Fans will finally know whether or not Rickon (Art Parkinson), Osha (Natalia Tena ), and the direwolf Shaggydog made it to the Last Hearth in the upcoming season of HBO's "Game of Thrones."

The International Business Times was quick to notice an Instagram post showing a photo of Parkinson with Tena in a restaurant in Belfast, Ireland. In the other image uploaded, other casts of the hit series could be seen sitting at a table, including Alfie Allen (Theon Greyjoy), Iwan Rheon (Ramsay Bolton), and John Bradley (Samwell Tarly).

This triggered speculations that the three characters may have indeed reached the seat of House Umber. Last season, and Bran Stark (Isaac Hempstead Wright) told Osha to take the boy and his direwolf to the Last Hearth, where people remain loyal to the family. Its Lord, Greatjon Umber (Clive Mantle), fought in honor of Robb Stark (Richard Madden) back in season 1.

The website also noted that the casting calls held by the production team recently had something to do with finding another actor to play Greatjon. The producers previously let slip that they were looking for a "Lord of Noble Northern House" and "Lord of Northern Stronghold," which indeed could pertain to the leader of the House of Umber.

Meanwhile, another character may also return for the sixth season. Sandor Clegane aka The Hound (Rory McCann) may still be alive after being seriously wounded in a duel with Brienne of Tarth (Gwendoline Christie).

Viewers last saw him dying on the side of a hill, where Arya Stark (Maisie Williams) refused to put him out of his misery. Although it looked like there was no option for him but death, he was not actually shown expiring from his injuries.

Watchers on the Wall reports that the Hound could still be very much alive, as McCann was seen at a Belfast hotel during filming of the HBO series. His presence in the hotel frequently used by the cast members could only mean one thing — that his character will make a comeback for the upcoming season.

"Game of Thrones" season 6 premieres on HBO spring of 2016.
