I think we're closer in opinion than we're both thinking. I agree that retcon is fine, I'm just cutting against the idea that this is not worth discussing.I know you think I should agree with you, but I don't see narrative significance as something that should always be foreshadowed. Steerpike only gradually evolves into the villain of Gormenghast. Likewise with little Annakin in the prequels. And sometimes it's okay to resort to retcon, as with the entirety of Captain Marvel.
