Granted I didn't have much faith in King but damn.
Minor SPOILER AHEAD
First of all Bruce doesn't say sons he says son. Implying he doesn't see Dick and Jason as his kids despite years of stories saying otherwise.
Second of all bringing up Damian alone makes it sound like he's the only one that really matters.
Third of all Bruce has lost all of the boys in some way prior to this. Jason and Damian actually died, Dick was stuck being a spy for awhile and Tim is currently considered dead. Way to miss the point of the bat family and at a time Bruce should be worried about ALL of them.
EDIT: This same crap just happened in Nightwing?! Dick calling Damian Bruce's true son. Well I shouldn't be surprised that King and Seeley wrote this nonsense.
