Gegen means "against" in German. Given that Gegen's findings and views ran counter to his species' doctrine, his name is either an ironic coincidence or an interesting choice by the episode's writers. The term "gegen" is often used by German and other European cinematographers for the "back light" during film lighting.
It's a cool observation so this removal pains me, but without a citation that this was intentional this is just speculation. -- Capricorn (talk) 03:12, January 14, 2017 (UTC)
