The stars of The CW's superhero hit also revealed who they want to hang out with during the next crossover.
Barry Allen may be trapped in the Speed Force, but he’s still got a wedding to plan!
ET’s Leanne Aguilera sat down with the stars of The Flash -- Grant Gustin, Candice Patton, Danielle Panabaker, Carlos Valdes, Keiynan Lonsdale, Tom Cavanagh, Jesse L. Martin and executive producer Todd Helbing -- at Comic-Con on Saturday, where they dished on everything from Barry and Iris’ engagement to Killer Frost’s villain potential.
As for that wedding, however, Gustin and Patton admitted that plans are pretty much up in the air with Barry stuck inside the Speed Force.
“Someone joked earlier about a Speed Force destination wedding,” Patton said with a laugh, “inviting all our friends across the multiverse to just meet us in the Speed Force.”
While Gustin couldn’t dish too much on Barry’s journey in the upcoming fourth season, it seems that Iris will be stepping in to fill her fiance’s shoes as the de facto leader of Team Flash.
“She's kind of stepped up now that Barry's gone,” the actress explained. “We see her kind of at the mantle, like, helping everyone fight crime in Central City. It’s really cool to see her in that role, and we'll see a lot of that this season.”
Team Flash won’t just be missing its eponymous speedster. After her journey as Killer Frost in season three, Caitlin Snow (Panabaker) said goodbye to her S.T.A.R. Labs friends and left Central City in order to focus on herself.
“I don’t know if we know that Killer Frost is gone, I think there’s still a lot of different places that it could go,” Panabaker reflected. “Hopefully Caitlin’s strong, but we don’t know.”
One thing the actress seems to be certain of, is that her character won’t be too worried about a love interest this season. “Caitlin needs to take care of herself. She needs to get her own stuff right, she’s got some things to focus on.”
One of those things, in fact, might be antagonizing her former teammates! After Helbing confirmed that the upcoming season of The Flash would be the first without a speedster as the main villain, Panabaker offered up her icy alter ego.
“I think it should be Killer Frost, because who knows Team Flash better?” the actress suggested. “She knows how to fight those guys!”

As an added bonus, Helbing assured fans that The Flash will be striving to return to its lighthearted roots in season four.
“Last year got pretty dark,” he admitted. “We’re making a conscious effort to make it a lot lighter this year, and funnier.”
