Following the trailer released last week for The Flash's fourth episode, "Going Rogue", The CW has released a new clip which shows that Barry Allen (Grant Gustin) is close to coming up with his own superhero name. While he initially refers to himself as "The Streak" in the third person, something which does not sit well with Joe West (Jesse L. Martin), Barry almost utters The Flash before being interrupted by Iris (Candice Patton).

While we don't see him in this clip, fans do get some background on Leonard Snart, a.k.a. Captain Cold, played by guest star Wentworth Miller, whose father was a dirty cop and is still behind bars. Leonard seems intent on following in his father's footsteps, and tries to commit a robbery before Barry stops him and his group.

This episode will also feature an appearance from Felicity Smoak (Arrow's Emily Bett Rickards), who heard about Barry's new abilities and came to check them out for herself. She joins him at S.T.A.R. Labs to help stop Snart after it's revealed that Snart his gotten his hands on a stolen "cold gun," which could kill The Flash. Dr. Wells (Tom Cavanagh) is furious when he finds out that Cisco (Carlos Valdes) built the cold gun without telling anyone and now it's missing. Meanwhile, Iris is getting the silent treatment from Joe because of her relationship with Eddie (Rick Cosnett). Finally, The Flash and Captain Cold have an epic confrontation.
