Harry and Draco went after Voldemort and beat the everliving shit out of him. Narcissa hugged Draco, who blushed and squirmed, kissed Harry, who enjoyed it, and Lucius scowled and sulked.
As for Voldemort? He gave up being evil in Britain and decided to go drink maitais in Hawaii instead, possibly being evil to the tourists. When he was hungover he poked at crabs and beached jellyfish with his wand, occasionally using Unforgivable curses on them, just for kicks.
Harry and Draco made mad love, and lived together happily ever after. The end.'
