T-Rex: The whole chaos theory / timeline sensitivity to initial events thing is illustrated by butterfly idioms: it flaps its wings and later on there's a hurricane on the other side of the world, or you step on one and suddenly...
T-Rex: ...people wear hats on FEET??
T-Rex: These are the two classic examples! And it KINDA works because butterflies are so small to those as mighty as us, so it's striking that their lives could have such an impact. But there are smaller animals that have an even LARGER impact: diseases! Plagues! Pestilences!!
T-Rex: A bit of smallpox could have a HUGE effect on the world if it's in the right place at the right time!
Utahraptor: So instead of "a butterfly flaps its wings" it's "some smallpox enters the bloodstream through the lungs"?
T-Rex: YES!
Utahraptor: I dunno - I think the sayings work because butterflies are both small AND seen as inconsequential. So a big effect there is a surprise! A plague having a big effect is only surprising to people who have the unexamined, perhaps unconscious belief that their innate decency will protect them from infection.
Off panel: BUT IT'S NOT TRUE AND ALL WILL FALL IN THE FACE OF PLAGUE!!
T-Rex: Okay, yes, OBVIOUSLY all will fall in the face of plague
