Executive producers Todd Helbing and Aaron Helbing spoke about the episode in a promo video. Todd said, "We get to see our team go out and be a 25-year-old and have fun for a change. So they all go out to a club."

Then we see Barry, Iris, Jesse and Caitlin dancing in a club, where they see another speedster stealing everyone's wallets. "There is a new meta-human that shows up, who is a speedster. And it's our first female speedster named Trajectory. She is going a lot faster, than Barry," Todd adds.

Then the promo shows Barry saying, "I wanna be fast enough to stop Zoom and any speedster that tried to hurt my friends." Aaron then teased fans by saying, "I would not miss the last five minutes."
