Who were the Tomorrow People before they were a group of superhuman vigilantes? We’re about to find out!

In tonight’s all-new episode of The Tomorrow People (Episode 3, “Girl, Interrupted”), we get a closer look into Cara’s (Peyton List) harrowing backstory and see first-hand how she went from a shy, scrappy teenager to a kickass Tomorrow Person.

Wetpaint Entertainment chatted with Peyton about tonight’s episode, and she previewed what fans can expect from Cara’s past, including the family she left behind. She also dished on what’s ahead for Fall TV’s hottest new love triangle and why Cara is so intrigued by Stephen (Robbie Amell).

Wetpaint Entertainment: “Girl, Interrupted” is a spectacular episode for your character, Cara. What can you tell us?

Peyton List: It dives head first into Cara’s backstory. You learn a lot about her past and when she broke out and the family she left behind.

What can you tell us about who she was as a person before she became a Tomorrow Person? We know her as someone who is very intense and very focused.

You’ll see it right off the bat in the first five minutes of the episode. She was very different than she is now. You start to realize that the way she is now is probably out of necessity because she’s seen some not-so-great things. She does what she has to do for self-preservation. She may have been a little bit more shy back then. She definitely didn’t beat boys up or get into hand-to-hand combat on a daily basis back then.

I feel like Cara has had an epic fight scene in every episode. Is that a trend for the season?

Well, we definitely have plenty of fight scenes, which I think is great. We’re keeping some variety in it. We’re not doing the same kind of fighting in every episode. There’s a lot of variety. There’s a massive fight scene in Episode 3, which I really hope people enjoy because it took a lot of preparation. It was pretty spectacular.

Tell us about the training involved for scenes like that.

We did a lot of training when we were in prep, after we had done the pilot and the show was picked up. We had come up to Vancouver, and we had a little bit of time before filming. They put us in fight training because they knew with the TV schedule, you’re not going to get a lot of time to prep. So they tried to give us a solid foundation of moves. It gets easier over time, like anything. At first, you’re going, “I’m never going to learn how to do this. I’m never going to figure this out.” But over time, you do learn it faster.

Do you feel stronger? Are you rocking some serious Madonna arms now?

Oh gosh, I hope so! I’ve never thrown so many punches in my life. Who knows if I’ll ever need it down the line, but at least I have those skills!

At least you have your shirtless co-stars to look at… you’re in the middle of an Amell-Mitchell sandwich!

Oh, absolutely! I think I really am. I have the best job. Would we call it a job?

Let’s talk about the dynamic between Cara, Stephen, and John because it’s definitely heading toward love triangle territory.

It is. There is some sort of connection, som feeling, between Cara and Stephen, but the world they live in is so dangerous — there’s always something going wrong, and there’s always someone’s life in peril — that you just push those feelings to the side. You really have to deal with the task at hand. So there may be some complications there and some passive aggressive comments about, “Hey, stay away from my girlfriend!” but we are trying to work together. We’re trying to make the best of the situation and take advantage of the fact that Stephen is working for Ultra. He’s the spy on the inside! So they have to work through it. But this is only the beginning, so those feelings might grow, and if the tension gets too high, they might have to act on those feelings.

What is it that she sees in Stephen that is different that what she sees in John?

Stephen’s character and John’s character are fundamentally different. Stephen has been through so much, yet he has such a positive outlook on life. He wants the best for everybody. And John, I think, has been burned in the past, and he’s more of a realist. He’s seen a lot, and it’s tempered his expectations. He’s still trying to do the right thing because he’s essentially a very good person, but their approach to things is very different. For Cara, it’s refreshing to see someone who’s so hopeful. He’s looking at all this with fresh eyes, and that fascinates her. The Tomorrow People have been existing in this world where everything is so tense all the time, so when she meets this guy who is bit happier, it’s new for her. She’s very intrigued.

It sounds like a lot of this comes into play in “Girl, Interrupted.” Cara gets herself into a little situation at Ultra. Tell us about that. She’s a smart girl, so how did she fall into this trap?

Just a small brush with danger! [Laughs] I think that she has a lot of experience with Ultra, but given what’s going on with her, when we’re in Episode 3 and she’s being haunted by her past, it takes away her defenses that she normally has up. Her mind is elsewhere and maybe she’s not 100 percent prepared for the things that are being thrown at her. I think Cara is stubborn and headstrong, and she wants to believe that she’s in control all the time. That causes her some problems in Episode 3. She’s in a bit of hot water… It might not end so well.

Well, they kind of want to kill her…

Yeah, no big deal, right?

Assuming that she makes it out alive, where is Cara’s storyline headed this season?

From what we see in Episode 3, you get to know her a little bit better and you start to understand what she stands for. You sort of have an idea from the pilot and Episode 2, but this is the episode in which you understand what her priorities are. Regardless of what’s thrown at her, that never really changes. Her main goal is to protect the people she cares about. She’s like a mother lioness. She doesn’t want anyone to go anywhere near her friends. She’s very black and white in her views, in terms of what is right and what is wrong. That gets tested, and she has to learn to be more open to the unknown, that grey area, but she’s still pretty unapologetic.

Do you love playing this kickass female character? Because those are few and far between on TV.

Actually, it’s fun to be so deliberate and not to be questioning everything you’re doing because I think in real life, we question ourselves all the time. So to play a character that’s like, “Nope. This is what’s going to happen,” is really nice. Of course, these characters are young and they're still finding their way, so their views will change based on things that happen because they’re still figuring it all out. I think that’s a great thing that we’re going to explore.

So the Tomorrow People have the three T’s — the powers of telepathy, telekinesis, and teleportation. Which power would you like to have, personally?

I’d go with the teleportation. I wouldn’t want to be inside people’s heads. I wouldn’t want to know! We’ve explored that on the show, and I think that sounds awful. The telekinesis would be great, but I think the teleportation is so convenient. It would make life that much easier.

One of the things we love about the show is that Dan Stevens is the voice of TIM. Was that great for you to realize he was part of the cast?

What’s really great about it is that we don’t have his voiceover when we’re shooting the scene, so we’re reading it with the script supervisor when we’re on set. We don’t see how it all comes together until it airs. That’s really fun. You have an idea of how it will all come together, but you don’t really know until you see it. It’s like a little surprise everytime I hear his voice.

What do you think, Tomorrow People fans? Are you excited to dive into Cara’s backstory? Do you think Cara should stay with John or take a chance on Stephen? Tell us what you think about the new CW show in the comments!
