[from trailer, Tony records message from space through his broken helmet]
Tony Stark: This thing on?... Hey Ms. Potts. If you find this recording, don't feel bad about this. Part of the journey is the end. Just for the record, being adrift in space was your promise of rescue is more fun than it sounds. Food and water ran out four days ago. Oxygen run out tomorrow morning. And that'll be it. When I drift off, I will dream about you. It's always you.
