“The Flash” will seemingly adapt another significant storyline from the comics for its upcoming Season 4.

Marking the start of filming for the new season, The Flash Office Twitter account posted a photo earlier today that seemingly revealed the title of the Season 4 premiere. Although the photo and the Twitter account have since been deleted, reported that the picture showed a board in the production room bearing the supposed title of episode 1, “The Flash Reborn.”

TVLine reported that if “The Flash Reborn” is really the title for the season premiere, then viewers will likely see the show’s take on Geoff Johns’ six-issue “The Flash: Rebirth” arc, which revolved around Barry’s return from an absence.

At the end of the Season 3 finale, Central City was hit by a speed storm caused by the instability in the Speed Force after Jay (John Wesley Shipp) was freed from it. As Team Flash tried to figure out what to do, the Speed Force — appearing as Barry’s (Grant Gustin) mom Nora (Michelle Harrison) — suddenly popped up before them and invited Barry to fill the void. No one from the team wanted Barry to go, but he realized that this was his penance for causing all of the trouble, so he joined “Nora” into the Speed Force, ending the speed storm.

Although Barry voluntarily locked himself up in the Speed Force, the team he left behind won’t let him spend the rest of his life as a prisoner. According to the San Diego Comic-Con synopsis for Season 4 of the CW series, members of Team Flash will do everything they can to get Barry out of the Speed Force after mysterious threats start to appear in Central City. “With the fastest man alive now trapped inside an extra-dimensional energy, and unknown dangers lurking in the shadows, it will be up to Team Flash to free Barry from his own personal hell,” reads a portion of the synopsis.

Meanwhile, Candice Patton (Iris West), Keiynan Lonsdale (Wally West/Kid Flash) and Danielle Panabaker (Caitlin Snow/Killer Frost) recently took to Twitter to post some photos and video from their first day on set. See their social media posts below:

“The Flash” Season 4 will premiere on Tuesday, Oct 10 at 8 p.m. EDT on The CW.
