CW's show 'Legacies' is just a few weeks away from its debut and we've all the reasons for you to be excited about the upcoming spin-off of 'The Vampire Diaries'. 

If you're a Potter-head or love 'The Vampire Diaries' or basically any TV series or movie where the kids go to magic school and spend their semester fighting evil, then you will love 'Legacies'. It has teenagers who go to a boarding school only for supernatural kids, who end up fighting terrifying creatures. Two such teenagers from Salvatore school are Josie and Lizzie Saltzman, daughters of Alaric (Matt Davis) and his deceased wife Josie, with Caroline Forbes (Candice King) as their surrogate mother. 

We saw the twins on 'The Vampire Diaries' when they were four and then, we met them briefly in the final season of 'The Originals' and now they are back in 'Legacies' as 15-year-old teenagers. In an interview with E! News, Kaylee Bryant, who plays Josie, said that the role was a dream come true. "It means everything to me," she told E! News at the CW's Fall Launch event for their #SeeHer campaign. "I started watching when I was 15, with my mom, on Netflix, binged it, then I started watching it week by week. So it was something I always really loved and was a big fan of to begin with, so it just means that I take it a little too seriously sometimes. I feel like I'm constantly obligated to make sure that I'm doing right by the fans, because I was a fan." 

Jenny Boyd, who plays Lizzie, said joining the show was "amazing."

"It's been like coming into this family that are all close and pre-existing," Boyd told E! News. "The family is obviously very intense and exciting."

The twins are the last remaining members of the Gemini Coven, even though they are just teenagers, they are incredible witches who haven't figured everything out yet. "I think because our show is a younger generation, it's very fresh, and we sort of take on their origins," Boyd said. "It's the very beginning for these kids. They don't really have that much experience and they're just trying to learn how to sort of harness what they have, and what they're going to use it for." 

"We have the specific siphoning powers which mean we can pull power from other things," Bryant explained. "But I mean, we come from the Parker family [their biological mother's side], where they have dealt with their emotions through their powers, and they definitely deal with their emotions through their powers." 

Bryant references to a scene where Josie sets her ex-girlfriend on fire as an example. "When you're 15 years old and you have the amount of powers that I do, it's gonna come out in really insane ways, so I think that [fans will] definitely be satisfied with the level of powers these girls have." Bryant understands that she has to live up to the expectations of her fans but at the same time, has to remind herself that she's playing a teenager. 

"Watching the four-year-old version, they're so cute, and I mean even me watching it, I got an idealistic standard of what these girls would become," she said. "So I walked in feeling so nervous and wanting so badly to make sure she was everything you could possibly imagine being the perfect specimen to be, and there comes a time when I just have to take a step back and say, you know, she's 15 years old. She's flawed." 

The on-screen sisters promise the old and new fans that they will definitely find something to love in the series. "I think there's a lot of moments that fans are going to love, and new fans are going to connect to as well," Boyd says. 'Legacies' is set to premiere on October 25 on the CW.
