North:
Are you ready now, Jack? To make it official? [Jack smiles, yes. A yeti hands North the Guardian's book] Then is time you take oath. Will you, Jack Frost, vow to watch over the children of the world? To guard them with your life, their hopes, their wishes and their dreams, for they are all that we have, all that we are, and all that we will ever be?

Jack:
[turns to Jamie, who nods, then turns back to North] I will.

North:
Then congratulations, Jack Frost, for you are now, and forevermore, a Guardian.
