Re: if batman were to have a partner in the new series, who would you want it to be?
Dick Grayson. Use Dark Victory as a template for his story.
"I never asked for this crown. Gold is cold and heavy on the head, but so long as I am the king, I have a duty … If I must sacrifice one child to the flames to save a million from the dark … Sacrifice … is never easy, Davos. Or it is no true sacrifice." - Stannis Baratheon
