This season, the writers have said, will be the last to feature flashbacks as we know them.
In season 5, Oliver will be fighting someone calling himself Promethus, and executive producer Marc Guggenheim has said that this new villain relates back to the first season, which was a simple, compelling revenge story.
To help this along,
Echo Kellum, who plays Curtis Holt, will join the cast as a regular, and we’ll see him grow into the hero Mr. Terrific.
