“The Flash” is back and in Season 5, the Star Labs crew has a new problem with the timeline thanks to Nora West Allen, the daughter of Barry Allen (Grant Gustin) and Iris West (Candice Patton). Jessica Parker Kennedy tells Access what it’s been like suiting up as Nora, a speedster like her character’s dad, The Flash himself, and how she turns to Grant (whom she jokingly calls “dad”) for tips on making her on-camera running look effortless. “The Flash” returns Tues. Oct. 9 at 8/7c on The CW.
