Any self-respecting billionaire playboy would have responded to the sound of a gunshot by hitting the ground and panicking. He didn't do that. His head whipped around to the direction the shot had come from, either while their other guests were screaming and panicking. He saw someone running through the crowd and tensed to follow but caught sight of Tim, bleeding first and put it off. One hard look would let him remember the person's face, build, movement. Later.

Tim was way more important to him Tim bleeding made his heart stop and then race, and that was... damned unusual as a lack of control. His sprint took him to her, hand clamped over the wound in her arm hard, and he more or less yelled for someone to call the police. What he could do with this right now - Bruce Wayne had been attacked, not Batman. (Or Timothea Wayne, not Robin).

Then he turned his attention back to Tim. "We're going to the floor, okay?" Better for blood pressure.
