T-Rex: Batman turned to Robin, who was the Jason Todd one, who if you don't know Robin was the one who came after Dick Grayson but before Tim Drake, Stephanie Brown, and Damian Wayne.
T-Rex: "I remember our first meeting, Robin!" Batman growled, crimefightingly!
T-Rex: "It was when I caught you stealing tires off the Batmobile," he said, "which contrasts with how I met the original Robin, Dick Grayson, who I adopted after his parents fell to their deaths in a rigged trapeze act, orchestrated by organized crime. He and I helped investigate the murders together, and now we fight other crimes too. As you know, your predecessor works as 'Nightwing' in a nearby town named, and I am not making this up, 'Blüdhaven'."
Utahraptor: Lotta exposition here, my friend!
T-Rex: Can't be avoided! Readers gotta know the score!!
Utahraptor: Do they though? Does your story REALLY benefit by incorporating decades of continuity assembled piecemeal by hundreds of writers? Can't you just say "Batman fights crime with Robin" and take it from there?
T-Rex: A BOLD CHOICE, Utahraptor. I'll give it a try!!
T-Rex: Batman fought crime with Robin, whose real name was a secret because then I'd have to choose a Robin and I kinda like Carrie Kelly but she's got her own continuity baggage, so -
