Only Time Will Tell

At the end of New moon after Jacob shifts he imprints on Edward. Jacob takes up being Edwards best friend/brother/guardian believing he would want to stay together with Bella. Their relationship is strong and happy.
But unlike other imprint stories about a month later an ancient trickster sprit of the Quileute named Bayaq (The Raven) sends Jacob back into time to 1916 two years before Edward becomes a vampire.
Jacob has no idea why the trickster would do this but it has been known to also help his tribe just as much as harm it. So is this a gift or a horrible prank?
