Re: Would Richard Grayson be part of this movie?
I know we haven't seen him post-Forever Evil, but the solicit for #6 describes "Nightwing's final fate!" (Bruce Wayne similarly "died" with the same tagline) and Fabok's Batman: Eternal teaser image features most of the Bat-Family except for Dick, but a new blonde-haired man wearing a domino mask reminiscent of Dick's.
"But that's the thing about Batman. Batman thinks of everything."
"There's always a way. When the odds are impossible- do the impossible."
