Mistaken Identity — Tag Meaning
Runs on wrong assumptions about who someone is: cases of swapped names, lookalikes, wrong-person blind dates, and characters courteously failing to correct an error until it's far too embarrassing to fix. Comedy is the default register — the longer the mistake survives, the bigger the eventual implosion — though thriller variants exist where being mistaken for someone is lethal.
What to Expect From "Mistaken Identity" Fics
An error compounding into farce or danger; the correction scene arrives precisely when it will cause maximum damage.

Identity Porn
Fandom's term — not inherently explicit, despite the name — for plots that luxuriate in identity confusion: a character romancing both halves of someone's double life without knowing they're one person, or two masked figures each oblivious to the other's civilian face. The dramatic irony is the product; Superman built the template and fandom industrialized it.

Blind Date
Sends a character to dinner with a stranger arranged by meddling friends — except in fanfic the stranger is rarely a stranger: it's the rival, the ex, the coworker they've been pining for, or the wrong table entirely and a better evening with whoever was sitting at it. The setup is a meet-cute with institutional backing.

Misunderstandings
The broader cousin of miscommunication: wrong conclusions drawn from overheard fragments, witnessed half-scenes, and assumptions nobody verifies. A classic shape is the character who sees their love interest hugging a stranger and spirals for six chapters before learning it was a sibling.

Secret Identity
Splits a character between public face and hidden truth — masked heroes, undercover royalty, spies in suburbia — and builds the story on maintenance of the wall. The genre's compound interest comes from relationships conducted across it: loving someone who only knows half of you, and the mounting cost of every lie that protects them.
