The Season 4 premiere of “Once Upon a Time” is quickly approaching. The hit ABC fairytale drama returns on Sunday, and we’ve got some scoop you need to know before the magic begins – like how the canceled spinoff series, “Once Upon a Time in Wonderland,” ties into the coming season.

The success of “Once Upon a Time” led ABC to pick up “Once Upon a Time in Wonderland.” But the new show couldn’t capture the fan base of the original. Despite a different set of fairytale characters and a new story, the show failed to launch – but that doesn’t mean that those characters are disappearing. Will Scarlet aka the Knave (Michael Socha) will be making his way from “Wonderland” to Storybrooke.

As we previously reported, the Season 4 synopsis teased that Will Scarlet, a former thief and member of Robin Hood's (Sean Maguire) Merry Men, will find himself “intertwined in the goings-on in town for the first time as his mysterious past pushes him to an unknown future.” Now, creators Edward Kitsis and Adam Horowitz revealed a little bit more about the character's move in an interview with TV Line. According to the co-creators, the Knave’s role with Robin Hood and the Merry Men will “come into play very early.”

Last time viewers saw Will in the series finale of “Once Upon a Time in Wonderland,” Jafar (Naveen Andrews) had resurrected Anastasia (Emma Rigby), Will’s one true love. The twist? A love spell made Anastasia fall in love with Jafar. True love’s kiss always overpowers, though, and Will was able to break the spell and free Anastasia. But there was one more twist – Anastasia died again after Nyx (Leah Gibson) turned Jafar into a genie.

While it initially didn’t look like Will was going to get his happy ending, a little of the Well of Wonders water was able to revive Anastasia once more. The series concluded with the wedding of Alice (Sophie Lowe) and Cyrus (Peter Gadiot) in London with all her friends from Wonderland. While Alice and Cyrus lived a happy life in London, Will and Anastasia returned to Wonderland for their fairytale ending … but that doesn’t reveal how he’ll end up in Storybrooke.

Fortunately, Kitsis is promising answers in Season 4 of “Once Upon a Time.”

“We will be explaining why he’s in town and what happened" since the spinoff ended, the co-creator explained to TV Line. “I can tease that he fits rather nicely into Storybrooke. His introduction is a really fun one.”

The Knave will reportedly resurface in episode 3 of “Once Upon a Time’s” Season 4, titled “Rocky Road.” The episode will allegedly reveal more of Emma Swan’s backstory, and air on Sunday, Oct. 12.

Season 4 of “Once Upon a Time” will premiere on ABC on Sunday, Sept. 28, at 8 p.m. EDT. Are you excited to see Will Scarlet make his way to Storybrooke? Tweet your thoughts to @AmandaTVScoop.
