I think Emma will find out that basically what she was worried about for the past two seasons will come to light, that she was in fact just all part of a bigger scheme and her life was a set up. I think her parents, out of fear of the potential for their daughter's evil, had found the sorcerer or the author and made a sacrifice to change the storyline for the future. I think Lily was probably meant to be the savior, or had the potential for greater good, versus Emma who was actually destined for darkness; so Snow and Charming had to go to lengths in order to swtich the stories. Emma will find out that they sacrificed not only Mal's daughter to ensure Emma would be good, but will confirm that Emma's life was a set up because instead of letting her be born to her true destiny, her destiny was fixed to be good and to be the savior.
