New The Flash Clip: The Atom Gets His Name

Airing at 8 p.m. ET/PT on The CW, this episode will guest star Arrow‘s Emily Bett Rickards as Felicity Smoak and Brandon Routh as Ray Palmer, presumably setting the stage for his role in the as-yet-untitled spinoff series set to debut on The CW at midseason next year.

You can check it out below.

Barry (Grant Gustin) is surprised when Felicity Smoak (guest star Emily Bett Rickards) arrives from Starling City along with her boyfriend, Ray Palmer (guest star Brandon Routh), who flies in as the Atom. They’ve come to visit S.T.A.R. Labs as Ray needs help with his suit. Their timing turns out to be fortuitous because it’s all hands on deck after a meta human named Brie Larvin (guest star Emily Kinney) unleashes hundreds of robotic bees to attack and kill her former co-workers, including Dr. Tina McGee (guest star Amanda Pays). A group dinner with Barry, Felicity, Ray, Iris (Candice Patton) and Eddie (Rick Cosnett) turns into a disaster.

Kevin Tancharoen directed the episode written by Grainne Godfree & Kai Yu Wu. The “All-Star Team Up” episode of The Flash is scheduled to air on April 14, 2015.
