POSSIBLE SPOLIERS
Had a second watch, and I'm now wondering about Cobb's Wedding Ring. I can't be sure, but I got the impression he wasn't always wearing it, depending upon the sequence in the film.
Another clue as to dream/awake distinctions? Another candidate for Cobb's Totem? Now I want to know whether his Wedding Ring is being worn at the end.
END SPOILERS
Try to be reasonable... its easier than you think...
