Put it at the end of a reveal, after the setup has played out, then follow it with a Bruh reaction for a second beat, or an Emotional Damage sting if the moment turns on the speaker. Keep it as the punchline, not the opener, and let the next clip carry the scene.
À propos de ce son
This is a very short French voice clip, about a second and a half long, in which Morsay delivers the line 'Étonnant non?' in a flat, knowing tone. It lands as dry, mock surprise, the kind of amused disbelief you use when something was entirely predictable. The line comes from Morsay and works as a quick sarcastic reaction.
