"Once Upon a Time" season 4 spoilers reveal that the show will focus on Rumple on Episode 15 as Robin Hood will make his return to Storybrooke.

Executive producer Adam Horowitz teased on his Twitter a title for the upcoming episode of "Once Upon a Time." The photo of the script showed the title "Best Laid Plans" and written by Kalinda Vasquez and Jane Espenson.

One user commented: "Wonder who its supposed to center around. also when someone as best laid plans don't they usually go wrong."

Showrunner Eddy Kitsis teased season 4 spoilers for "Once Upon a Time" during an interview with TVLine.

"Rumple is absolutely the Big Bad," he said. "And I would also say that the three women can more than hold their own. It's a very formidable team of evil coming our way."

Cartermatt said that Robin Hood (Sean Maguire) will make his anticipated return in the "reasonable near future."

Sean Maguire himself admitted during the Magic city Comic Con in Miami that he will appear soon in the ABC hit series.

"Given the way in which the character left, with him departing Storybrooke with his family, it seems impossible that he will be able to return and be with Regina," it said. "With that being said, 'impossible' doesn't really mean a whole lot on this show. Just think about how many other times that we have been surprised here over the years with things that were supposedly impossible."

The website said there's too many stories to squeeze out from the Robin Hood character like the love triangle with Regina and Maid Marian, as well as his association with the Knave of Hearts Will Scarlett.
