It looks like Wally West (Keiynan Lonsdale) is going to have bigger responsibilities in the upcoming Season 4 of “The Flash.”

In a recent interview with NKD mag, Lonsdale revealed that there will be a lot on Wally’s plate at the start of the new season as Barry Allen (Grant Gustin) remains locked up in the Speed Force. “We see Wally with a lot of weight on his shoulders,” the Australian actor said (via Just Jared Jr.) of what fans can expect from his character at the beginning of Season 4. “Everyone has gone through an emotional rollercoaster by the end of … Season [3] and it’s not a clean, happy ending.”

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 Garrick (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 Allen (Michelle Harrison) — 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.

While Barry is still stuck in the Speed Force when the show returns this fall, Lonsdale told Newsweek last June that Wally won’t be taking over Barry’s position as The Flash anytime soon. “It’s not something that’s on my radar,” Lonsdale said when asked if Wally is trading his yellow suit for a red one next season. “I feel as though there is so much story to tell and Wally has so much growing to do. I’d like to see that journey continue. That’s what I think is important. We need to see how these characters realistically get to where they are headed for.”

Although Barry voluntarily locked himself up, Wally and the rest of Team Flash won’t let him spend the rest of his life as a prisoner in the Speed Force. According to the San Diego Comic-Con synopsis for the show’s Season 4, 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.

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