[He breathes out long and hard, puffing out his cheeks with the exhale. When he speaks again a moment later, it is with more patience, because he is making a very great effort to be patient and kind and gentle. Diplomacy. He's been learning this. He can do this.]

Freyasdotter, please believe me when I say this: I bear you no ill will, and I bear your family no ill will. The Vanir are allies and companions of Odin's family, and should be treated honorably. If you have been treated poorly by the Aesir since the return of peace between our races, that was a great wrong, and for this I apologize on behalf of my people. When I return to Asgard I swear this by Mjornir: I will see that this wrong is righted.

[He can't promise the return of Vanaheim, but he can promise that the rules he, at least, is supposed to live by of will be enforced to the best of his ability for all other Asgardians.]
