Place it as the climax of a reveal edit, after Sudden Suspense and just before the reaction shot. Follow it with Oh My God Wow for the reaction shot, or with Nelson Ha Ha when the reveal is meant as a teasing joke rather than a serious twist.

This is Darth Vader's reveal line, spoken in a low, calm voice over just over ten seconds. It lands with sudden gravity and a wry shock, turning an ordinary confession into something huge and theatrical. The line comes from Star Wars: The Empire Strikes Back (1980), where Vader tells Luke the truth about their relationship during their duel.
