A character, after realizing someone just witnessed something incredible/illegal they did, trusts them not to tell anyone because no one will believe them.
Needs a Better Name, Needs Examples
"You know, if anyone saw us, all we have to say is, "No one is going to believe you."Alice, a well-liked, mild-mannered, popular girl, is doing something extremely unusual, out of character, or downright morally wrong. Naturally, she'd prefer to keep that hidden. So when an Innocent Bystander notices her, say, sneaking away from robbing a bank wearing nothing but a shower cap and an alligator purse, what does Alice say to keep said bystander from blabbing her secret? "Go ahead and tell everyone you know. No one will believe it." Alice has just created a Bystander Cassandra. This is when someone relies on taking Refuge in Audacity to create a Cassandra Truth, thereby ensuring their secret is kept safe and the bystander doesn't go blabbing. The circumstances around the creation of a Bystander Cassandra can be as lighthearted as a celebrity messing with a fan by doing odd things to as serious as some forms of Gaslighting. This may invoke You Wouldn't Believe Me If I Told You. Can be Played for Drama if instead of a stranger the Bystander Cassandra is someone who the person with the secret knows, or the secret that required the creation of a Bystander Cassandra is a crime committed to the bystander. Subtrope of Cassandra Truth. Compare and contrast to Cassandra Gambit, as a Bystander Cassandra is at most one or two people; more than that would mean the secret is out anyways. Compare Masquerade, which is about a conspiracy to hide something unusual from the public. Contrast Hidden in Plain Sight.
