Previously, Gustin has revealed that fans will see a different Barry, following his return from Speed Force, at San Diego Comic-Con in July. He said, "For Barry it hasn't really been six months. In the Speed Force time is kind nonlinear, and I think this experience in the speed force has been different for him."

"I think when he comes out, he's kind of had this awakening and understanding of things that he's never had before, and he's able to let go of a lot of things," the actor added.

The Flash season 4 returns Tuesday (10 October) at 8pm EST on The CW network.
