The Flash Season 3 Episode 21 live stream. (Grant Gustin) story as he executes a dangerous plan with the rest of Team Flash in order to bring down Savitar once and for all.
At least we think that’s his deal. All we really know about evil future Barry is that he’s been running around as Savitar.
The real question is how Team Flash intends to stop him. They do have Tracy Brand, an important character introduced curiously late in season 3, who knows the secret to trapping Savitar in the Speed Force if Barry and friends can just get her to invent it four years ahead of schedule. No pressure.
Aside from Gustin, the cast of the third season of “The Flash” includes Tom Cavanagh as Harrison Wells, Danielle Panabaker as Caitlin Snow, Candice Patton as Iris West, Keiynan Lonsdale as Wally West/Kid Flash, Carlos Valdes as Cisco, Jesse L. Martin as Joe West, and Tom Felton as Julian.
“The Flash” season 3 episode 21 titled “Cause and Effect” is scheduled to air on May 9 on The CW. This episode will be followed by episode 22 titled “Infantino Street” which is directed by Michael Allowitz and is scheduled to air on May 16
