If you read our last column you probably noticed that Dick Grayson started out as Robin in 1940, around the age of 8 and continued in the role ‘til 1984. Yet when he became Nightwing he was only in his late teens and is still now only in his mid-twenties (roughly). So why isn’t Dick Grayson an 80-year old vigilante, beating up thugs with a zimmerframe?
