"Now, you may feed. You may use a glamour to subdue your dinner completely. You may ravage her, on all sense of the word. You may rip her throat out - but that's not advisable in most situations. Or you may bite her, feed, and make it nothing more than that. You may make her feel as if she's riding the fucking waves of ecstasy. Or you could give her never ending nightmares." Pam didn't believe she was exaggerating as she said these things. She knew there were very gifted and twisted vampires who could make feeding rather interesting.

"Now sit with her and feed. Careful to take only what you need." She motioned for John to do as he was instructed, no glamouring involved.
