Follow the Chaos

"Quick. What is the absolute worst place in this Valley one could go? The most insanely suicidal place to be found? The place where only a great fool would venture--and only an insane fool would follow?"

- How the final battle of the Codex Alera is located

Alice can't find Bob, where could he have gone?

Ka-BOOM!

Oh, there he is.

This trope centers on finding a character by the fact that they have a tendency to cause destruction wherever they go. So if you can't find them, just look for the nearest explosion. Or, if no explosions are imminent, do as the quote above and think of the place where the most potential trouble could occur and you'll end up with much the same result.

Such characters tend to be Chaotic in nature. They may be heroes who frequently use plans that are Crazy Enough to Work, or just have the plain rotten luck to always cause collateral damage wherever they go no matter what they do to avoid it. Alternatively, you may have a Mad Scientist or Bungling Inventor whose creations always blow up, letting you know if they're in their lab or not.

The intent behind this trope is that chaos they cause will give you an almost immediate idea of where to locate them. Finding a site of destruction and knowing that they've been there is separate idea which involves a more protracted hunt.

Anime and Manga

 * In the Red Riding Hood chapters of Skip Beat!, Kyouko ends up alone with a stalker in the forest, and  runs around trying to figure out where she could be. He figures it out when part of the forest explodes with her psychic energy/inner demons/hatred.

Literature

 * Tavi, the protagonist of the Codex Alera, has such a tendency for plans that are Crazy Enough to Work that the question asked in the page quote is enough for two people to simultaneously work out where he's gone less than a second after the question is asked.
 * Also, in the Discworld book Sourcery, minor character Nijel is once described as the kind of person who, if he was lost in a trackless desert, could be located by leaving out some valuable old heirloom and then hurrying back as soon as you heard it smash.
 * Matthew Reilly's Shane Schofield is a variation—he isn't tracked by the chaos, but a few allies come by the area afterwards and conclude that he's been there from all the horribly destroyed vehicles, bridges, and chunks of road.

Films

 * The Lost World: Jurassic Park. A T. Rex is rampaging through San Diego and the protagonists have to capture it. Ian Malcolm's advice? "Follow the screams."
