So, I’ve long maintained that ‘Ric’ is actually a clone of some sort because do you really think BATMAN would let his eldest son out of his sight if he was SHOT IN THE HEAD?! No, five bucks says he’s got him squirrelled away in a super secret hidden section of the Batcave, or the Fortress of Solitude. Hell, I wouldn’t be surprised if he somehow found a way to Themiscyra if it meant saving Dick’s life.
Then, I got another idea. Anyone remember the Wedding Prequel Comic: Nightwing vs Hush? And how Hush now has Dick’s face? …Do you see where I’m coming from? How does he have amnesia? His brain was probably messed with and Alfred and Barbara thought he was Dick because Bruce didn’t tell them.
Granted, I haven’t read the Nightwing series since he got shot so this could be complete baloney, but it seems more plausible than Dick just turning his back on everything and being an ass.
