Comic relief is the inclusion of a humorous character, scene, or witty dialogue in an otherwise serious work, often to relieve tension. As important as suspense and tight story tension are, you need to give your audience a breather every now and then. A comic relief character can provide a moment of humor to help lighten a particularly heavy scene. Some points to keep in mind: Your character doesn't have to be a clown to be a comic.
There is an archaic term "Exeunt" used to describe a situation where many characters leave the stage. "Exeunt Omnes" would be the stage direction for everyone to leave.
