The howl got exactly the reaction that Jack had wanted: people scattered. Not all of the people, obviously, but it thinned the herd considerably. He had a moment of guilt about the fact that he had scared some--relatively--innocent people, but they'd probably be fine. It was Red Light. This sort of thing happened at least once a month if not more he was sure.
While Dom went and did what she did best, the Werewolf turned his attention to locating and assisting the strange man. Who was actually not doing that bad on his own. His fighting style was flashy that was for sure. While the man dealt with the soldiers in his way, Jack preferred a simpler method namely just grabbing them and then hurling them as far away as possible.
Which didn't do much to stop the spray of bullets one of the soldiers, a startled boy who couldn't have been much older than Jack when he first got infected, sent his way. The Werewolf howled again, in pain this time, as the bullets bit into him. They would heal, but it still hurt. When he roared and turned his angry eyes on the boy, the soldier dropped his gun and sprinted off the other way.
The tang of more blood in the air caught his attention, and he turned to see the strange man take down a solider and then drop to his knees, bleeding somewhat heavily. Taking a step toward him, he held out one giant paw. They were clear for the moment, but that wouldn't last. They needed to get off of Red Light as soon as possible. "I can understand if you're a little hesitant about this, but my friend and I would really like to help you."
