ABC’s “Once Upon a Time” is taking a week off, but fans won’t want to miss episode 17 when it airs on Sunday, April 12. Titled “Heart of Gold,” the upcoming episode will find the Storybrooke residents in trouble as the Author (Patrick Fischler) roams the streets.

When viewers last left off, Emma (Jennifer Morrison) finally learned a dark secret about her parents. After weeks of lying to their daughter, Mary Margaret (Ginnifer Goodwin) and David (Josh Dallas) revealed that they had accidentally banished Maleficent’s (Kristin Bauer van Straten) child to an unknown world while trying to eliminate any evil from their own baby. Emma was horrified at what her “hero” parents had done, and quickly left after learning the truth.

The news will definitely take a toll on her, but Emma will have no time to focus on it in episode 17. The synopsis for “Heart of Gold” teases that she’ll be forced to focus on finding the Author, who escaped out into the streets of Storybrooke after being released from the pages of the Fairytale Book. It’ll be up to her to find Author before a desperate Gold (Robert Carlyle) hunts him down.

Unfortunately Gold is so bent on finding the Author that he’ll resort to blackmailing Regina (Lana Parrilla). Last week Cruella de Vil (Victoria Smufit) and Maleficent knocked out the former Evil Queen after discovering that she wasn’t completely on there side. It’s not clear what Gold has on Regina that’s not already out in the open – but it could potentially have to do with her great love, Robin Hood (Sean Maguire). 

The episode 17 description continues that Robin Hood will be featured in a flashback to the Enchanted Forest. Rumpelstiltskin will request Robin Hood’s assistance in traveling to Oz to “steal a valuable magic elixir from the Wicked Witch.” Sounds like “Once Upon a Time” viewers will get to come face-to-face with Zelena (Rebecca Mader) again!

“Once Upon a Time” Season 4, episode 17 will air on ABC on Sunday, April 12 at 8 p.m. EDT. What do you think will happen? Tweet your thoughts to @AmandaTVScoop.
