WonderCon: The Flash Panel and All-Star Team Up Trailer

“The Flash” executive producer Andrew Kreisberg and cast members Danielle Panabaker (Caitlin), Candice Patton (Iris) and Carlos Valdes (Cisco) attended the WonderCon panel for The CW show on Sunday and Comic Book Resources has a great rundown of what was talked about. Here are some highlights. Spoilers ahead for past episodes and upcoming ones!

Kreisberg said that Laurel’s (Katie Cassidy) upcoming guest appearance on “The Flash” was “one of the most fun stories that we wrote, Cisco’s interactions with Laurel. Cisco is us. What would your reaction be if you got to meet the Black Canary?” Kreisberg added that Cisco helps Laurel with a new version of the Canary Cry that will be similar to how it is used in the comic books.

Panabaker said she is really excited about her character potentially becoming Killer Frost. “You’re going to see her sooner than you think,” she said.

Kreisberg was also asked what villains maybe be coming in Season Two of “The Flash.” “I think we definitely want to meet the Mirror Master next year. I’m sure Dr. Alchemy will show up at some point. And we’ve got one thing that hopefully people will lose their minds over.”

In addition, Kreisberg mentioned that he wouldn’t be surprised to see Wally West on the show one day and that the Black Flash is not off limits either. “If there’s something that existed in the Flash universe, no matter how crazy or how silly, there’s a good chance it’ll be on the show.”

He was also asked if there was anything he could revealed about the upcoming “Arrow” / “The Flash” spinoff show. Kreisberg said, “It’s going to be like the crossovers every week. It’s going to be gonzo.” The spinoff will be “insanity and off the rails” and both “Arrow” and “The Flash” will work towards the spinoff next season.

You can also check out a new preview for the next episode of “The Flash,” titled “All-Star Team Up,” in the player below. It is officially described as follows:

“Barry (Grant Gustin) is surprised when Felicity Smoak (guest star Emily Bett Rickards) arrives from Starling City along with her boyfriend, Ray Palmer (guest star Brandon Routh), who flies in as the Atom. They’ve come to visit S.T.A.R. Labs as Ray needs help with his suit. Their timing turns out to be fortuitous because it’s all hands on deck after a meta human named Brie Larvin (guest star Emily Kinney) unleashes hundreds of robotic bees to attack and kill her former co-workers, including Dr. Tina McGee (guest star Amanda Pays). A group dinner with Barry, Felicity, Ray, Iris (Candice Patton) and Eddie (Rick Cosnett) turns into a disaster.”

Directed by Kevin Tancharoen and written by Grainne Godfree & Kai Yu Wu, “All-Star Team Up” is set to air April 14. “The Flash” airs Tuesdays at 8 P.M. EST on The CW.
