Original The Flash cast member Rick Cosnett is returning for a multi-episode arc

Deadline

Cosnett, whose CCPD Detective Eddie Thawne was killed off in the Season 1 finale, will return for at least three episodes in an unconventional way. “Rick’s been such a fantastic part of our Flash family since S1. And we have been looking for ways to bring him back to the show ever since,” The Flash showrunner Eric Wallace said in a statement to Deadline. “Fortunately, we’ve been able to do so now in Season 8. And Rick has been fantastic in bringing an exciting new side to his portrayal of Eddie Thawne that honors the character’s past but also takes it somewhere unexpected.” Cosnett hinted about his return on Instagram last October.
