Are we going to see more Saviors other than Emma and Aladdin? KITSIS: Yes, we will see another Savior other than them this year. HOROWITZ: We will. Put us down for a yes.
Do they mean Gideon? He seems to think he can become a Savior if he kills Emma and rescues the realm of the Black Fairy
I think they might have meant Henry, who has the heart of the truest believer and is the author.
