<Snipped quote by Byrd Man>
You know, I won't pretend to have invented the trope, but the earliest instance I can recall is me playing Detective John Grayson as a lead-in to a Robin run that never happened. Which was a big influence on my decision to take Selina that way when UDC rebooted.
Was that the whole thing where Batman got blamed for John Grayson's murder? Because I ran with that for a while with Dick before getting wrapped up in Titans shenanigans.
