His B is a piece of shit. Abandoned him when he really needed someone's support.

( because dick grayson died and everyone, including damian, blames him. )

Beats the shit out of him when they cross paths, too. He's got his reasons, they're--I can't blame him any. Hell, I've wanted to kill my B before.

( a loose shrug, before he reaches out and places a hand on dick's shoulder. )

He won't kill the one here. Probably.
