From The Grey House:
Vincent watched as reality hit the human. His happy grin slowly fell into an open-mouthed scream. Aaron tried to escape, but Vincent had him in a vice grip. One hand was holding Aaron’s shoulder; the other was on his opposite arm. Aaron struggled anyway and, in his fear, succeeded in pulling his arm out of the socket. His fearful scream turned into a howl of pain. Vincent slowly pulled the man toward him, embracing him again. This time, though, he ripped Aaron’s shirt off his shoulder, opened his mouth wide, revealed his fangs and bit into the human’s shoulder. He drank deep and long, tasting the sweet saltiness as the hot blood filled his mouth, throat and his stomach. He drank his fill then let the man fall.
