Peyton List On Bringing Lisa Snart To ‘The Flash’

Grant Gustin and Peyton List on ‘The Flash’ (The CW)

Captain Cold and Heat Wave are back, but they have a new villainous helper in their fight against The Flash – Miss Lisa Snart.

“Tomorrow People” alum Peyton List, who plays Lisa (in the comics Golden Glider) was teamed up with Wentworth Miller, who plays her brother, Leonard Snart/Capt. Cold, and Dominic Purcell, who plays Mick Rory/Heat Wave for this Tuesday’s episode. The actress admitted it was a little intimidating to work with the two of them at first, as the “Prison Break” alums have known each other for so long and have a close bond as actors, but she quickly found out she fit right in.

“I tried to just jump right in,” Peyton told Access Hollywood. “In the beginning of the first day, it was a bit scary but by the end of it I kind of felt like I found my place amongst them, so I found where this character fit in.”

Golden Glider in the DC universe does hit the ice, but in “The Flash” TV universe – so far – Peyton hasn’t had to strap on the skates.

“They said, ‘You’re gonna be playing Golden Glider.’ I said, ‘OK!’ So I wait for the script. There wasn’t any ice skating in the script, so I was going, big sigh of relief and then, I was going, ‘I’m not gonna worry about that right now. I think I should just worry about what’s in the script, what they’re alluding to in terms of back story, what they’re not and how this character fits into this world,’ because with these comic book things, they are [kind of like] of accordions — you can just open them and more story is filled in and goes backwards, but when you’re not a writer, you don’t know what story they’re going to tell, so you kind of just have to go with what you have and leave the door open, so that’s sort of how I approached [it], because you just don’t know, maybe they will do ice skating down the line, I don’t know,” she told Access. “The ice skating costume in the comic books looks amazing, but in this world, it’d be a little cold to wear that costume on a daily basis.”

As previews of Tuesday’s episode have shown, Leonard Snart/Captain Cold wants to find out The Flash’s real identity and Peyton’s character, Lisa, is part of that storyline.

“I am trying to help my brother. I think that I’m smart enough that I know that he has a grander plan for everything and I have a job in that plan, so I need to do the job that he delegated to me, and especially if I want to prove that I can be a baddie like my brother, I’m gonna try and do my job well,” she explained. “The sort of weapon Lisa is, in the trio of Cold and Heat Wave, is that you may not see her coming and they realize [they should try a different tactic than their usual one]. Maybe try and lure someone out and because we haven’t seen Lisa yet, she’s the perfect person for that. … Try to get them to come to them instead of trying to force it out of them, so that’s really how we meet her, is sort of in disguise.”

Lisa Snart will be putting on a blond wig and setting her sights on Cisco Ramon, the S.T.A.R. Labs employee with a big heart (which we assume is still beating because The Flash ran back in time at the end of last week’s episode).

“Lisa only cares about that so much,” Peyton said of sweet Cisco and his big heart. “She has a couple of scenes where she’s flirting with him and I think she’s genuinely enjoying herself. I think she likes getting this kind of attention from men and he is a sweet guy and he falls for it immediately, so I think she — I think she genuinely likes him, but she is up to her own thing. She’s really looking after No. 1 and if she has to drop him, she will.”

When Access spoke with Dominic earlier this year, as he was still filming scenes with Wentworth and Peyton, he revealed there is an added twist of the romantic nature for his character as well.

“The interesting thing about Peyton’s character, it’s been suggested — and in a subliminal way — that Heat Wave has a thing for [Lisa] and she’s about the only person in the world that can tell him to settle down,” Dominic told Access. (Wentworth added, from Leonard’s perspective, “I’m not approving of the first part, but I see the advantage of the second.”)

Asked about this potential flirtation between Lisa and Mick/Heat Wave, Peyton said it was Dominic who was first to notice the chemistry between the characters.

“There is a sort of underlying flirtation between the two of them, and we don’t actually know what it is, but we sort of found it while we were doing the episode and we were like, ‘This is really cool and this is interesting,'” she said. “He is a very complicated guy, but he tends to go sort of tunnel vision when he wants to beat someone up or he wants to destroy something or he wants to set it on fire. She, for some reason, seems to be the character that can pull him out of that, can sort of take off the blinders and get him back in line and get him thinking straight again and that was a really fun dynamic to play where, if he’s losing his cool, she’s the one [who]… will say one flirtatious line to him and then he’s like, ‘Oh, really? Nevermind, I’m done doing what I’m doing. I’m here.’ So, that was really fun and he’s so talented and he was sort of the first one who like stumbled on it and it was a blast to explore for sure.”

At PaleyFest earlier this month, Grant Gustin (Barry Allen/The Flash) said he’s glad to have another villain in the Rogues Gallery (the episode is titled “Rogue Time”).

“It’s adding another like colorful villain to that little mold that they’ve got going and it’s a good core group of villains now, the three of them, and I think they’ll continue to come back and grow and this first one that she’s in, we don’t interact too much, but we do get to — as you see in some of the pictures, face off at least once, and yeah, it changes the dynamic, Snart having his sister there,” Grant said.

“The Flash” continues Tuesday at 8/7c on The CW.
