Where does the unique show go from here? What other well-known characters will fans soon meet? Executive producer Steve Pearlman offered up a few spoilers and teasers in a recent interview with EW, excerpts from which are below...

Look for equal time to be spent in both universes most week, with the first act typically dedicated to fairy tale characters.

Cinderella, Hansel and Gretel, among others, are on the way. Pearlman says Snow, Charming and Emma may be considered the main players, but the series wants to "branch out" and tell many stories at once.

The November 6 installment will serve a a prequel to the premiere.

Prince Charming's real-world counterpart will soon be awakened from his comatose state.

Jennifer Morrison says other folks in town will shed light on Emma: "She ends up revealing parts of herself through their stories. She kind of has a slower, steadier revelation of who she is, whereas some of the other characters will have a whole episode that’s their flashback.”

As teased in the promo above for next Sunday's episode, viewers will soon learn a lot more about the Evil Queen and her ties to Snow White.
