With just a few weeks remaining before The Flash’s Season 4 finale, Team Flash will need all the help it can get to finally take down Clifford DeVoe/The Thinker (Neil Sandilands) — especially in the wake of last week’s dramatic events. And it looks like a few Arrowverse characters will be making their way to Central City to lend a helping hand.
Tomorrow night will see Wentworth Miller make his final(?) DCTV appearance when he returns as Leo Snart, aka Citizen Cold (the Earth-X version of Captain Cold introduced in Crisis on Earth-X). Speaking to TVLine, executive producer Todd Helbing revealed that the following weeks will also find Cisco’s (Carlos Valdes) girlfriend Gypsy (Jessica Camacho), Arrow’s John Diggle (David Ramsey), and even Flash baddie Amunet Black (Katee Sackhoff) helping Team Flash to take down DeVoe once and for all.
“There’s a lot of guest cast in this last run, and it all plays into the DeVoe storyline,” Helbing said. “Anytime we get an opportunity to bring any of these guys back, we do it.”
In tonight's episode, titled “Fury Rogue,” Barry (Grant Gustin) will recruit Snart when the Fastest Man Alive will need some help to transport a dangerous meta (that would be Alexander McDonald’s Neil Borman/Fallout, as seen in the promo). Viewers will also be introduced to Siren-X, the Earth-X Nazi version of Laurel Lance (Katie Cassidy).
“She’s sort of the last remaining fighter of the Nazi regime, so she’s got a big chip on her shoulder,” Helbing teased about the character. He also offered this intriguing tidbit about this other evil version of Laurel’s sonic powers compared to those of Earth-2’s Black Siren (also played by Cassidy) who’s currently playing Team Arrow. “Her powers are pretty similar, but there’s one new thing that she can do with those powers that we’ve never seen any version of her do before.”
Can anyone take a guess as to what this new thing Siren-X will be able to do with her powers will be? Chime in with your predictions below.
