From Inside the Grey House:
Joseph understood what Natalia was doing before Vincent did and headed for the private corner. She had recognized someone. He didn’t know whom, but he needed to gather the troops. As he slipped by the crowd, he pulled out his cell and sent Mierka a text. In turn, she called the werewolves, who were waiting a block away with Lilly in another club. As he put his phone away, he heard Natalia yell a name he had not heard since the night they freed her.
Natalia recognized the man and hurriedly looked at the other faces. She locked eyes with the man again. “Dean? Dean! SLAYERS!”
The crowd scattered.
