Old Nan had told him the same story once, Bran remembered, but when he asked Robb if it was true, his brother laughed and asked him if he believed in grumkins too. He wished Robb were with them now. I’d tell him I could fly, but he wouldn’t believe, so I’d have to show him. I bet that he could learn to fly too, him and Arya and Sansa, even baby Rickon and Jon Snow. We could all be ravens and live in Maester Luwin’s rookery.
