The Flash Season 6 News

The Flash season 6 is in full swing! That means way more speedster shenanigans and time-traveling adventures with Barry Allen and his team at STAR Labs. 

But have been some changes in the new season, and we’re not just talking about Barry’s sharp new Flash costume! Current showrunner Todd Helbing was replaced by Eric Wallace, and the series was rocked by the events of Crisis on Infinite Earths.

“From his first day on The Flash, Todd Helbing has been a leader on the show, beloved by the cast and crew for his exceptional talent, vision and wonderful attitude. We are all sad to see him go, but we will all be better for the many shows he will no doubt create and run in the future,” The Flash executive producer Greg Berlanti said in a statement (via The Hollywood Reporter). “Eric Wallace has proven his own exceptional talent and voice since season four, and we couldn’t be more thrilled to watch how he shapes the future of Team Flash and the many thrilling adventures that lay ahead for our characters and dedicated fans.”

Among other things, this season is putting the women of Team Flash and the Central City Citizen front and center. We wrote more about that right here.

Here’s everything you need to know to stay up to date on the adventures of Team Flash!

The Flash Season 6 Return Date

The Flash season 6 episode 16 is called “So Long and Goodnight.” It was originally scheduled to air on March 31, but has been temporarily removed from The CW schedule, and no new air date has been announced as of this writing. The earliest we expect to see it is April 7. We’re not sure if its delay has anything to do with the suspension of production that has affected all CW shows because of the ongoing coronavirus pandemic.

“After Black Hole hires Rag Doll (guest star Troy James) to kill Joe (Jesse L. Martin), Singh (guest star Patrick Sabongui) suggests he go into Witness Protection but Joe refuses to stop investigating Carver (guest star Eric Nenninger).  While investigating Carver with Cisco (Carlos Valdes), Ralph (Hartley Sawyer) runs into Sue (guest star Natalie Dreyfuss). Iris (Candice Patton) becomes suspicious of Eva (guest star Efrat Dor).”

The Flash Season 6 Episodes

We’re keeping track of everything we know about the new season right here! We’ll update this with new details as they become available. One interesting note about this new season, while it will have the traditional 22 episode season, they’re treating this like two mini-seasons. So the first batch of episodes will focus on Bloodwork, then we’ll get the Crisis on Infinite Earths interlude, and when the show returns after that, they’ll be treating it like a brand new season, with a second big bad!

The Flash Season 6 Villain

Sendhil Ramamurthy (best known for his work on Heroes) played Dr. Ramsey Rosso a.k.a. Bloodwork for the first half of the season. Rosso is a brilliant physician who works on hematological oncology. He’s a friend of S.T.A.R. Labs’ Caitlin Snow (Danielle Panabaker), and meets back up with her after an unexpected event. Rosso’s desire to defy the laws of nature take him down a dark path where he enters the pantheon of Flash villainy. 

The villain for the second half of the season is yet to be confirmed, but we have our suspicions. 

Efrat Dor (Mayans MCSneaky Pete) is joining the cast of The Flash in its post-Crisis Season 6B portion (referred to as “Graphic Novel #2”), reports EW. She will play Eva McCulloch, whose official description reads:

“A quantum engineer and co-founder of McCulloch Technologies, Eva McCulloch is a scientific genius who works on the bleeding edge. Eva has been away from Central City for many years. But a chance meeting with Iris West-Allen results in a surprising alliance that pushes the boundaries of sanity, while also uncovering a vast conspiracy to take down Team Flash and its allies.”

Intriguingly, as the report points out, the closeness of the name Eva McCulloch to that of Evan McCulloch, a.k.a. the once-mentioned villainous Mirror Master of Earth 2 (and of the comics,) is hardly coincidental, although not to be confused with the show’s Earth 1 Mirror Master, Sam Scudder, with whom Team Flash has tangled back in Season 3. Thus, amongst the numerous possibilities for Eva’s origin is the theory that she is Earth 2 Mirror Master, gender-swapped post-Crisis. Such a concept wouldn’t even be unprecedented, since the timeline alterations of “Flashpoint” saw John Diggle’s baby daughter, Sara, replaced with son John Jr., a.k.a. “JJ.”

The Flash Season 6 Story

The Flash has to deal with the aftershocks of this year’s Crisis on Infinite Earths crossover event, which promises to shake the Arrowverse to its very core. There’s no doubt that life will change for Barry, especially after an event as famous as DC’s biggest and best Crisis. As some of you already know, a DC Crisis usually means that a Flash is about to die.

You can also expect some big changes coming for Caitlin Snow and Killer Frost this year. We have more details on that right here.

We’ll keep you updated as we hear more about The Flash season 6. 

The Flash Season 6 Cast

Natalie Dreyfuss (The OriginalsStill the King) has joined The Flash Season 6 for the recurring role of Sue Dearbon. The casting foreshadows a monumental development for the television arc of Ralph Dibny/Elongated Man, since, as discerning DC Comic fans already know, Sue is destined to become his wife and cohort. The character first appeared back in The Flash Vol 1 #119, dated March 1961, introduced as a wealthy-family-hailing debutante who the enamored superheroic schmoe, Ralph, manages to woo after some crimefighting circumstances. The comic-depicted caste-clash will be prevalent on television, and Ralph will learn that there’s more to Sue’s backstory than fancy soirees.

And yes, of course Tom Cavanagh is back, and this time, he’s be playing a new version of Harrison Wells, known as “Nash” Wells this time around.
