In “Game of Thrones” Season 4, episode 7, “Mockingbird,” the fallout from the trial of Tyrion Lannister will continue to be dealt with. In the above promo, Jaime and Tyrion have a fight in Tyrion’s cell, while the Mountain makes his first Season 4 appearance.

In other parts of Westeros, the drama between Arya and the Mountain continues to unfold, and Lysa holds Sansa over the Moon Door while calling her a liar. Oh, and there’s a snow castle version of Winterfell! Meanwhile, Melisandre and Selyse have a heart-to-heart and, in Meereen, Daario makes his case to be Daenerys’s assassin.
The synopsis for “Mockingbird” reads: “Tyrion enlists an unlikely ally. Daario entreats Dany to allow him to do what he does best. Jon’s warnings about the Wall’s vulnerability fall on deaf ears. Brienne follows a new lead on the road with Pod.”

“Game of Thrones” airs Sundays at 9 p.m. ET/PT on HBO.
