Nothing quite says "I know more than everyone" than walking slowly while everyone else is fleeing in terror. Or running while everyone else looks oblivious. Obliviously doing nothing says the opposite, but, y'know, still draws the audience's attention. Either way, Show, Don't Tell is in full effect in telling the audience who they should be paying attention to.
Characters who do this might be The Stoic, Conditioned to Accept Horror or an Action Survivor who's dealt with this sort of thing before. They might simply be complicit and showing Incriminating Indifference. In more interpersonal conflicts, they're often just the Straight Man or Team Mom, who knows the best way to act. They could simply be the Idiot Hero getting themselves in yet more trouble (Tropes Are Flexible) or trying to pull off a Secret Identity Change Trick. Often how someone Got Volunteered.
Contrast Uniformity Exception, which uses visual cues to distinguish someone, Conforming OOC Moment, for when characters are going along with the crowd when they normally wouldn't, and Flashy Protagonists, Bland Extras where the protagonist stands out because their design is more interesting than less important characters. Compare Alone in a Crowd, which is more about the alienation someone feels in a group of strangers than how they're dealing with a situation affecting everyone, Strolling Through the Chaos, which is specifically a calm person in any chaotic situation (whether or not there's anyone around to compare them to), and Conspicuously Light Patch where someone or something stands out from the background due to how traditional animation works.

- Invoked by Mikado in Durarara!!. He attempts to force Namie into turning herself in for trafficking people to be used as test subjects and her hand in Mika Harima's murder.
