Importance of Ivy Leaf

When Artos returns from the hills, he comes to Ambrosius’ palace. He hands him an ivy leaf to signify that he’s given the northern territory to Ambrosius. But, when Ambrosius takes the leaf, it crumbles in his hands. This represents the fact that though Ambrosius controls the north, he will not be able to hold it; that it will be Artos who will secede him and rule in a way Ambrosius could not.
