Happy Arya and Sansa (˶◕‿◕˶✿)
Why exactly didn't Roose Bolton recognize Arya at Harrenhal? Had he not visited Winterfell since Arya was born/was a baby? It always seemed a bit odd to me, especially given Arya's frequently remarked upon resemblance to Lyanna, who Roose certainly knew. Wouldn't "Nan"'s boldness and lack of deference seem to lend credence to any suspicions that she wasn't simply a peasant girl from the Riverlands?
