In its final season, 'The Flash' sees the return of Stephen Amell as Oliver Queen, the Green Arrow, says the Deadline.
According to the portal, Stephen Amell will return in a special appearance. Eric Wallace, executive director, said it was a way of repaying the 'push' that 'Arrow' gave 'The Flash' and also the fans for watching it for so many years.
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 (played by Grant Gustin) on his heroic path. That's why everyone at The 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.
