"Yes, it was," Faith stated in return, a fraction more calmly than he had managed to speak. "You cheated. I'm sorry if that's hard for you to hear, or deal with or whatever, but it was an affair. The single, only difference if you'd actually fucked her would have been that I would have dragged your ass down to the nearest STD clinic before I let you touch me again. Every other element, it was there. And that's why I just can't believe that those first few months were real."
She could sense the looks from the other people over them both, her Slayer senses crawling under the scrutiny of the people, all trying to pretend they weren't looking at the strange couple arguing. It was hard to keep her voice down, to not scream and shout and maybe even cry, but she made herself do it anyway. "You're not a monster. And you're not a freak, not to me. But you were sneaking around, going off for days with a woman who openly despised me, lying to me about where you were, what you were doing. Your mouth was on her body and you were falling asleep in her arms. You were confiding in her in ways that you weren't talking to me, which wasn't hard because by the end you weren't talking to me much at all. Everything you were doing was calculated to keep me in the dark and you were yelling at me if I tried to get too close. So you tell me, aside from the fact you didn't stick your dick in her, how was that not the classic definition of an emotional affair?" Would that be enough? Would that make him see what he had really done? Faith wasn't even sure so she tried another approach.
"Okay, think of this for a moment. This city has no Champion any more. We're weaker, more vulnerable and we've got more dangers coming all the time. What if I found out that feeding the blood of a Slayer to one of the vampires with a soul was a way to make them strong enough to save all of us? To make Angel the Champion again, or give Spike what he needs to take that role. What if I decided to let Spike feed from me? If I started sneaking around with him, letting him get his fangs into my neck once a day? Aside from the fact that it's pretty dumb to let a vampire feed, are you honestly telling me that you wouldn't consider it a betrayal? That the idea of me being that intimate with another man wouldn't drive you crazy?" She wondered if the image she had tried to paint was vivid enough, the idea of being in the arms of the blond vampire as he bit into her. "And for the record if we did ever find out that the blood of a Slayer for a souled vamp would save the world, I would use a needle and draw it out that way, let him store the packets in his fridge next to the pigs blood with a twist of otter and weetabix stirred in for texture. I would never let him bite me, only you get to do that." She offered a faint smirk. It was frankly pathetic, but she was trying anyway.
"I do have to defend you," she corrected him. "That's part of the deal of standing by you, that I stand all the way, even through my own doubts, and I am trying to be more understanding. I've kept quiet even when you've been in some foul moods and I've known it's because you've been talking to her, but I guess I've reached my limit. As a Slayer I may be super whatever, but as a human I'm still just a girl, I'm still jealous and petty and whatever else human girls get like. And I want to be the only one you think about. I want to be the one you're obsessed with. I want to be able to trust that you're not hiding anything else from me because I just can't right now. It's starting with hiding messages, but where is it going to end? You blowing off meeting with me because you have to start stalking her to see what she's doing all the time? Or even further, will the secret messages turn into secret meetings, again?"
She bit the side of her lower lip, her body language tight as she shrugged slightly. "I wanna be the one in your head all the time, and I don't like having to share again."
