Place this clip at the end of a short scene, after Okay Let's Go sets up a departure and before the video cuts to black. If the exit needs a firmer close, follow it with Nope to shut down any reply. Keep it as the final spoken line so the scene ends on the departure.

This is a short spoken line lasting about four seconds, in which a voice says it has to go. It gives a blunt, slightly awkward feeling of an exit that arrives before anyone expects it, funny because it cuts a conversation off instead of winding it down.
