Barry (Grant Gustin) will be stuck in the Speed Force for quite a long time.

In an interview with TVLine at last Wednesday’s 43rd Saturn Awards, “The Flash” star Candice Patton revealed that Barry remains locked up in the Speed Force in the Season 4 premiere, which opens six months after the events in the Season 3 finale.

“We still don’t have Barry out of the Speed Force [in Season 4, episode 1],” Patton, who plays Iris on the series, said. “Iris is really struggling to deal with that, and she does it in her own way.”

When asked if her character will do something to get Barry out of the Speed Force, the actress responded: “That’s a very interesting question that I can’t really answer!”

At the end of Season 3 finale, Central City got hit with a series of earthquakes, which were caused by 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 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. Before joining “Nora” in the Speed Force, Barry made Iris promise that she’ll keep living and loving without him. When he entered the breach, the Speed storm stopped.

In related news, TVLine revealed that a mystery visual effects-heavy character is being cast for Season 4.

Plot details about the upcoming season are being kept under wraps, but sources told TVLine earlier this month that the villain Barry and his team will face next season is none other than Clifford DeVoe, aka The Thinker.

Executive producers Todd and Aaron Helbing also revealed at PaleyFest last March that they are planning to dial down the time travel and alternate reality concepts in Season 4. “We haven’t really talked that much about Season 4 yet, but I don’t think we’re going to do as much time traveling,” Todd said.

“We like playing with the timelines and the different time periods and future and past. [But] for now, I think we’re going to focus on the present,” added Aaron.

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