Viserys threatens Daenerys' safety when Drogo refuses to pay his debts. When Bran goes to practice his specially designed saddle that will allow him to ride after the accident, he is captured by a small group of wildlings (humans who live north of the wall, outside of "civilized" lands), however Robb and Theon are able to rescue him. Ned is left in guard of the Iron Throne while the King goes to hunt, and learns the secret left by Jon Arryn. Meanwhile, Joffrey is forced by his mother to apologize to Sansa in order to receive the crown of his father. And after Viserys crosses the line and threathens Daenerys, he is punished by Khal Drogo in a very bad way.
