Sleeping, Tom lies in the tub of his hotel room. He's remembering the blonde he met at the bar and the things they did to each other last night. Waking suddenly, he realizes the tub is full of ice cubes. He leaps out and then wishes he hadn't. He now has a big scar across his stomach and can hardly stand. Somebody - probably the girl - has operated on him. Black market human organ stories cross his mind. What the hell did she take?
At the hospital, he learns the truth: All of his organs are still there. She put something in.
At that moment, he feels a living thing inside of him pressing to get out.
