Watch Game of Thrones Season 4 Episode 7
Jaime, upset by Tyrion’s decision to ask for a trial by combat, informs him that Tyrion’s challenger would be The Mountain, or GregorClegane. Sandor and Arya get into a fight as they try to help a drying farmer, where Sandor is bitten on the neck by one of the assailants. One of the assailants is also a name of Arya’s list, Rorge, which she promptly removes from it once she sticks a sword into his heart.
In King’s Landing, Oberyn visits Tyrion, saying that he wants to be his champion since he has a score to settle with the Mountain, who had raped and murdered his sister and her entire family. The scene then shifts to Sansa at the Eyrie, where she is explained by Baelish as to why he wanted to kill Joffrey and then kisses Sansa. This is seen by her Aunt Lysa, who has already been betrothed to Lord Baelish. She later on corners Sansa and tries to push her out of the sky hole, wherein Lord Baelish comes in and convinces her not to kill Sansa, just before he pushes Lysa out of the sky hole.
