The Flash Cast Teases the Series' 'Love Letter' of a 100th Episode

The Flash is sprinting towards a major milestone. Tonight, The CW series will mark its 100th episode with a time travel-filled story that will send Barry Allen and the fans down memory lane. At the red carpet for the episode, several key cast members discussed their favorite aspects of the episode with CBR and teased its impact on the series moving forward.

"It's our love letter to the fans. We really wanted to walk them down memory lane and get them to relive some of the moments that they all fell in love with early on," executive producer Todd Helbing explained. "Some of the villains, but really tell this emotional story between father and daughter and then sort of kick off the second half of the season."

Chris Klein, who plays Season 5 antagonist Cicada, also dropped an intriguing hint about the episode. "Cicada has been doing a lot of damage up to the 100th and Team Flash is really at a loss at how to catch him and, in the 100th, they figure out that they may have a darn good way to get him," he teased.

"We haven't been doing a lot of time travel as of late. We do a lot of time travel in the 100th episode, which I love," the Flash himself Grant Gustin shared. "I mean, it gets complicated when a whole season revolves around time travel, but it's probably my favorite element that we have on the show just because literally anything can happen. We can flip anything on its head, and to see Eobard Thawne again and to see ourselves seeing some of these situations with a new lens, I thought, was really cool. It reminded me of Back to the Future. So yeah, those time travel elements are probably my favorite part."

It seems Jessica Parker Kennedy, who plays Barry and Iris' daughter Nora, would have to agree. Asked to name her favorite aspect of the episode, she said, "Time travel! Yeah, time travel." Like father, like daughter!

"I think it's cool that we revisit a lot of really iconic moments in The Flash series, and also having Tom Cavanagh direct. Having one of our own direct such an important episode is a really cool thing," added Candice Patton, who plays Iris West.

"I mean, I had a lot of favorite aspects of it, but I think the fans are going to love it because we do go back to some really cool moments that, you know, 'Oh, I remember that!' which is really cool. But honestly, having Tom Cavanagh to direct was unbelievable. Like, I get goosebumps just thinking about it, so it was fantastic," Caitlin Snow actor Danielle Panabaker said.

Airing Tuesdays at 8 p.m. ET/PT on The CW, The Flash stars Grant Gustin, Candice Patton, Carlos Valdes, Danielle Panabaker, Tom Cavanaugh, Jesse L. Martin, Danielle Nicolet, Hartley Sawyer, and Jessica Parker Kennedy.
