The sept is close by...

While Arya was hardly as fond of her mother's gods as her sister was, even she saw the little sept her father had built for Lady Catelyn as warm and secure. And so she made a beeline to the little building, opening the door and stepping in. Glancing at the images of the Seven, Arya considered whether a prayer to the Maiden would help her, or if eighteen was too old to pray to that face of God when a loud snort behind her attracted her attention. Arya turned to see her sister standing there, with Jeyne Poole behind her.

"Well, does Arya Horseface want the gods to make her beautiful?" said Jeyne mockingly. She laughed, only for Sansa to raise her hand, causing her friend to fall silent.

Once Jeyne had stopped laughing, Sansa fixed her sister with a baleful stare. "You ruined my dress," she said.
