He screamed. It hurt everywhere. His whole body was on fire and he couldn't move to put the fire out.

He slowly crawled to the couch. Lying down, he began to pant. Another cramp in the stomach made him double over in pain. At least this time, he was lying down, so he didn't fall to the floor again.

Groaning, he heard the door slowly open and was just in time to catch the back of Hermione's head as she closed the portrait into his room. Something in him took over, because suddenly he automatically quieted himself and hid himself further in the couch.

He could hear her heart thundering in her chest, each beat making him all too aware of how close she was getting to him. He closed his eyes, feigning sleep, as he heard her walk over to the couch. He heard her bend down to pick something up.

Not being able to stand the noise anymore, he pounced from the couch and stood in front of her. "Hermione. Make it stop." He whimpered. She immediately walked toward him wanting to know what is wrong.

He almost fell again as another cramp took him over. "Stay away. The vampire is God, I don't know. It hurts everywhere."

Hermione suddenly got a scared look in her eyes. The fear that Harry could smell made him fall off the cliff he was balancing on and he lunged for her. Just as he grabbed her, the door opened again and Ron poked his head in.

Stopping, Harry looked to his best friend, baring fangs. Hissing loudly, Harry held Hermione up and turned her around so that her back was against his chest. Twisting her head to one side, exposing her neck, he began to pant with the need of blood. He was happy to see Ron run away, leaving him to his meal, struggling in his hands.

"Harry, please don't." Hermione gasped, as she felt needle sharp teeth graze her neck not enough to draw blood.

"Please." Harry whispered into her ear. As he reared his head back to strike deep, he was suddenly doubled over and lost his grip on Hermione. Clutching at his stomach, he looked angrily up at her. "What was that for?" He croaked, winded from where she had just elbowed him.

"You can't just kill me Harry." She replied, running to the tapestry and trying to get it open to get out.

Harry looked at her confused for a few seconds. "I wouldn't do that, Hermione. I just want the burning to stop."

"You will Harry. It's too strong. You won't be able to stop."

Harry looked at her more closely and came back to his senses. He slowly backed away from the way out. His eyes kept on flicking over her neck, making the hunger inside him flare even stronger.

Closing his eyes hard, he tried to clear his mind more, but was pulled once gain by the thunderous sound of her heartbeat. When his eyes opened once again, they found Hermione in much the same position she had been in before she had elbowed him.

Leaning down, he was about to sink his teeth into her flesh, when the tapestry opened and Ron, doing a very Gryffindor thing by being brave, tackled Harry to the floor. A wild struggle between the two boys broke out and soon Harry was sitting on top of his best friend’s chest, fangs burying themselves in flesh.

It took a few seconds of furious sucking, before Harry realized that his fangs were buried not in his friend's neck, but in a wrist. Grabbing the wrist, he held it closer to his mouth, digging deeper with his teeth.

Harry didn't even bother to hear the conversation that was going on around him. He was too caught up in the blood to do much of anything except take as much as possible into himself.

He did realize he was being picked up, however. And the absence of two of the heartbeats. Slowly, he came around to his senses. Slowly he let go of the wrist, only to see that it was Snape that he was clinging to. Could another vampire really feed off another? Harry thought and realized what a stupid thought it was. If it wasn't possible, he wouldn't have and both Ron and Hermione would be dead.

Glaring furiously at the man, he wriggled out of the embrace that held him and fell to the floor. He quickly got to his feet again, fists balling at his sides. He lifted a hand and pointed it at Severus. "I hate you for this. I hope you know that." He said angrily, before stalking off to his bed and laying down.

He couldn't believe he had gotten so out of control that he had purposefully tried to kill his two best friends. Hearing Snape sigh and slowly leave, Harry did the one thing he had been desperate to do since he was brought to Hogwarts that year. He curled himself into a ball on his bed and cried.
