"The Flash" cast is now back at work, as of today, taping the Season 4 premiere fans will see in October.

Candice Patton (Iris) told TVLine the premiere takes place six months after the events of the Season 3 finale, "and we still don't have Barry out of the Speed Force. Iris is really struggling to deal with that, and she does it in her own way."

Candice and fellow stars tweeted about their return to set to film what happens next...

... and it looks like the show's production office tweeted out a premiere title spoiler, suggesting a certain comic book storyline ahead. The entire @FLASHProdOffice account appears to have been deleted, for whatever reason, but the tweet image remained:

The original caption from @FLASHProdOffice read, "Ready for our first day of filming Season 4! We get started tomorrow, and it's gonna be epic!" Epic indeed. As TVLine noted, if "The Flash Reborn" is the premiere title, that "strongly suggests a take on Geoff Johns' six-issue 'Rebirth' arc from spring 2009, which revolved around Barry's return from an absence."

"The Flash" Season 4 premieres October 10 on The CW.
