Place it just before the reveal in an edit, after Sudden Suspense and before the payoff arrives. When the prediction comes true, follow it with Oh My God Wow for the reaction, or save Nelson's Ha-Ha for the moment you are proved right.
このサウンドについて
This is a short Spanish voice clip of someone saying 'Tu verás', lasting about 2.7 seconds. The delivery is calm and pointed, carrying a confident warning rather than an angry shout. It gives a listener the feeling of a promise being made, as if the speaker knows something the other person does not yet. It works as a teasing threat, a quiet comeback, or a knowing reply.
