Sansa thought of the games she would play as a young child, always insisting that Robb joined in. He could never refuse and so he would be the brave knight to her captured princess, with Arya often playing the villain. The rescue attempt would always end with a sword fight while Sansa cheered Robb on, and when he won he would pick her up and spin her around while she laughed happily, kissing his cheek and declaring him the bravest knight in the seven kingdoms.
Though they were silly games of pretend, still Sansa waited in King’s Landing with the hope that Robb would be her knight just one more time.
Growing up at Winterfell, all I ever wanted was to escape, to come here, to the capital. To see the southern knights and their painted armor, King’s Landing after dark, all the candles burning in all those windows.
