The ninth season of The Flash is almost upon us, marking the end of the Arrowverse as we know it. And now, the longest-running Arrowverse show has confirmed three more returning characters for its final season.


Entertainment Weekly reports that season 9 will feature the return of actors Rick Cosnett, Matt Letscher and Jessica Parker Kennedy.

Cosnett, Letscher and Kennedy will reprise their roles as CCPD Detective Eddie Thawne, the original Eobard Thawne/Reverse-Flash and Barry Allen, and Iris West-Allen's daughter Nora West-Allen/XS respectively.

They join the growing list of Arrowverse alums confirmed to be returning for the final season, which also include Supergirl's Nicole Maines, Arrow's Stephen Amell and David Ramsey and Batwoman's Javicia Leslie.

"We're so excited to have Rick join us once more as we put together our final batch of emotional and thrilling episodes," said showrunner Eric Wallace. "It's especially wonderful as Rick was an integral part of the show's inaugural season. So having him return to help us conclude our show's incredible nine-year run was more than a privilege. It was a no-brainer."

Wallace teased that Kennedy will be "taking her incredible portrayal of Nora West-Allen to even greater heights" in a way viewers have "never seen before".

He added: "The Flash has always been a show about the importance of family. So having the incredible Jessica Parker Kennedy back as fan-favorite speedster XS was always in the cards."

Speaking about Letscher's return, he continued: "Having the incredibly gracious and talented Matt Letscher return for our final season was something we couldn't resist. So, we created a very special story for him, one we've been excited to tell for a while, but couldn't until now. The result is a wild and bittersweet episode we hope fans — both old and new — will love."

Who is Oliver Queen / Green Arrow? The hero on which this universe was built, Oliver Queen was a spoilt billionaire who became a hardened vigilante after five years spent fighting for survival on a hellish island. Upon returning to civilisation, he made it his mission to clean up the crime-ridden city where he was raised. In the final season of Arrow, Oliver sacrificed his life to put an end to the devastating Crisis on Infinite Earths, which has left fans puzzled as to how he will return here. Whether by flashback, a parallel universe or flat-out resurrection, expect this to get people talking.

Of his return, Amell said (via Instagram): "I'm coming back for the ninth and final season of The Flash. Why? Doesn't matter. How? Doesn't matter. Greg Berlanti called me up, and he said, 'The Flash is ending. Would you like to...' and I said, 'Yes! You don't even have to finish your sentence'. Don't ask me any more f***ing questions about it. Just tune in when it airs later this year."

What else has Stephen Amell been in? Amell broke out in the cast of edgy HBO series Hung, before landing the role of Oliver Queen. Since bowing out of the Arrowverse, he has fronted sci-fi movie Code 8 and wrestling drama Heels.

David Ramsey as John Diggle / Spartan

Who is John Diggle / Spartan? John Diggle was reluctantly assigned to be Oliver Queen's personal bodyguard-stroke-babysitter when he returned to Starling City, but a profound friendship ultimately formed between the two of them. He became a crucial asset in enabling Oliver's daring ideas, later joining him on the frontlines as the helmeted vigilante known as Spartan. At the conclusion of Arrow, John discovered a Green Lantern ring, but has since declined the enormous power it contains over fears it would tear him away from his wife and children.

What else has David Ramsey been in? Ramsey has had recurring roles in US dramas Dexter and Blue Bloods, but his time has been taken up largely by various Arrowverse projects since joining the franchise in 2012.

She spent two seasons in the cape and cowl, which saw her go up against Kate's maniacal sister Alice and other fearsome foes from Gotham City. In The Flash season 9, it is rumoured that we will see both Ryan as Batwoman and an alternate universe version where she becomes the Red Death – a villainous version of Gotham's resident vigilante, powered by the Speed Force.
