She remembered a summer’s snow in Winterfell when Arya and Bran had ambushed her as she emerged from the keep one morning. They’d each had a dozen snowballs to hand, and she’d had none. Bran had been perched on the roof of the covered bridge, out of reach, but Sansa had chased Arya through the stables and around the kitchen until both of them were breathless. She might even have caught her, but she’d slipped on some ice. Her sister came back to see if she was hurt. When she said she wasn’t, Arya hit her in the face with another snowball but Sansa grabbed her leg and pulled her down and was rubbing snow in her hair.
