And it seems that Snow and Will had a scene together, because Ginnifer and Michael both appeared on the Comic-Con skype call. If Ana is really Cinderella's stepsister, they could mean Ashley (whose actress was at the S4 premiere btw!) or they could mean Maleficent, who's showing up in 4B (which is when Will will take on a greater focus). And Ana was basically Cora's third daughter, so it could be Regina. There's a few guesses.
