She hissed like a cat, and raked her nails across my face, scoring my cheek in three lines of fire. I cried out and fell back, the wall interrupting my retreat.

"I can always tell, when I'm like this," Justine said. She gave me an abruptly careless look, turned on the balls of her feet and walked several feet away before stretching and dropping to all fours, watching me with an absent, disinterested gaze.

I stared at her for a moment, feeling the heat of the blood welling in the scratches. I touched a finger to them, and it came away sprinkled with scarlet. I lifted my gaze to the girl and shook my head. "I'm sorry," I said. "God. What did they do to you?"

"This," she said, carelessly, thrusting out one hand. Round, bruised punctures marked her wrist. "And this." She held out the other wrist, showing another set of marks. "And this." She stretched out her thigh to one side of her body, parallel to the floor, to show more marks, along it. "They all wanted a little taste. So they got it."

"I don't understand," I said.

She smiled with too many teeth, and it made me uneasy. "They didn't do anything. I'm like this. This is the way I always am."

"Um," I said. "You weren't that way last night."

"Last night," she snapped. "Two nights ago. At least. That was because he was there."

"Thomas?"

Her lower lip abruptly trembled, and she looked as though she might cry. "Yes. Yes, Thomas. He makes it quieter. Inside me, there's so much trying to get out, like at the hospital. Control, they said. I don't have the kind of control other people have. It's hormones, but the drugs only made me sick. He doesn't, though. Only a little tired."

"But-"

Her face darkened again. "Shut up ," she snapped. "But, but, but. Idiot, asking idiot questions. Fool who did not want me when I was willing to give. Nothing does that. None of them, because they all want to take, take, take."

I nodded, and didn't say anything, as she became more agitated. It might have been politically incorrect of me, but the word LOONY all but appeared in a giant neon sign over Justine's head. "Okay," I said. "Just … let's just take it easy, all right?"

She glowered at me, falling silent. Then she slunk back to the space between the wall and the washing machine and sank into it. She started playing with her hair, and took no apparent notice of me.

I got up. It was hard. Everything spun around. On the floor, I found a dusty towel. I used it to sweep some of the grime off of my skin.
