The couple has made the decision to leave for Japan a few days early, renting a cabin so they can enjoy a shorter honeymoon.

She hits the girl, and swerves off the road, crashing the car into a tree. They both fall unconscious. When she awakens, Jane realizes the girl could very well still be laying in the road, and rushes out of the car to find her, Ben on her heels. They find nothing, and Ben thinks that the girl was already found and has gotten the medical help that she would need. He also thinks the injuries weren't life-threatening, as they cannot find any blood or evidence of a collision and wants to call for help.
