But it didn't go either way. The publishers introduced a retcon to harmonize earlier stories with later stories.
Which changed the likely intent of
both earlier stories, creating a
third “alternate universe” in which the retcon made sense...to
whatever extent it actually did make sense.
A retcon is a solution that adds, or attempts to add consistency.
Not necessarily. It’s in the wording itself. It’s
retroactive [new] continuity. It’s unnecessary to create a term for simply finding out something new. The thing that makes it retcon specifically is that it
alters something. If I don’t learn my boss’s middle name until a year into the job, it isn’t retcon.
Per Leland Chee, Continuity Database administrator aka Keeper of the Holocron for Lucas Licensing, Starwars.com July 20, 2012:
Everything outside of the films collectively known as the Expanded Universe serving as an extension of the same universe as the films. If something happened in a book or a comic, it could potentially affect everything else happening in the universe. Any discrepancies that resulted would be resolved or retconned (short for retroactive continuity, i.e.
changes from previously established continuity) across the board to try and create some consistency.
Per Google:
(in a film, television series, or other fictional work) a piece of new information that imposes a
different interpretation on previously described events, typically used to facilitate a dramatic plot shift or account for an inconsistency.
Per Dictionary.com:
a subsequent
revision of an established story in film, TV, video games, or comics:
“In an awkward retcon of his origin story, the hero’s parents survived the attack but suffered complete memory loss.”
