Legends of Tomorrow’s Heatwave Teases Dynamic with Citizen Cold

Wentworth Miller is returning to the Arrowverse, but not as Captain Cold. When he resurfaces in the four-show crossover "Crisis on Earth-X," Miller will play Citizen Cold, Leonard Snart's doppelganger from another world -- but what does that mean for Captain Cold's longtime partner Heatwave? Speaking to CBR and other reporters, Legends of Tomorrow star Dominic Purcell teased how Heatwave will react to meeting the "new" Snart.

Asked what brings the two characters together, Purcell joked, "Oh, well, the writers brought them together." On a more serious note, he said, "What I can elaborate on is that the relationship between Heatwave and Captain Cold -- or not Captain Cold... Citizen [Cold]. It’s changed. The audience will really see a difference in his character, and also how Rory reacts to this new… you know, Captain Cold, if you will. So it was interesting. We’re dealing with some really topical stuff."

"You know, it’s always fun working with Went[worth Miller]. He’s one of my best mates, and we have an on-screen chemistry that is unsurpassed. You know, we call each other ‘frick and frack,’ ‘salt and pepper,’" Purcell added. "Again, I keep repeating this, it’s just easy working with Went, because he’s a great friend and we both work so much together and on so many shows that our rhythms are so in sync. So it’s just not difficult at all."

Miller joined the Arrowverse in 2014 for the first season of The Flash, where he debuted as Captain Cold in “Going Rogue.” Cold became a series regular for the first season of Legends of Tomorrow as a member of the crew on the Waverider alongside fellow Rogue Mick Rory, aka Heatwave, who remains a main character on the show. The Arrowverse incarnations of the characters were partners-in-crime for years, up until the death of Earth-1's Snart in Season 1.

Citizen Cold first appeared in the pages of the 2011 DC Comics event series Flashpoint, by writer Geoff Johns and artist Andy Kubert. The Flashpoint was an alternate timeline reality which came as the result of Barry Allen traveling back in time and choosing to save the life of his mother, and would eventually become the basis for the third season of The CW’s The Flash. This world was drastically different than the one Barry Allen knew, one where Aquaman’s Atlanteans and Wonder Woman’s Amazons waged war on a global scale, and one where Barry never became the Flash. In his stead, Central City had a very different hero to protect it: Citizen Cold. Though details about the Arrowverse's Citizen Cold are sparse, it seems as though he may also be a hero.
