A person doesn't talk. You need to get a secret from him. So, you simulate conditions under which he does talk. You may convince him he is among allies, who depend on him telling the secret. You may convince him enough time passed that the secret is irrelevant now. You may convince him the need for secret keeping is All Just A Dream (The latter case may contain a healthy dose of Lotus Eater Machine). In short, he speaks. And then it turns out this was indeed All Just A Dream. Created by you. Examples (Warning, a Spoilered Trope): Anime and Manga FanFic
