Barry and Ralph Go Undercover in New Photos from The Flash “Goldfaced”

Promo photos from a new episode of The Flash have been released. The episode is called, “Goldfaced” and it will air on February 5.

In the episode, “Barry (Grant Gustin) and Ralph (Hartley Sawyer) must go undercover as criminals in an illegal black market to purchase a device that could help them stop Cicada (Chris Klein).

Once inside, Barry and Ralph find their morality tested as they slip deeper into the criminal world, eventually having to choose between committing a crime, or losing the means to defeat one of their greatest foes. Meanwhile, Iris (Candice Patton) investigates a lead on Cicada’s whereabouts and ends up in a dangerous situation.”

I wonder what the crime is? Any thoughts?
