A flashback shows Michael saying goodbye to Susan and a 2-year old Walt in a park. They fly to Rome in the morning.
Daylight comes and Sawyer and Michael wake up on the pontoon. Michael is sobbing and vows to get Walt back. The current has brought them back to the island. They collapse on the beach and Jin comes running out of the bush. His hands are tied behind his back and he's saying "Others! Others!" At least 5 people follow him, armed with clubs.
