"The Flash" executive producer Gabrielle Stanton discussed Jay Garrick's relationship to Barry, what version of Wally West they plan to use, Barry's emotional arc and more details about the show's sophomore season during an interview with Collider.
"[Barry] went through a lot, at the end of last season," she explained. "He's definitely going to start this season with a step back and be like, 'What am I doing? Why am I doing this?' If last season was the journey of Barry discovering he's a hero, this season is definitely him trying to figure out what that means. What is it to be a hero? What does he need to be a hero? What is it going to do to his personal relationships? It's an evolution that's going to start in the beginning of the season, and go all season long. You're going to see, early on, Barry coming into his own as The Flash, a little bit more. He has to make some terrible decisions, and he's going to struggle with those. He's going to think about, can I live with myself, having to make those decisions, and still do what I do? That's something he's going to be struggling with, for the first half of the season. Some of it is learning how to be okay with his past decisions, some of it is learning how to make better decisions, in the future, and some of it is about how he can let people help him make decisions."
"We're introducing Jay Garrick, who will be a mentory character to Barry. Jay has seen some things that Barry hasn't seen, and he's going to be helping him through the process," she revealed.
"I think [Barry] is a little more careful to trust everyone because of what happened, as anyone would be. But, he's still Barry. He still has that fantastic, optimistic energy. He's still willing to say, 'Okay, let me see what you're going to do, and then I'll decide,'" she continued.
She also weighed in on where some of the supporting cast members would be this season, including Joe West's new role in the Central City Police Department. "When we open up the season, The Flash and meta-humans, and the idea that there's other stuff out there, is going to be a lot more in the zeitgeist. Joe is going to be working on the meta-human task force at the police station, so when a call comes in, if it's a bank robber with wings and horns and he's shooting fire, than they'll probably send Joe."
As to Wally West, she divulged, "I knew people were going to be excited about Wally West, but I didn't know they were going to be this excited about Wally West, which is a bummer because I can tell you nothing about Wally West. I can say that he's going to be on [the show] and it's going to be really exciting. The fans will definitely like what we're doing with him."
"We want to stay respectful and totally satisfy what the fans want out of this," she added. "But on the other hand, we also need to change the character, twist things and put our own spin on it, so that it's not exactly what everyone expects. Otherwise, you're like, 'We're introducing Wally West,' and someone looks it up on Wikipedia and knows the story, so they don't watch. So, it will definitely be our twist on the Wally West character."
Regarding the Killer Frost tease last season, she said, "It's going to be a slower burn on that. That was just to keep people guessing. Who knows when Killer Frost is going to turn up? We did the helmet. We try to drop little Easter eggs. What I really like about 'The Flash' is that I am a comic book fan, so I know a lot of this stuff, but my husband is not a comic book fan at all, and he still gets everything."
Like Barry, Cisco will also embark on an emotional journey after the big Reverse Flash reveal last season. "Wells was like a father to him and it was pretty devastating, losing him, and it was pretty devastating when he tried to kill him. So, he's definitely going on a journey, this season."
