Chapter 7: Lessons and Aunt Petunia

Harry's POV

The first week at Hogwarts was exciting and nerve racking. Since we both knew how to get to class we ended up having to take Hermione with us so that she wouldn't get lost. Monday was Transfiguration, Magical Theory, and Herbology. Professor McGonagall gave me a stiff look when I entered and I knew that it was due to the fact that I wasn't in Gryffindor. I was the only one to fully transfigure my match into a needle and she only gave me a single point.

The other ravens thought this was totally unfair.

"You managed it and we get only one point," one of them said.

"It's because I'm not in Gryffindor," I told them.

"Oh great, she's got mental issues," another said.

Thankfully she wasn't around when that was said or that person would have ended up in detention. Magical Theory was better than Transfiguration. Professor Pike had no problem giving me points when I asked a question, leaving Hermione a bit put out. During lunch I decided to address the issue.

"Hermione, I've been studying magic for years," I told her, "Just because I know the answer doesn't mean that I'm dumbing down others."

"But I know the answer too," she moaned.

"Hermione, you're going to get bullied if the students think that you're a Know-it-all. Sometimes it's good to leave alone the fact that you know things. My mum was muggleborn and was very smart and talented. I'm sure that she didn't spout off answers every time that she could. Being smart is good but it's not everything."

"Well I don't care," she said, backing away, "I want to prove that a muggleborn can do it just as well as a Pureblood."

And she stormed off.

"I've got a bad feeling about this," Dudley stated.

"Yeah, me too," I said, agreeing.

Hermione didn't talk to either of us for the rest of the day. She was bunkered down with books, working on the homework that Professor Sprout had handed out. We were working as well, so that we didn't get detention for having late work. The next day we had double Potions with the Hufflepuffs and then Defense Against the Dark Arts. That class was enough to give me the creeps. Professor Quirrell caused everything in me to go on high alert.

When he turned his back on the class to write something down I focused on him and he suddenly gave a horrible scream and whipped around.

"P-P-Potter, detention," he said.

"For what?" I asked him.

"Because I feel in t-t-the mood," he answered, "Now, get out."

I was more than pleased to do that.

When the rest of the class returned Hermione at once was on my case. I head to hear her say that I had no right to do whatever I did to him.

"There's something wrong with him?" I told her.

"Yeah, right," she hissed, "Just because you're the famous Harry Potter doesn't mean that your word means anything. You got us twenty points taken from our house for whatever you did."

"You know what, Hermione, leave me alone," I said, "I know what I'm talking about and you need to get it that this isn't a regular school."

"Harry has a point," Dudley said.

"And I don't care," she said, "You will tell Quirrell that your sorry."

"And you're not my Head of House," I countered and I stormed off, mad that she was treating what I felt, and got a reaction from, lightly.

I decided to IM my aunt, to let her know what had happened. I found her baking something and she turned when she heard my voice.

"Harry, I thought that you were going to write to me," she said.

"Sorry, aunt, but we have a problem," I told her.

"I do not like this," she stated, "What kind of problem?"

"A Tom Riddle problem," I told her and at once she was on alert.

"Tell me everything," she demanded and I told her what happened during Defense. "Vernon and I will be there at once. Do not go near his office."

"Trust me, I won't," I said and I broke the connection.

Petunia's POV

"Vernon, Harry is in trouble," I told him and he looked up from his book called 'The Art of War.'

"What did Harry do now?" he asked.

"Your father's thorn is at Hogwarts and Harry sniffed him out," I told him.

"I'll get the rifles," he said and he left.

"Make sure there the endless celestial bronze bullets," I told him, "I'm not allowing that horrible man to hurt Harry or Dudley."

"Those are the only ones that I have," he said and he hurried out of the room.

Ten minutes later we were both at the school and we marched to the Defense office. Vernon had summoned two hellhounds to help us out.

"By time that we're done with him he'll be begging for death," Vernon told me.

"Good," I said, "Time to squeal like a little piggy Tom Riddle."

We found the door and I blasted a hole in it, making the man scream. I pressed my face through the hole, "Here's Petunia." I blasted it open and took a shot at the man.

"Hounds; play fetch," Vernon ordered and the hounds bolted through.

They had him cornered and he looked at me with a look that made me point my riffle at his face.

"You think that you can defeat Voldemort," he snarled.

"Oh I know that I can," I hissed, "I'm going to see you suffer, Tom Riddle, just like you made my nephew suffer. You murdered my sister, you pile of goat droppings, and that's a moral crime in my book."

"And your defying death," Vernon added, "I think I'm going to blow his stomach off."

"Oh please," I said, "I just love the smell of stomach in the evening."

"What the-."

I turned to see Dumbledore standing there, which made Tom push me down. I pointed my riffle at him and blew his leg off. He screamed in pain and then I got up and walked over to him.

"Vernon, I think that you know what to do," I said.

"Furies," he called out and three women appeared.

"Oh look, the mortal that defies death," one of them said and she picked him up. "You're going to Tartarus, Tommy, and you're going to like it."

He screamed as he was taken away.

"Rifles," Dumbledore said, "You brought guns to the school."

"They won't kill a mortal," I told him. Anyway, needed something that he couldn't block with magic and get away from us!"

"I hope that you intend to pay for the door and the desk," he said.

"Oh don't worry about your pretty door and desk," I told him and I waved my hand and everything repaired itself.

"Sometimes I really wonder," he told me.

"Oh by the way, I'll be teaching defense," I told him.

"What! Why?"

"Do you want to explain to the governors how Quirrell suddenly vanished?" I asked him.

The look on his face told me, no.

Harry's POV

"You blew Quirrell's leg off," I said when I went for detention and found Petunia standing there.

"I sure did," she said, "You should have seen me."

"Aunt, you kick butt," I told her.

She laughed and said, "Thanks, and you're not so bad yourself."

I thought it would be interesting that Vernon is reading this book. I thought it would be funny for Petunia to take a quote from the movie 'The Shining' where the manager says 'Here's Johnny' and she replaces it with Here's Petunia. Thanks for your reviews and for reading. I will post the next chapter tomorrow.
