'The Flash's 100th Episode Is Tonight & Director Tom Cavanagh Is Talking All About Barry & Nora's Father/Daughter Scene

The Flash is airing it’s 100th episode TONIGHT and star and director Tom Cavanagh is talking all about it.

“One of the things that we wanted to do with the 100th is that we felt like it’s a benchmark we should honor, but at the same time we didn’t just want to go back through our catalog and say, ‘Hey, look at the cool things that we’ve done over the years,’” he shared in a new interview with EW.

Tom added, “I think the challenge for the hundred was trying to figure out a way to hit some of those touch-tones in an organic way and still make the plot immediate and inherent to what we’re doing this season.”

He also opened up about a special moment between Barry (Grant Gustin) and Nora (Jessica Parker Kennedy) that we’ll see.

“We took a shot at having this seminal father-daughter moment. It’s one of the highlights, to me, of the show,” he says. “I’m not going to give away what it is, but the world is falling down around them and they have something beautiful transpire between them, and the two of them were heartbreaking in the best possible sense in this scene.”

Tom continued, “I’m extremely, extremely proud of both of them [Grant and Jessica]. It was a real, real pleasure to watch.”

The Flash‘s 100th episode, “What’s Past is Prologue”, airs December 4th @ 9PM ET/PT on The CW.
