Place it right after the confusing line in a gameplay edit, then follow it with Enemy Spotted when the plan actually appears, or cut to Nope when the idea gets rejected. Keep it as a single reaction beat between dialogue lines, not as a recurring sting throughout the video.
À propos de ce son
This is a half-second French voice taunt from Age of Empires II, a single male voice asking 'Roggan?' in a flat, questioning tone. It lands as puzzled and deadpan, the kind of confused reply that makes a strange claim sound even stranger. It is taunt 29 from the game's French taunt set, a quick in-game chat line players send instead of typing.
