Theon Greyjoy in the upcoming "Game of Thrones" Season 7. Latest photo stills from the HBO show's Spanish filming site teased of a potential violent reunion between the two characters.

"Game of Thrones" Season 7 is expected to feature several reunion scenes between family members, friends and even old enemies. It appears that one of these scenarios will include a meeting between the new King of the North and the Greyjoy prince. On-set photos posted on Daily Mail revealed cast members Kit Harington and Alfie Allen filming Jon and Theon's tense encounter in Dragonstone.

Portrayed by Harington, Jon appears furious to find the man who betrayed the Starks arriving on the shores of Daenerys' (Emilia Clarke) new home base. Some of the on-set images revealed Jon's aggression as he grabbed Theon (Allen) by his coat and dragged him away from other soldiers.

Theon has committed several transgressions against Jon and the Stark family as shown in earlier seasons of the HBO show. After seizing Winterfell for himself, he was unable to protect it until the stronghold landed under the deceased Ramsay's (Iwan Rheon) control.

Despite the Greyjoy prince's reformed ways and his role in Sansa's (Sophie Turner) escape, Jon has yet to forgive Theon for his past actions. It appears that the said character also harbors feelings of regret and shame given his cowardly reaction to Jon's violent Dragonstone welcome.

In other news, "Game of Thrones" may be heading to Sweden to film some of its scenes on the island called Gotland. Olivia Munck, executive producer and founder of The Line Gotland, shared in an interview with Swedish publication The Local that HBO representatives made some inquiries about a certain location in Sweden.

The company, a local firm that partners with TV and film productions, sent HBO several pictures of the town called Visby, as well as Gotland island, according to Munck. The photo requests started in August with showrunners requesting for several more pictures of the Swedish location.

However, the HBO series' showrunners have yet to give their feedback to The Line Gotland. Munck stated, "The last pictures were sent a few weeks ago. So we're waiting to see what will happen."

"Game of Thrones" Season 7 is expected to premiere in summer 2017 on HBO. Watch the final scenes of the Season 6 finale below:
