'The Flash' Season 7: Why Is Carlos Valdes Leaving As Cisco Ramon? On 6/9/21 at 12:00 PM EDT The Flash is getting ready to say goodbye to another long-standing cast member in Season 7, as Cisco Ramon (played by Carlos Valdes) leaves Central City for Star City for a job with A.R.G.U.S. Episode 12 of the season, airing now on The CW website and app, saw Team Flash say goodbye to their long-time colleague with a goodbye rendition of Lady Gaga's "Poker Face"—the same song the team played to bring Barry (Grant Gustin) out of his coma in the plot seven years ago.
