Frodo stood at the stern of the ship, watching the land slowly vanish.
He hadn't expected to come home from that blasted Quest at all, and he'd been correct. The Shire, still populated by the same people he had known since faunthood, had changed during his absence; he had seen too much. The Shire wasn't home anymore, and it hurt too much to pretend. So, when the time came, he simply turned everything over to Sam and joined the Elves heading to the sea.
Bilbo called this another adventure, but Frodo had no illusions. He was losing everything, at last.
