Place this clip right after the reveal in your edit, then follow it with a sudden suspense sting if the detail gets darker, or cut straight to an oh my god wow reaction for a bigger response from another person.
Über diesen Sound
A very short spoken clip of a voice saying that's interesting in a flat, matter-of-fact tone, lasting just over a second. It lands as dryly amused and mildly intrigued rather than excited, the kind of understated reaction that makes a small detail sound funnier because the response stays so calm and brief.
