Hugo “Hurley” Reyes (Jorge Garcia) and Charlie Pace (Dominic Monaghan) want Jack to decide how to handle the lack of water. On the island Jack once more sees the man in the suit, and chases him. He catches up and discovers it’s his father. Frightened, he asks, “Dad?”, who silently turns and walks away.
