You were lost.

You joined Jon, Robb, and Theon on a hunting trip, looking for the first herons that take flight for the spring. Their meat was thin and gamey, but it was food.

You had fallen, slipped off a mountain and tumbled down into the snow. Laying there unconscious for two days, your body somehow survived.

When Jon had found you, he was in shambles, sobbing as he carried you back to his chambers, gently warming you up and nursing you back to health.
