What Does Retcon Mean?
Fandom CultureShort for 'retroactive continuity' — when new canon rewrites or overrides previously established facts. The character was an only child until season five declared otherwise.
Retcon in Practice
The term comes from comics fandom, where decades-long serial continuity made retroactive revisions a constant fact of life, and it spread into universal media vocabulary. Retcons range from quiet corrections to franchise-shaking reversals — resurrections, secret siblings, 'it was all a parallel timeline.' For fic writers retcons have a particular sting: a new canon installment can instantly convert years of careful canon-compliant work into accidental AU, which fandoms absorb with tags like 'canon divergence after season 4.' Fans also use the word jokingly as a verb for their own selective continuity: declaring a disliked plot development personally retconned is a time-honored coping mechanism.
Example usage
"I've personally retconned that entire season; in my heart, the finale never happened."
