That was... unexpected. A look of distaste passed on Damian's face but he took advantage of the situation all the same. He used the distraction to sheath the sword he had grabbed and pick up his own sword from the rooftop. It really was past time he paid a visit to Catwoman.
Damian smirked and nodded to the closest group of ninjas as if to beckon them forward. It was important to control the flow of the fight and not let your opponent dictate the pace. This would be a good test. While the forces might have number, Damian doubted they had much skill.
He spared the girl one last glance before turning his attention to his own fight. She was of no concern. She had been the one foolish enough to invite herself. Although, Damian did try to keep an eye on her, just in case she had her own agenda.
