Hello again, and good day.

1.) That was indeed during the New 52, though it was late into that era, in 2015, when Duke and the "We Are Robin" crew came into the picture in prominence. Of note, Duke 'was' a Robin, albeit somewhat unorthodoxically so (though as generally proud of being as any of the '4' Robins) and for a relatively brief period during that time frame about a year before Rebirth.

2.) If you find time in your busy schedule, even if just for research (though I would hope for pleasure), I do recommend the "Endgame", "We Are Robin", "Robin War", and "Superheavy" series of books that features the character, among others things and events. Good reads all around.

As always, thank you for your time!
