The Flash executive producer Andrew Kreisberg was joined by Danielle Panabaker, Candice Patton, and Carlos Valdes at WonderCon today to talk about what's to come in the show, and plenty of new details were revealed about season one's final few episodes. To begin with, the arrival of characters from Arrow showing up in Central City was addressed, and Kreisberg confirmed that it will be Cisco who helps Laurel with a new version of the Canary Cry which will work in a similar way to the comic books. Black Canary isn't going to become a metahuman just yet then, but will have that famous sonic scream! Someone who might undergo some sort of transformation though is Caitlin Snow, with Panabaker teasing that we're going to see Killer Frost "sooner than you think." Wait, what?!
Hopefully she won't become a villain too soon anyway. Kreisberg went on to confirm that both the real Harrison Wells and Eobard Thawne (played by Matt Letscher) will return before the season ends: "You'll be seeing more of the original Harrison Wells, you'll be seeing more of Matt Letscher as Eobard Thawne, and more of Tom as Eobard Thawne." He also dropped some hints about season two villain plans. "I think we definitely want to meet the Mirror Master next year," he teased. "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." What do you guys think about these latest The Flash details?
