Here is an article with some information regarding Emma Swan and what’s to come for her character this season. It seem like ep. 17 Hat Trick will be a turning point for Emma to possibly start believing in fairy tales. From an interview with Jennifer Morrison (Emma), we learn:
Believing that the curse is real, and that the Storybrooke residents are actually fairy tale characters, means that Emma will have to accept that her new best friend, Mary Margaret, is actually her mother, whose actual identity is also Snow White – both of which the roommates often joke about in passing. “Ultimately, there’s going to be a point where that has to happen,” Morrison says. “I think we’re headed toward those worlds having to be exposed in some way. Emma can’t be skeptical for six years.”
