Backstory can be revealed through flashbacks, dialogue, direct narration, summary, recollection, and exposition. It may be disclosed partially or in full, chronologically or out of order, as the main narrative unfolds.
Aristotle recognized the usefulness of dramatic revelation in his Poetics. This observation is foundational to the literary use of backstory as a device for deepening the main story.
Recollection is the fiction-writing mode in which a character calls something to mind, or remembers it. It allows a writer to bring information from earlier in the story, or from before the story begins, into the present of the narrative.
A retcon, short for retroactive continuity, is an adjustment device used when a later-created backstory conflicts with a previously written main story. It is especially common in shared universes where more than one author may shape the same backstory.
Actors create their own backstories for characters, going beyond the sometimes meager information in a script. Filling in this fictional history before the main plot events helps a performer interpret the script and create fully imagined characters.
