Jean-Claude watches his charge disappear into the restroom with one of the patrons of the club and a small frown appears on his face. It's not that he disapproves of feeding on the human, not exactly. It's more that he knows what sort of unknown she is, as a baby vampire, knows that she won't be able to control herself, and knows that if someone finds a dead body in his restroom then that would be bad for business.

So he decides to step in himself. He'd been in enough trouble with the police when Phillip had been called out for the possession of dark magical artifacts. He didn't need any more Guardians knocking on his door.

Stepping forward and swinging into the bathroom behind her, he takes stock of the situation before him before he states, as calm and coolly as he can, "I suggest that you let him go now, ma petite souris."
