"But this time...this time is different," Dick-as-Batman explains midway through the arc. "We're not like the others. We're not gods, or aliens, we don't have special powers. Bruce was just a man, Tim. Superman brought Bruce's body to us. We buried him. And now we have to let him go."
So yeah, whichever of the multiple reasons Yost gives, he wants us to know his Tim is in a dark place.
It's my city now if I want it to be.Not Dick's. Not Bruce's. Mine.But to make it that way ...to make it right...what will I have to become?So many choices......but what will be my decision...?
Eventually he got a new version of his original Robin costume back and played a central role in Detective Comics, where he spearheaded Batman's "Gotham Knights" initiative. Eventually, Tim got his old, original, pre-New 52 origin story back, as well as the name "Robin."
