You know, I never even thought of that... Mostly I just thought that that whole 'reality' where they plan the heist is a dream, and that Mal was right all along (sort of negated by Cobb admiting to doing Inception on her, but still) and she's awake now after her suicide. There was a theory saying Ariadne was actually doing an inception on HIM, to have him let go of Mal. It was quite interesting.
