[Cobb's back on the Plane for what has to be... well, he's not sure really. He's lost track of a lot of things. It's why the top comes out and is given a spin. Perhaps he thinks it's a dream and perhaps he doesn't. He doesn't really give off the air that he's okay until the top... well, topples over.

Once it's done that he decides to take a walk. It'll help him clear his head. Help him try to prioritize a few things. So in all reality the Plane popped up on him at just the right moment.]
