Original image was a still frame of the episode quoted, until I read that you can't post images from movies/tv. So I posted this generic pic.
Moving on...
I am not trying to bring Buffy to FA. I just REALLY love this quote. It stirs something inside, and, considering that there are so many that can howl on this site, I would assume that it would reach something inside all of us here on FA too.
I just have to source the quote, so that I'm covered.
So here it is:

“Passion, it lies in all of us, sleeping, waiting. And though unwanted, unbidden, it will stir, open it's jaws, and howl.” -Angel from the second season of Buffy the Vampire season, episode entitled “Passion”.
