"Game of Thrones" is currently filming its seventh season, and ahead of the new season's premiere, HBO released a few teaser scenes which aired after the latest episode of "Westworld" last Sunday.

Watchers on the Wall posted some screenshots from the network's "Coming in 2017" clip which shows a few glimpses of Jon Snow (Kit Harington) and Arya (Maisie Williams) on horseback, and there is also a scene which features Sansa (Sophie Turner) walking outdoors. Based on the teaser, it is speculated that a Stark reunion could take place in season 7. This is something that fans have been waiting to see, as the last time that the Starks were together was in season 1.

Rumors claim that Arya and Bran (Isaac Hempstead Wright) will make their way to Winterfell after Bran spent the last few years honing his warg abilities and is now the Three-Eyed Raven, while Arya trained as an assassin at the House of Black and White. Last season, Arya declared that she's had enough of being No One and was going home to Winterfell.

Spoilers for the entire season have leaked on Reddit, and it was said that Jon heads to Dragonstone to meet Daenerys (Emilia Clarke) and leaves Sansa in charge of Winterfell. While the new King of the North is away, Bran and Arya arrive in Winterfell, and Jon receives a raven telling him that his siblings are home.

In Winterfell, Littlefinger (Aidan Gillen) tries to play Arya and Sansa against each other, using the letter Sansa wrote to Robb (Richard Madden). It can be recalled that this letter was written at the behest of Cersei (Lena Headey) and Littlefinger, to swear fealty to Joffrey (Jack Gleeson). Sansa, with Bran's help, figures out that she's being tricked.

It is said that the Stark siblings will band together against those who will attempt to turn them against each other and that Sansa will sentence Littlefinger to death. Arya, who has been trained for this, carries out the sentence.

"Game of Thrones" season 7 premieres in summer 2017 on HBO.
