Flashback - Save The World, Then Save Yourself
Vincent still felt alien in his own, now much more fragile, skin. He had the chance to be a demi-god again right in front of him, and he had sacrificed it to go back to his friends and family to aid them. The greater surprise was that he did not regret it. Granted, the risks of colds, scraped knees, getting tired within a 24 hour period, and other such inconveniences didn't exactly please him, they were nothing in the greater scheme of things.

Now it was time to hold the All-Father to his word.

He spoke with Kristoff, making it clear he would be returning, and expanding on the nature of the compact he had made with Odin before returning to help them before. Then, he went to the roof, a sheaf of papers in hand. It was a story he had written, but never gotten around to typing or sharing with anyone yet. It was a good story, one he had worked hard on, and had no certainty about his ability to recreate.

He spoke a few words, and set the manuscript aflame, letting the ashes scatter to the heavens.

"A crafted tale, unborn and never to be read, is my sacrifice, given freely, for new passage to the realm of my birth."

He had been promised passage back anyway, but there was no sense risking a breach of manners with one of the more potent gods about the universe.
