Flashback Echo

An event taking place in the present triggers a Flash Back of a very similar event that happened in the past. Resembles an Ironic Echo or Meaningful Echo except that the viewer often sees the current event first and the meaningful or ironic past event is only shown through the flashback.

Common types of Flashback Echoes include:


 * Type 1. If a character sees a large fire and starts having a Freak-Out because it triggers a traumatic flashback of when they were a kid and almost got trapped and killed in a fire. Flashbacks of forgotten or repressed traumas may be incomplete, mysterious and foreboding.
 * Type 2. As above, but with nostalgic or otherwise meaningful events.
 * Type 3. A person reminds someone of a different person they used to know, and they flashback to memories of that person, sometimes represented by visually superimposing the old person's image over the new person's.
 * Type 4. A flashback to That One Case or an event that was someone's Greatest Failure brought on by a similar event, may lead to My Greatest Second Chance.
 * Type 5. Any flashback to an event because History Repeats.

And so on.

Compare Visions of Another Self, where the "Echo" part can be conveyed through a dream, an alternate reality side trip, a holodeck or other such literary device, usually in a way that teaches the character or the audience some lesson relevant to the present.

If you're thinking of the stereotypical echoey sound effect that often acompanies flashbacks, you should be looking at Flash Back Back Back.

Could be considered having some Truth in Television, because people with PTSD (Post Traumatic Stress Disorder) have this type of flashback activated by a trigger. For instance, if a war veteran with PTSD heard gunfire, he could have a flashback to a traumatic event with the same weapon.

 * During the first half of Space Pirate Mito, Aoi keeps having fractured flashbacks (maybe that should be a trope) from 11 years ago, when his mother took him into space and they were attacked by Ranban.

 * Fullmetal Alchemist. Winry gets a type 2 in episode 22: as she hears rumors of the Elrics fighting Scar, she suddenly flashes back to her parents' retreating backs, which is then superimposed with an image of Ed and Al walking the same way.
 * Type 3 is repeatedly used in the Search for Tsunade arc of Naruto, comparing the titular character to Tsunade's old flame and younger brother, both of whom Naruto echoed by saying that becoming Hokage was his dream. For bonus points the arc showed the old flame echoing the brother and the brother bore a great physical resemblance to Naruto to amplify the comparison.

 * Both Harry and Tom respond with the same "No, sir, nothing."
 * The film takes this further and makes the exchanges word-for-word identical:

Live Action TV

 * Torchwood did this in the first episode where an odd looking knife sparks Gwen's memory and overrides the amnesia drug she was slipped earlier.

 * Dexter flash-cuts back to the moment Harry found Dexter more than once - most notably, at the end of season four.

After a couple of seconds, the vision vanishes as quickly as it came and Artyom notices a Dark One who was stalking him for a while who was likely behind all that crazy stuff.

Western Animation

 * Venture Brothers likes playing with this one. In Past Tense, there was even a fight scene that flashback echoed to a fight scene that played out in the exact same way (the winner was Brock in both fights; the other four characters involved were different).

Web Comics

 * A staple of Last Res0rt:
 * Veled has a flashback to Cypress's mother, which (apprently) convinces Veled to spare Cypress.
