I challenge you to write a twist in to your favorite show/movie series. One thing I've enjoyed about Arrow are all of the different twists and turns it takes. I challenge you to write in a twist nobody sees coming.
My twist? Oliver dies and Sarah Lance becomes the Vigilante.
Why it should happen: Your favorite TV show has a main character. That main character is bullet proof. Stephen Amell could then be used to tell the story of Sarah Lance's time on the Island so he isn't written out of the series completely. The thing this does is add intensity to every situation the hero gets in to that is life threatening. Could the hero die again?
