SPOILER WARNING: This article contains major spoilers for “Fury Rogue,” the latest episode of The Flash.
Wentworth Miller has bid adieu to the Arrowverse. Following a pair of episodes on DC's Legends of Tomorrow, Miller's Citizen Cold resurfaced for a one-off episode of The Flash, which marks the end of his contract with The CW. However, the episode left the door open for Cold to return down the line.
In "Fury Rogue," Barry and Cisco picked Cold up on Earth-X. He agreed to help them contain the metahuman Fallout as they transported him from one facility to another in order to escape the Thinker's plans. Cold pulled off the mission with aplomb, only to receive a lengthy goodbye in return.
As they sent him off, Cisco handed Cold a device that would enable him to travel between universes at will. They invited him to return to Earth-1 with the Ray whenever he liked, and he seemed up for the idea of some inter-dimensional travel -- indicating that Cold could return at some point down the line.
Following his addition to the spinoff series DC’s Legends of Tomorrow, Cold changed from his villainous ways into a full-blown hero. Though he sacrificed himself to save his friends in the first season, he’s managed to return several times via hallucinations and time travel. Recently, Snart returned to the show as Citizen Cold, a heroic version of the character who helped the heroes fight off evil Nazis in “Crisis on Earth-X.” Although Miller’s contract has expired, he has expressed interest in reprising his role, provided the “right story” comes along. The end of "Fury Rogue" simply reinforces the idea that Miller is willing to return.
Airing Tuesdays at 8 p.m. ET/PT on The CW, The Flash stars Grant Gustin as Barry Allen, Carlos Valdes as Cisco Ramon, Danielle Panabaker as Caitlin Snow, Candice Patton as Iris West, Jesse L. Martin as Joe West, and Tom Cavanagh as Harry Wells, with guest appearances from Keiynan Lonsdale as Wally West and Hartley Sawyer as the Elongated Man.
