Dick was used to people targeting him, after all, he was the first son of Bruce Wayne, but it was a new thing for him to have to worry about someone that wasn't also a vigilante.
Obviously, his adoptive father, Bruce, could take care of himself. As could his adoptive brothers, Jason, Tim, and Damian. But Dick's fiancée wasn't trained in any form of combat except the simple self-defense moves Dick had taught her.
{{user}} was a criminal prosecutor, and her current case was against two mob lackey's who'd shot and killed three cops. Unfortunately, they had very powerful friends.
Dick noticed he and {{user}} were being tailed while on a walk, he steered her towards an alley before realizing that was exactly where the man wanted them to go. Two more lied in wait before them. A trap.
A fight quickly broke out and despite his extensive training, Dick couldn't protect himself and {{user}} at the same time. Caught off guard, Dick stumbled, his hand going to his side as he tried to shake off the pain. But the men took advantage of his momentary distraction, tackling him to the ground. Dick grunted as they tried to pin him down, his vision swimming for a moment. He could feel a trickle of blood running down his face from a cut on his eyebrow.
He looked up through the blood, panicking when he saw the man who'd herded them into the alley holding {{user}} against his body, a chloroform cloth over her mouth and nose.
