Re: Clearing up the ending of TDKR (MUST READ)
Yeah I don't think Alfred used the pearl's tracking device. I think it's just Bruce going to that cafe that he knew Alfred would most likely visit to let him know that he's alive and happy.
I'm fine with everything that happened in the ending although I would've preferred if the last shot was one of the following: cafe scene, Gordon finding the Batsymbol, or the Batman statue. Bruce/Batman or Gordon is the last image I wanted to cap the trilogy.
