When Arya squinted the right way she could see the sword too, only it wasn't a new sword, it was Ice, her father's greatsword, all ripply Valyrian steel, and the red was Lord Eddard's blood on the blade after Ser Ilyn the King's justice had cut off his head. Yoren had made her look away when it happened, yet it seemed to her that the comet looked like Ice must have, after.
When at last she slept, she dreamed of home. The kingsroad wound its way past Winterfell on its way to the Wall, and Yoren had promised he'd leave her there with no one any wiser about who she'd been. She yearned to see her mother again, and Robb and Bran and Rickon... but it was Jon Snow she thought of most. She wished somehow they could come to the Wall before Winterfell, so Jon might muss up her hair and call her "little sister." She'd tell him, "I missed you," and he'd say it too at the very same moment, the way they always used to say things together. She would have liked that. She would have liked that better than anything.
