Damien smirked, still looking at the photo in the wallet. "Ohh, I think I can reach much farther than NASA...." Cryptic, perhaps. But it would have to do. And if Batman thought it was foolish or lame, then that also worked in his favor. "You don't kill.. huh. Hope you're right. Because killing is wrong. Some may think that the act of allowing a death is akin to murder. So.... not even a thank you for warning Nightwing about that other guy not being the Bart you all know. Ok, got it. Nice."
As to the reference on killing, he might have been referring to how Bart had advised his friend to not help him, according to what Virgil had said. But Damien didn't clarify or explain. Let him figure it out if he wished. He felt no obligation to express what he knew as a fact now. He looked down at his hand, which the scar was not so bad. He turned, hearing that last part, and he was going. "Ahh, but I will do nothing to you. I should. But I won't.. because that is the right thing. A man who forgives, as I do to you now, would err by doing you a wrong." He wasn't sure if the Bat heard that. Probably didn't. He wouldn't hurt him; no, that would be obvious. He had other ideas... other ways to take action, within the law and internetz.
The man looked at his desk at the phone. It could be easily replaced, as would the desk. He glanced at the clock on the wall and smiled, pulling the cellphone from his pocket... he always had a backup in place. He chuckled to himself, wondering if the other Bat would have done a better job of casing the area before engaging him. Which sort of gave him a clue to who this Bat was. He dialed a number. "Did you guys get that? The picture clear?" He nodded. "Yes, alright. Good to hear. Listen, do me a favor... you make some copies of it when I arrive. I'll be on hand to supervise. Yes, of course.. I will be down shortly."
He hung up and went to the widow, fingers running lightly on the crack. Damn.. he'd need to replace this too. Possibly look into electrifying the area around the glass too, in case this happened again. He stared into the night sky. Perhaps it was time he called on his followers, made a meeting. Set his house in order. He began to speak, though talking to himself. "No... Terry. I won't hurt you physically, so all of you may live within your flawed perceptions if you wish. Continue to hate, blame or accept faulty motions about me. I'm still right. You may never admit it, but I know it. Others may know it too, soon enough. And there may come a time when I might have a solution or an answer to a predicament.... and I will not be there."
