In December, Valdes revealed he would reprise his role as Cisco Ramon in an early episode of "Legends of Tomorrow," saying, "I did get to do an interesting take on this character on 'Legends of Tomorrow.'"

According to the episode's official description,

THE TEAM ORCHESTRATES A PRISON BREAK - After some of the Legends are captured and thrown into a Russian gulag during the height of the Cold War of 1986, Snart (Wentworth Miller) leads the team in an elaborate escape plan to free their comrades. However, Rip (Arthur Darvill) gives Sara (Caity Lotz) a secret side mission that could prove not only to be a liability, but fatal to the team. Dermott Downs directed the episode written by Beth Schwartz & Grainne Godfree (#105).

Airing Thursday nights at 8 pm EST on The CW, "Legends of Tomorrow" stars Caity Lotz as White Canary, Brandon Routh as the Atom, Wentworth Miller as Leonard Snart/Captain Cold, Dominic Purcell as Mick Rory/Heat Wave, Victor Garber as Professor Martin Stein (one-half of Firestorm), Franz Drameh as Jefferson "Jax" Jackson (the other half of Firestorm), Ciara Renee as Hawkgirl and Arthur Darvill as time-traveler Rip Hunter.
