I've been binge-reading Fables this past month, and I think my least favorite thing about binge-consuming media is noticing minor contradictions that I would otherwise have been blissfully unaware of. I read Fairest 1: Wide Awake today, which tells the backstory of Sleeping Beauty, and which outright contradicts these two (admittedly throwaway) panels from Cinderella: From Fabletown with Love:
Those aren't the same fairies, and Frau Totenkinder wasn't involved at all (and it's been implied that she was behind Briar Rose's curse in Fables proper, too, which just makes me even more annoyed).
Actually, Fairest 1 plays fast and loose with the Fables canon in general.
