The sixth season of The Flash has put Barry Allen and his allies through several trials and tribulations. First, the team had to prepare for Barry's potential death leading up to the "Crisis on Infinite Earths" crossover. Then, post-"Crisis" they have had to deal with the terrorist group known as Black Hole and the death of the Speed Force.

Speaking to CBR in an exclusive interview, Hartley Sawyer, who portrays Ralph Dibny/Elongated Man, spoke about how "Crisis" helped prepare Team Flash for an eventuality like this.

"I mean, he's there for Team Flash no matter what," Sawyer said. "Anything that Barry is unable to do, there's no doubt that -- and this is, I think, why the show has lived so long, that it's the family, it's the Flash family, and it really is a team and a family -- and so he's there to help Killer Frost, Caitlin, Cisco and everybody with anything that they may need in terms of Barry starting to lose his speed, but that's also going to impact everybody in a way."

He also explains how "Crisis" helped the team to deal with Barry losing the Speed Force. "It prepared them in a way for this and it deepened their relationship too, which I think is what's so special about this team and about the show is all the trials they face deepen the relationship amongst the core group," he said.

During the episode "Death of the Speed Force," Barry learned that allowing the Spectre to supercharge his speed during the Crisis poisoned the Speed Force, resulting in its death. In the following episode, "The Exorcism of Nash Wells," Barry, Caitlin and Cisco resolved to build their own Speed Force.
