Damien Darhk And Reverse-Flash Appear In New DC's Legends of Tomorrow Clip

The CW has released a second clip from tonight's sure-to-be-thrilling midseason finale of DC's Legends of Tomorrow, and it features the superhero team infiltrating a Chicago speakeasy during the Prohibition era.

Just before Nate Heywood and Ray Palmer raid the illicit establishment, Sara Lance and Dr. Martin Stein are confronted by Damien Darhk. "What are squares like you doing in a place like this?" Darhk asks. An alert Dr. Stein immediately reaches his hand out toward Jefferson "Jax" Jackson, who is sitting nearby, but before they can become Firestorm, Reverse-Flash races in and keeps them from touching each other.

"LEGION OF DOOM — When a new Time Aberration is discovered by the Legends, they find themselves headed to 1927 Chicago. The Legends quickly realize that they have been set up by Eobard Thawne (guest star Matt Letscher), Damien Darhk (guest star Neal McDonough) and the newest member of the Legion of Doom, Malcolm Merlyn (guest start John Barrowman).

While everyone is trying to help fix what they think is the mission, Jax (Franz Drameh) encourages a reluctant Stein (Victor Garber) to share his secret with the other Legends. Stein is taken captive and Sara (Caity Lotz) must make the tough choice of either stopping the Legion of Doom or saving Stein. Meanwhile, Rory (Dominic Purcell) gets an unexpected visitor and is not sure how to handle it. Brandon Routh, Nick Zano and Maisie Richardson-Sellers also star."

Ralph Hemecker directed the episode written by Sarah Nicole Jones & Ray Utarnachitt.
