Arya is doing needlework under the eye of Septa Mordane along with Sansa, Beth Cassel, Jeyne Poole, and Princess Myrcella. She is embarrased by the poor quality of her work and runs off. Arya resents that Sansa is beautiful and more polished than she is. Nymeria greets her at the base of the stairs. Arya named the pup after Nymeria, the warrior queen of the Rhoyne who led her people across the Narrow Sea. Sansa named hers Lady.
Arya decides to go watch the boys sparring in the practice yard. She runs into Jon and Ghost, and they watch together. Bran and Tommen are fighting each other with heavily padded wooden swords under the watchful eye of Ser Rodrik Cassel, the master-at-arms, and a group of spectators, including Robb and Theon. Jon teases her as they watch. They have always got on well together, and are the only two of Eddard's children with Stark features, the other children all inherting the Tully look. Jon also points out Prince Joffrey in the crowd, notes his arms, divided between the Baratheon stag and the Lannister lion, and comments that the Lannisters are over proud to make the queen's arms equal to the royal arms.
Bran defeats Prince Tommen. Rodrik tells Lew and Donnis to help the boys out of their armor and asks Robb and Joffrey if they would like to go another round. Joffrey wants to use real weapons, but Ser Rodrik refuses. Joffrey insults Robb, and Jon states that the prince is a little shit. Sandor steps forward to insult Rodrik and Robb. Joffrey adds his own insults and leaves with Tommen in tow. Arya returns to her room, where Catelyn and Septa Mordane are waiting to punish her for running off.
