She knew it was bad. She knew what she was doing made her less good. Because she *knew* Faith was evil, but she kept going back. Damned if she knew why, if she could explain the thrill of going to see the other Slayer with the knowledge that her friends would disapprove and that it would break Angel's heart if he knew. That each time she went, Faith might snap and kill her. It was wrong for her to want Faith, bad of her to risk her life, and therefore every life in Sunnydale, each night, but she did. Because she wants it, and Faith wants it, and fuck the rest of them because come nightfall she will be going back, because she is a human being as well as a Slayer. Because even though every time she leaves Faith's she swears it'll be the last, she always goes back.

Because she needs it.
