Digital Spy caught up with Prince Charming himself Josh Dallas to get info on season two and the character's reunion with Snow White (Ginnifer Goodwin) and their daughter Emma (Jennifer Morrison), as well as his thoughts on the shock return of magic to Storybrooke and fans' suggestions of a musical episode.
Season two of Once Upon a Time is about to launch in the UK, what can fans expect?
"It's a complete gamechanger. We have magic coming to Storybrooke, we also have everyone in the town of Storybrooke remembering who they actually are.
"A lot of people in the town are going to have a lot of questions about what's going on - what is this purple smoke and why didn't we go back to the Enchanted Forest? Should we try to get back? I think that's certainly something Charming's going to struggle with throughout this season.
"I will tell you as well that we will find out what the present-day Enchanted Forest is like now - we haven't seen it for 28 years. We'll explore that in the first half of season two."
There are so many possibilities opened up by what happened at the end of season one, so coming back did you find yourself asking, 'What could possibly happen next?'
"Absolutely. [I thought] the whole entire series was going to be about breaking the curse, so when they break it at the end of season one it was just like, "Oh...ok". It was a complete surprise to me.
"That's just a testament to [showrunners] Edward Kitsis and Adam Horowitz, what great storytellers they are. Their style of storytelling is so unique and so great to play."
How have you dealt with the success of Once Upon a Time? It's kind of become ABC's flagship show with a spinoff in development...
"It's great to be on a hit. It's definitely changed my life in many ways in terms of I have people following me sometimes with cameras and that's a little odd. It's weird to have people just calling me Prince Charming in the street. It's a lot of pressure to walk around sometimes.
"It's so good to be on something that gives people so much joy, that people are so involved with. The fans are the best. They turn up to the set and they're dressed like us and hanging around, so they've got a real passion for it and it just makes us want to keep telling the stories the best way we can."
So have you enjoyed interacting with the show's fanbase? You mingled with them at Comic-Con and you've live tweeted episodes too...
"Absolutely, because then it makes what we're doing real. Nine months out of the year we're [filming] in the studios or out in the woods so it feels like we're in this little Once Upon a Time bubble.
"When we were doing the pilot and the first season, it felt like we were doing this secret little thing. Then once it was released into the world and at Comic-Con we had to turn away 5,000 people or something like that because they couldn't get in... it's crazy. Reaction from the fans when you're on Twitter or you're at Comic-Con is just icing on the cake."
In season two we're going to delve into Snow's past a little bit. Do we learn more about Prince Charming as well?
"Of course, yeah. We were always going to go into all these characters' pasts and the different points in their lives and find out a little bit more about these people.
"So you know with Snow and Charming we're definitely going to explore a lot more of their past and their future in season two."
One of the things I'm looking forward to seeing is how Snow and Charming deal with realising that their friend Emma is their daughter...
"In this premiere episode of season two there's a beautiful moment where they're all back together as a family for the first time in 28 years. It's sweet, but it may or may not last long because there's a lot going down."
What do you think new characters like Captain Hook and Sleeping Beauty have added to the show in season two?
"I think it only makes our world busier. Our show is richer for It. We don't even have to stay in the world of Fairytale land, we can go into all Literature, which is super exciting.
"I even think it would be great to see characters like Tom Sawyer. We can go into all these different places, I think it's all good."
What fictional characters would you like to appear, then? Would you be okay if they brought in rival princes?
"Of course, of course! There's only one Prince Charming, baby! It'd be great to see Ariel and Prince Eric, to see Aladdin and Jasmine and it would be great to see all these different couples."
Once Upon a Time looks set for a third season, how much do you know about what's coming up for Charming? What are your hopes for the character?
"We haven't been told officially if there is a third season yet so I would say that we'd be back, but you never really know. But I hope he keeps developing more and becoming more interesting, more than he already is.
"I just hope that they keep delving into these fairytale stories and into their past and what makes him who he is and keep pushing forward in the future."
Fans have called for a musical episode - do you think that would ever happen?
"I don't know. I don't think so, not in the near future. But you never know, you never know. They sang in the animation. I did a lot of musicals when I first started my career so I can carry a tune well. I'll say that."
Once Upon a Time returns Sunday (April 7) at 9pm on Channel 5
