The Flash executive producer Aaron Helbing, who has been on the series since the first season, will not continue on to season 4.
The Helbings have been the public face of The Flash for much of seasons 2 and 3, appearing at screenings and doing Comic Con International interviews on behalf of the series. As co-showrunners, the pair have been involved with writing most of the key episodes in the last two years, including tomorrow's season finale, "Finish Line."
Fan speculation picked up after Todd Helbing was named without his brother in the official synopsis for season 4, released as part of The CW's schedule for the 2017-2018 season. ComicBook.com has confirmed that Aaron Helbing is out, although we have no further details.
Before coming to The Flash, Helbing had worked as a script coordinator on Smallville, but was best known for his work on Black Sails and Spartacus.
You can check out the official season four write-up below.
Barry Allen (Grant Gustin) lived a normal life as a perpetually tardy C.S.I. in the Central City Police Department. Barry’s life changed forever when the S.T.A.R. Labs Particle Accelerator exploded, creating a dark-matter lightning storm that struck Barry, bestowing him with super-speed and making him the fastest man alive — The Flash. But when Barry used his extraordinary abilities to travel back in time and save his mother’s life, he inadvertently created an alternate timeline known as Flashpoint; a phenomenon that gave birth to the villainous speed god known as Savitar, and changed the lives of Caitlin Snow (Danielle Panabaker) and Wally West (Keiyan Lonsdale) forever.
With the help of his adoptive father, Joe West (Jesse L. Martin), his lifelong best friend and love interest Iris West (Candice Patton), and his friends at S.T.A.R. Labs — Cisco Ramon (Carlos Valdes), C.S.I Julian Albert (Tom Felton), and an Earth-19 novelist named H.R. Wells (Tom Cavanaugh) — Barry continues to protect the people of Central City from the meta-humans that threaten it.
