Head canon about the Jolly Roger and Hook's escape from Neverland.
The curse cloud covers Storybrooke at the end of Going Home, when it clears two men remain. One tall and dark wearing black leather, one shorter with brown hair and eyes wearing the clothes of the land without magic. They look at each other and glance down the road at the retreating yellow vessel. Everyone else is gone including the town.
