“Ser Sweetrobin,” Lord Robert said, and Alayne knew that she dare not wait for Mya to return. She helped the boy dismount, and hand in hand they walked out onto the bare stone saddle, their cloaks snapping and flapping behind them. All around was empty air and sky, the ground falling away sharply to either side. There was ice underfoot, and broken stones just waiting to turn an ankle, and the wind was howling fiercely. It sounds like a wolf, thought Sansa. A ghost wolf, big as mountains.

And then they were on the other side, and Mya Stone was laughing and lifting Robert for a hug.
