"Change of plans." Was all he said in response. His arms folded uncomfortably as he stared him down. He didn't want to involve his circus anymore if he didn't have to. It was his parents circus, the way Dark did business would not only disgrace them but himself. That was something he wasn't sure he could live with. He'd already suffered so much since their murder. "Partnerships are not formed over night Mr. Dark." He said softly. Concerned eyes on the train. He was known for making rash decisions, maybe this was one of them. But he had to help those who had been abducted. Clint told him he was on Dark's grounds, Dick was almost 99% sure it wasn't of his own free will.
"Give? I'm sure you don't mean money." The vibe he was getting was making him suspicious. At this point he didn't have much choice but to negotiate with him. Bruce had always taught him not to negotiate with psychos, but it was a more delicate situation then that. The carnival was built on fear, how did one defeat fear, they confronted it. This was the best way he knew how.
"What would you want?" He asked hesitantly. He knew people had to be getting anxious by now, but a rescue operation of large scale proportion would only end badly at this rate. Who knew what would happen.
