...he trailer and know from the comics, that all three could be in the movie. Robin dead as we can see the Joker got to him; Nightwing, as in the comics, was off on his own as Batman had a new Robin, and then when he thought Robin was dead it turned out he was the Red Hood. That, coupled with the clips we get to see in the trailer and the AGE this batman is (meaning enough time has passed for all of these events to take place), makes my speculation ENTIRELY possible. If these articles upset you, I am truly sorry. But the rest of the community, they seem to be enjoying it.
