If Only You Knew

A character says something that connects to a fact or event of which he's unaware, usually to someone who is in the know. A common variation of this is You Look Like You've Seen a Ghost. Often shows up in supernatural settings with a Masquerade, but mundane versions can occur, such as the Arrogant Kung-Fu Guy telling Sweet Polly Oliver she "fights like a girl".

Sometimes subverted in that the seemingly Genre Blind character turns out to be hinting that he does know the truth. If neither the characters nor the audience know about the secret, but find out later, it's Foreshadowing.

This is sometimes expressed as "You have no idea" or something along those lines.

Contrast Literal Metaphor, in which Character A means what he says literally, but Character B takes it as a figure of speech; and the twin tropes It Will Never Catch On and This Is Going To Be Huge, where a character in a show set in the past makes often wildly inaccurate predictions about the future for comedic effect. See also Accidental Truth. Subtrope of Dramatic Irony.

    George: You can't see him. You wouldn't want to.
    Bessie: I do want to. How can you say a thing like that? Why can't I see him?
    George: It's impossible. His work for the Navy is top-secret. Just be happy with his paycheck. Don't even mention his name to anyone.
    Bessie: There's something fishy about this.
    George: You said it!

Literature
  • In Dragon Bones, someone tells Oreg, who looks like seventeen, to "respect his elders" or something to that effect.

To be fair, the one he was allegedly impolite towards is older than he looks, too ... but not quite as old as Oreg.
  • In Tithe, Kaye's grandmother says during an argument, "You think that it's enough to want things. You think that if you just want and want then you're just going to magically get them." Kaye, who's just found out she's a pixie, doesn't know whether to wince or smirk at the word "magically".
  • A Song of Ice and Fire: A prostitute tries to seduce Gendry by claiming that she is King Robert's bastard daughter and points to her sharing Robert's trademark raven black hair as evidence. Arya makes fun of her claims by pointing that Gendry himself has the same hair, so that does not mean much. What none of them knows is that Gendry is actually King Robert's bastard, and that owing to Robert's compulsive womanizing the prostitute is most likely right. Fortunately, Gendry is not in the mood.

Live-Action TV

    Tegeirian: Well I don't know, I don't know what he does... But dressed like that, I can tell he's a noble!
    Léodagan: He... He didn't tell you that...
    Tegeirian: That what?
    Léodagan: And you're telling me that you two are...
    Tegeirian: Well, it's... it's starting, in any case.
    Léodagan: Well it seems to me that if I was... what he is, I'd say it. In this kind of situation, it could put quite a few things on the fast track.

Web Original
  • Noob: La Quête légendaire: The webseries that preceded the movie establised Abraham was a Nun Too Holy priest, but the info came from his Man Child son Sparadrap, while the story is set in a country in which priests are supposed to stay celibate. Abraham makes his debut in the movie and reveals to the audience that there is more to him than Sparadrap knows while chatting with his younger but more aware son, and the secret is something that was so far hidden for a very, very good in-universe reason. During this occasion, Abraham spends time with Sparadrap and his friends, and keeps the "just a priest who happens to have children, nothing else to see" act for the sake of keeping the secret. Abraham eventually leaves and one of Sparadrap's female friends, who apparently didn't fully believe Abraham was a priest until meeting him, comments on how she's creeped out by the idea of Abraham being a priest. Sparadrap's brother happens to be present when she makes the remark and can't help letting the words "If only you knew." escape his mouth.
