Chapter Fifteen

"So I heard that you have to help put up decorations," Ginny said to Harry.

"Don't remind me," Harry groaned, "I have an insane dark wizard that I turned into a werewolf, several victims, two that Ron doesn't care anything about, and I know that Peeves is going to do something to cause us problems."

"Glad I'm not a Prefect," Ginny stated and Harry gave her dirty looks.

The Defense Against the Dark Arts teacher, Professor Kowalski, was piling on homework that Harry was sure that he would never get done. Transfiguration was getting harder since they were learning how to vanish things. Hermione had gone to vanishing pigs.

"Do you ever wonder where they go?" Harry asked Hermione.

"No," she answered.

"Imagine if those pigs landed in the house of someone that hated meat," he joked and Hermione snorted with laughter.

Halloween came around and Harry found himself the subject of one of Peeves pranks. He rained down colored water that turned his robes, skin, and hair blue. Harry looked at Peeves with hate, deciding that, if he was alive, that would be one dead man. Since what Peeves had done would make him the target of being made fun of, he really wasn't in the mood for that, he went to his father's office.

"Dad, it's not funny," Harry said as his father burst out laughing. "I come for support and I get mockery."

"Sorry, but you look like a smurf," he said, snickering.

"Oh I'm so disowning you," Harry said.

After a series of embarrassing 'photo's which Harry thought had to be the most embarrassing aspect of having a father he was back to normal. Harry made a vow that he would find those photos and burn them. He decided that he would stay at Hogwarts then having to hear the staff laughing at what Snape had taken. Halloween came around and Harry's mind turned to the event that he couldn't escape from.

Changing into a werewolf!

The next night Harry, Hermione, and Draco were taken down to different rooms that had all been warded to prevent them from escaping until the moon waned. No sooner had the moon appeared but Harry felt the pain begin. He screamed as his bones broke, lengthened, and then fused. His nails grew, hair appeared all over his body, his face changed form, and then it was over. Harry curled up and went to sleep.

"You're a bad person," McGonagall told Snape.

"I need to have a bit of fun," he told her and McGonagall rolled her eyes.

"Their locked away," Madam Pomfrey reported.

"Let's just hope that Tom doesn't attack anyone else," Dumbledore told them, "Only then will I be able to sleep."

"You think that you can defeat me, Harry Snape," said the cold voice inside Harry's mind.

Harry's wolf form growled and then Harry said, "You will be bowing to me, Tom Riddle."

"Don't call me that," Tom snarled.

"Oh I'm sorry did I remind you of someone that you hate," Harry taunted and then Tom whimpered as Freki made his presence known. "I made you; I created you, YOU WILL BOW TO ME, MUTT."

Tom vanished and Harry's dreams were pleasant.

When Harry woke up he was back to normal and Madam Pomfrey was walking in. She put a robe around him and led him out, his body shaking. Soon he was cleaned up and in bed. Madam Pomfrey waved her wand and Harry went back to sleep. Three days later Madam Pomfrey allowed them all to leave. When he got back to the common room he found out that Gryffindor had won the match against Slytherin.

Malfoy wasn't going to be happy about that.

"Little dragon, it's not your fault," Snape told Draco.

"If I wasn't like this then we could of won," he said.

Snape put a hand on his shoulder and said, "Tom Riddle will get what's coming to him. Trust me on that."

"But what if he's never caught?" Draco asked.

"Trust me, he will be caught," Snape vowed and Draco left.

"Upset that he wasn't able to play," Dumbledore figured out when Snape told him what had happened.

"Do you blame him?" Snape asked him.

"No, I don't," he said.

"Did Tom attack?" Snape asked him.

"Nothing that the Ministry reported," Dumbledore said, "Tom is most likely healed and is on the move. Let's hope that he makes a mistake and the Ministry can catch him."

Snape hoped so as well.

A/N: For those that are wondering. Professor Kowalski, in my story, is the grandson of Queenie Goldstein and Jacob Kowalski. He's brought in because Dumbledore can't find a British wizard, or witch, to take the job. Another note: Sorry about the delay. I've just been really busy.
