How Queen will factor into the storyline remains a mystery, especially after his death in the 'Crisis on Infinite Earths' crossover event a few years ago.

However, showrunner Eric Wallace shared a statement upon announcing the return, saying: "As soon as our final season was announced, we knew we wanted Stephen to come back and reprise his iconic role as Oliver Queen.

"After all, it was Oliver who originally launched Barry Allen on his heroic path. That’s why everyone on Team Flash felt so strongly that it was important to create a full-circle moment with Oliver’s return in the final season of The Flash.
