With production now under way onGame of Thrones Season 7in Northern Ireland, several casting rumors have started to surface from the set. One such rumor, involving 90-year-old small screen legendAngela Lansbury, has already been debunked. Today, another rumor surfaced that may confirm the return of two beloved cast members. Both of these actors were recently spotted arriving in Northern Ireland, which is the production hub for Season 7, so it seems likely their characters will return. If you aren’t fully caught up withGame of Thronesyet there will be SPOILERS below, so read on at your own risk.

The two actors in question areIain Glen, who plays Jorah Mormont, andJoe Dempsie, who plays Gendry. While we last sawIain Glen’sJorah Mormontin the fifth episode of Season 6, he never returned in the back half of the season. During his last appearance on the show, he revealed to Daenerys Targaryen that he has contracted greyscale, a disease that can prove to be fatal, which turns their skin hardened like stone, which is why those with greyscale are often called Stone Men. Daenerys ordered Jorah to find a cure for this disease and return back to her, which may be happening in Season 7.

Watchers On the Wall reports thatIain Glenwas spotted on an airplane to Belfast in August, alongsideGwendoline Christie(Brienne of Tarth), and earlier this week, a fan posted a picture she took with the actor in Belfast. Since most expected Jorah to return at some point, this news isn’t terribly surprising, but the return ofJoe Dempsieas Gendry is quite a big revelation, since he hasn’t been seen on the show since Season 3.

Joe Dempsieappeared in 17 episodes over the first three seasons ofGame of Thrones, and he was last seen in the Season 3 finaleMhysa. Gendry, a skilled blacksmith, was identified by Ned Stark as one of Robert Baratheon’s bastard sons in the first season. While he was set to join theNight’s Watch, he was captured by the Brotherhood Without Banners, but they turned him over toMelisandre(Carice Van Houten) in Season 3. After Melisandre leeches his blood, Davos Seaworth (Liam Cunningham) helps him escape and he was last seen in a boat, rowing away from Dragonstone in the Season 3 finale.

Game of Throneshas been set for a Season 7 premiere inSummer 2017, although an exact premiere date has not been given. This season will only span seven episodes long, with the eighth and final season rumored to span just six episode, airing sometime in the year 2018.
