Once Upon a Time is finally returning to Storybrooke — but it won't be the joyous celebration that everyone is expecting. That's because our ragtag group of heroes and villains have a stowaway on board in the form of Peter Pan (Robbie Kay), who switched bodies with Henry (Jared Gilmore) before being locked up in Pandora's Box.
"It's really cool that I'm actually able to be Pan," Gilmore tells TVGuide.com from the set of the ABC fairy tale drama. "It's very interesting for me getting to study Robbie; some of his facial expressions and how Peter is very cocky and mischievous. It's very different because I've been Henry for so long and now I'm a completely new person. I was excited because out of all the characters I've ever wanted to be on the show, it was Peter Pan."
After spending the first half of the season in the perilous Neverland, Emma (Jennifer Morrison) can't help but feel the worst is yet to come when they return to Storybrooke — something she's become accustomed to with being the Savior. "In this episode, Emma can't shake the feeling that something's still wrong and a lot of people around her think she's just used to being in crisis," Morrison says. "She's still on guard and doesn't feel like she has the luxury of letting her guard down to be thinking about Neal [Michael Raymond-James] or anyone beyond that."
A false sense of security is exactly what Pan wants as the residents of Storybrooke welcome the group back with a party at Granny's. "Because it is such a welcome return to Storybrooke, that's what allows the next set of events to kick off," Raymond-James says. "We are back and we are elated and feel the job is done and it's time to celebrate. We didn't see things that we could've seen. We may have let our guard down a little bit because we feel we've won."
It's Emma who is the first to notice something is off with Henry — which you can read more about here — but not everyone will be as keen to face these tough facts. "Regina's a little blindsided because she's just happy her son wants her," Lana Parrilla says. "She can justify it by saying, 'I saved you, so that's why you want me.' I don't think she knows that he's different or that he's acting different. She's just so elated to have him and for him to want her."
Suffice it to say, the #SaveHenry campaign is not over yet! "[When] all these terrible things start to happen in town, we realize that something's off, that we must not have captured Pan or somehow he's controlling things from the box," Morrison adds.
Once Upon a Time airs Sundays at 8/7c on ABC.
