Good sneak peek! The interview posted also has a few interesting tidbits about this episode. As for the biggest mystery right now, the creature (which I'm guessing is what the mob is looking up at in the promo pics) is most likely a Wonderland character. If we look at flying or floating (based on the mob looking up) Wonderland characters, I really only can find 4 that I think could work: Cheshire Cat, Gryphon, Jabberwock, or Jubjub Bird.
