A fairly weak start to the series with a plot so complicated I completely forgot it when I first saw it. No theft is involved; instead it's a mission to rescue Fujiko from an evil old guy who wasted lots of money on a trap built for Lupin. There are only two highlights in the episode: Jigen switching places with Lupin, and, as the title of this review suggests, Zenigata's speech about how things would be different if he weren't a descendant of Heiji Zenigata, and if his quarry weren't the grandson of Arsene Lupin.
