The Flash: Captain Cold and Heat Wave Featured in "Rogue Time" Poster

Before they make their way to the as-yet-untitled Arrow/The Flash spinoff, Captain Cold and Heat Wave will appear on The Flash again next week, in a new episode titled "Rogue Time."

And, yes, a new poster is teasing their return...in an episode which, if the PaleyFest trailer is any indication, will lead to a masks-down confrontation between Cold and Barry Allen.

The episode will bring back Prison Break co-stars Wentworth Miller and Dominic Purcell as Leonard Snart and Mick Rory (Captain Cold and Heat Wave, respectively), adding Peyton List as Lisa Snart, the Golden Glider. The episode airs next Tuesday at 8 p.m. ET/PT on The CW.
