Invoked: The Hero is confident in being able to track down a villain, because he is so blatantly nefarious-looking that surely someone would have spotted him.
Exploited: Alice manipulates the naive goth Nick into doing questionable acts for her gain. This way, even when things go wrong, she's cleared.
Defied: A villain tones down his appearance, style, and wardrobe in order to avoid needless suspicions.
Discussed: "Well, given that his name was 'Nicolai 'the Deathlove' Lucifer Scorpius', he sported black armor with Satanic insignia, yada yada yada, I felt trusting him would be a bad call."
Conversed: "Why does this show seem to be in love with villains that make Skeletor look like a perfectly respectable patent lawyer by comparison?" "My guess? The writers were aiming for Darker and Edgier and overshot."
