The hit Syfy series Lost Girl returned earlier this week with the Season 4 premiere, "In Memoriam". The series centers on Bo (Anna Silk), a supernatural entity known as a succubus who feeds off the energy of humans. However, she doesn't embrace her clan's way of life, fighting to save the humans every chance she gets. Kris Holden-Ried co-stars as Dyson, a police officer and shapeshifter who can also take the form of a wolf. Zoie Palmer plays Dr. Lauren Lewis, a human doctor who has an intriguing relationship with Dyson. Both actors recently held a conference call, along with executive producer Vanessa Piazza, to discuss what else is in store for the fans in Season 4, including a look at the Monday, January 20 episode "Sleeping Beauty School".

The Season 4 premiere featured a challenging dance scene with Ksenia Solo, which Kris Holden-Ried revealed was rehearsed weeks ahead of time.

"It was fantastic, you know. It was a big endeavor for us to take on. We started rehearsing three weeks before we shot it. And even three weeks ahead, after I went to the first rehearsal, I was skeptical as to whether or not we'd be able to deliver it on time, because it wasn't a simple dance by any means. You know, a lot of times when they film a dance, they only film like shoulders up. You never see what - you know, they could just be walking around a room. We actually did it because our chorographer, (Nikeeta) was - she's a professional dancer and she really wanted us to deliver. And Ksenia (Solo) also used to dance. So sort of, you know, we really upped the stakes. And it was an amazing experience for all of us. It was such a great bonding experience between K.C. (Collins), Ksenia, and myself. And we finally got it together literally like the day before we shot and managed to just make it happen on set."

The season begins with Bo missing, and all of the characters have forgotten about her. Kris Holden-Ried talked about how challenging that was to pull off.

"It was a good challenge, you know. But that's the thing that we love Lost Girl is it's always throwing you curve balls and, you know, things that you have to adjust your performance for. Anna is such a binding force when she's on set that when we started without her, it really did feel like a different show. I remember we were all standing around and, you know, just the vibe and the personality of who sort of stepped up and takes change at certain different places. And it was really fun. I must admit. Ksenia, K.C., and I, and Paul, we all had a great time. Zoie, unfortunately, was stuck in her little world on her own."

Zoie Palmer agreed that this new aspect made it feel like a completely different show.

"It was funny because that episode felt almost like a different show for me. Because I know I'm only actually truly in it for about four and a half seconds at the end there, but that whole sort of situation, which I can't speak about at all felt like sort of we were on a different show, which is kind of fun. It's just interesting. It was like a really different vibe, you know. It was cool."

When asked if this season will reveal new information about Bo's father, Vanessa Piazza had this to say.

"I mean the story line will continue. I can't say much more than that. But yes, the story line will continue. I can't say whether or not it will resolve itself, whether you'll meet him, whether you won't, whether he exists, but it is, you know, a subject I guess of the season. But that's about all I can say."

Zoie Palmer also said that Lauren begins to come into her own this season.

"It's a really good season for Lauren. She sort of starts to have a different journey and we learn a little bit more about her history. And it's a really different, I think, side of her than we've seen. You know, we may have touched on it a little bit in other seasons, but I think she sort of starts to come into her own a little bit this year."

Since Dyson is a practically-immortal werewolf who has been living for over 1,000 years, Kris Holden-Ried said he wants to explore his character's origins, at some point.

"Right from the very beginning when I walked into the audition room, I had ideas about his back-story and exploring sort of mythology of the shape shifter. And yes, I would love to explore a bit more of that part of his world like maybe the hierarchy within the shape shifter world. You know, there was a fan who wrote some lovely fan fiction exploring it and she brought up some pretty cool ideas about, you know, the godmother werewolf or the godmother shifter. You know, just a different powers. And I think I've talked to Jay. Jay's our executive creator, co-creator of the show. And we may in season five get to explore a bit more of the mythology of the shifter world and how it will sort of relate to the world that, you know, we already have made and Bo's place in it, hopefully. As far as historical period, there's so many cool ones. I mean like he's 1000 years old, right? So what was he doing during the Renaissance? What was he doing? You know, we kind of did the dark ages and 205, you know, kind of the band of brothers riding around. But, you know, or maybe like during the 1920s when he first came to the new world with Trick, you know, that would be pretty cool."

Season 4 of Lost Girl continues Monday, January 20 at 8 PM ET on Syfy with "Sleeping Beauty School".
