Season 1The Pointy End
Arya escapes the Red Keep after her Braavosian sword master delays the guards sent to arrest her, but Sansa is captured. Robb hears the news and prepares the Northern armies to fight the Lannisters, leaving Bran behind to rule Winterfell.
Lysa refuses to fight the Lannisters, and Catelyn leaves to join Robb's camp. Tyrion and Bronn are surrounded by Shagga and his men. Tyrion convinces them to escort him to Tywin, who will repay them. At the camp, Tywin asks Shagga to help them in their confrontation with the Starks in exchange for even greater payment.
Joffrey appoints Tywin as his Hand. Sansa begs Joffrey to show mercy upon Ned. Joffrey agrees if Ned publicly recognizes Joffrey's claim to the throne and admits to committing treason. At the Wall, some bodies affected by the White Walkers are found. One awakens as a wight, but Jon kills it.
In Essos, Drogo's soldiers begin attacking nearby settlements, enslaving locals in order to sell them and gain the money to buy the ships necessary to cross the Narrow Sea. Drogo receives a serious wound in a fight.
