X-Men Origins: Wolverine2009

Kayla Silverfox:
You know why the moon is so lonely? 'Cause she used to have a lover. His name was wolverine. They lived in the Spirit World together. And every night they'd wander the skies together. But one of the other spirits was jealous. The Trickster wanted the Moon for himself. So he told wolverine that the Moon asked for flowers. He told him to come to our world and pick her some wild roses. Wolverine didn't know that once you leave the Spirit World, you can never go back. {Now he's trapped here} Every night the Moon searches for him, and every night he sees her in the sky and howls her name, but he can never touch her again.
