The showrunner of The Flash has teased that viewers may not have seen the end of Eobard Thawne. The character, played by Tom Cavanagh, has had a complicated history on the Arrowverse series. Cavanagh originally appeared on the show as Iris West's former fiancé Eddie Thawne, though he died in the season 1 finale back in 2015. The actor had the chance to reappear in the series, continuing to play his character's descendant Eobard Thawne, also known as Reverse-Flash, who had taken on the appearance of Eddie after time traveling from the future.
The most recent episode of The Flash was the season 8 finale, titled «Negative, Part Two,» which aired on June 29, 2022. In that episode, Cavanagh plays Negative Reverse-Flash, who is acting on behalf of the entirety of the Negative Forces. After a climactic battle with The Flash, the character is seemingly destroyed for good.
