Cobb is in a room talking with his kids on the phone. He tells them he's away for work. Apparently their grandma doesn't think he'll ever come back.
His son asks about their mom (who's Mal. We get a nice slow-mo shot of her face) but Cobb tells him she isn't coming back. Um, is she dead? How was she in the dream if she wasn't hooked up with Cobb and Arthur?
