You are the all-powerful god of your improv world. You can create and destroy whatever your imagination can concoct, and so can your scene partner. Honor their choices as much as your own. Don’t fall back on the improv clichés of making it “all a dream” or waking up from a coma at the end of your scene. Give your world and your choices the permanence that they deserve, no matter how wacky that world and those choices have been.
