Bran has been very moved by Cat's words not to climb anymore. He starting to realise the danger of heights.
Later on, it is time for the Stark household to go to King's Landing.
Bran is definitly accompanying them. He wants to become a knight and, as his older sister, is very excited to see them all in their shining armor in the capital.
But, once at KL, he soons realises the viper's nest his in, so, in a burst of anger, wargs without knowing what's he's doing, into Summer and starts attacking people.
Ned is for the moment talking with Tobbo Moht and cant intervene. Archers and knight decide to put the wolf down and Bran wargs out just in time.
It is Jaime Lannister who strikes the final blow to Summer and when Ned returns, the tensions between Starks and Lannister are at a climax.

When Ned finds out about the incest, he goes to confront Jaime instead of Cersei, still angry at him for killing the wolf, and Jaime decides that he cannot Ned live and engages duel with him. Ned loses and is killed. War with the North begins.
