Re: Question!
HMMMM. You know, it actually hasn't really come up for Snow? At least, in the context of Elsa and Anna, she doesn't recognize that they're an adaptation of the Snow Queen (because lbr the movie is only vaguely connected) and Snow doesn't personally know them in Once land. She knows of "Joan" aka Anna because she and Charming met before Charming met Snow. Once is. kinda weird with this Frozen plot because it's incredibly, incredibly iffy on whether Arendelle in the movie is actually just the SAME Arendelle in Once-land (as opposed to every other fairytale that's just an adaptation from the Disney movie they correspond to - and/or the fairytales they correspond to themselves). It's kind of really crappy writing on the show's part that leaves it incredibly vague and it is literally never explained... nor do the characters in Storybrooke seem to acknowledge that Frozen is a movie and a thing and they are interacting with movie characters????????????
So that's a tl;dr way of saying that she hasn't actually interacted with a fairytale character yet directly from canon versus from Once-verse. The closest would be Ana's Lancelot? Camelot exists in her universe, and she actually met Sir Lancelot who is vastly different from BBC Merlin Lancelot's depiction. She and Lance have CR going based off of that... and basically Snow's approach of seeing it is that, well, yes this is Lancelot and this is the Lancelot of another world. Due to her canon, she's incredibly familiar with the concept of different worlds disconnected and connected to one another, and it's difficult for those worlds to interact. So it isn't so surprising to her that the stories/world of Camelot in her world should be different from another world's, or even the stories of Camelot differ in Storybrooke, Maine (aka our world).
So... that just boils down to: Snow isn't one to judge, in general. She's predisposed to believe the best in everyone, even those who probably shouldn't be trusted or forgiven. She isn't one to make assumptions, and considering there's people like Bucky who shares the same face as a "villain" in her canon, or Aramis and Lancelot who look the same, she's open-minded to the idea and concept that people are all different and that the things she knows and understands won't always be the same with others.
For Yuuki, what is it that she likes best about Kiseki? And what does she like the least?
