Why did his wife arrange a restaurant dinner for two?
Who was the other person? I guess you can REALLY suspend your disbelief in to thinking that it was for Malcolm and it was something she did as some sort of self manipulation because she didn't want to accept that he was gone. But even that is really far fetched to believe.
Also, I need some elaboration. What was Malcolm's unfinished business which meant he couldn't leave the earth yet? To understand Vincent Gray? What exactly was that about?
