Bran is beneath the mountain learning to be a greenseer. They stay for months and Meera says Bran will never leave. Jojen is withdrawn and no one seems to understand why.
Jojen, Meera and Hodor go exploring. It is too hard to take Bran in his basket so he slips inside Hodor, who goes to his safe place while it happens. Bran feels that no one should ever know that he does this. Bran learns to take the skin of a raven and flies over the ice and snow. Summer hunts with his pack.
Eventually, Bran goes into the weirwood trees. He sees through the eyes of the weirwood heart tree in Winterfell’s godswood. He sees his father and memories of Starks going back through the ages.
That chapter was sad and kind of creepy. Jojen is homesick. Why can’t he and the others go home? Is it too far and too cold, will they not make it? And what will Bran be able to do as the greenseer under the mountain? I’d so hoped Bran’s story would give him the chance to do something heroic; it doesn’t look like that will happen now.
It’s a nice, if disturbing, touch with Bran being unable to stop himself using Hodor, even though he knows it’s abusive and is ashamed of his behaviour.
