All of his siblings wept for him. His mother, Catelyn, was inconsolable, spending all day by his side. Summer would howl every night, mourning his companion.

Jon Snow also came to say goodbye, but left at Catelyn's request. All of the Stark children came to say goodbye, even Theon.
After everyone had said their goodbyes and left, Catelyn was left alone with her son. She began to weep, finally realizing how alone she was. However, she was brought out of her sorrow by the sound of somebody coming up the stairs.
