Actually, the switch back presents a plot hole that has yet to be explained. Since the initial switch was "Freaky Friday" style and they only switched minds, then on the switch back, Syd should have been still at the café and David should have rejoined his body with the " saviors".

So how much more "wondrous" did this pilot have to be to get an "A"? I don't get the rating scheme of this site at all.
