E! Online reports that Rickards will be arriving in Central City for the fourth episode of the upcoming season as Rosalind "Rosa" Dillon, better known to comic book fans as The Top -- the Rogue with the power to literally make people's heads spin. The character is canonically a man, but in The Flash version Rickards' Top will play the Bonnie to Mirror Master's Clyde. The latter role will be played by Aquariusalum Grey Damon.
"[The episode] is kind of the origin of Mirror Master...We're really excited," executive producer Aaron Helbing told E!. "It's the origin story of him, but it's this struggle between Mirror Master and Captain Cold [Wentworth Miller] and you get to see who comes out on top," added fellow EP Todd Helbing.
That's right, the episode will also include Captain Cold's first return back to The Flash since his departure from the Legends of Tomorrowteam at the end of last season.
The Flash premieres Oct. 4 at 8/7c on The CW.
