forces the viewer to wonder what is real and what is not, like Cobb and Mal do as well. It's not intended to have a definitive take on what is real or what is not. Whether it's mix-matched dialogue, or his wedding band, or shot design, similar kid's clothes, etc. -- the movie is a play at dream versus reality, and that reality is a relative concept. The final moments are about leaving you with emotion, the one reliable constant in both dream and reality -- because film like dreams and like real life can conjure equally powerful emotions.
