Juliet's POV-Hogwarts 3rd Year-The Feast

I sat by Harry grinning as we got into the Great Hall. As the Feast began I ate like I had never eaten before in my life. Hermione and Ron ate slowly looking up at the professors' table. I stopped eating and looked up; trying to see what was so interesting. It was a new teacher, but Dumbledore hadn't mentioned anything about him. He had short, brown hair that looked like he hadn't brushed it in a while and had on a long trench coat.

"He's looking right at you," whispered Harry in my ear. I looked at Harry and then up at the man, seeing him grin and wave at me. I waved back slowly.

"Who do you think he is?" I asked him, but Harry just shrugged.

After the feast I got up and went up to the Gryffindor common room with the rest of them. As Harry, Ron, Hermione, and I were comparing schedules I saw the man cut through the crowd, politely asking to go through. I stared at him again. I didn't know why, but I felt that there was something about this man. Everything about him made me want to talk to him, just one conversation at the least. It wasn't that I was attracted to him; it was just that he seemed different from everyone else. I felt harry nudge me and I looked up, seeing we were in front of the Fat Lady, and sighed.

As I sat in my bed that night I didn't feel tired or ready to even think of sleeping, so I let my mind wander. Every thought was about him. That strange man. He had no name, and I had never seen him before in my life, yet I knew that there was something about him. Everything about him was odd. Unusually odd, even for someone like me he seemed unnatural.

I woke up that morning, my glasses on my nightstand and my wand on my trunk. I didn't remember taking off my glasses or putting my wand at the end of my bed. I looked over, figuring it was Hermione and smiled slightly as I put on my glasses and got changed, keeping my wand in my pocket.

After many minutes of struggling with my shoe laces, as they were completely tangled, I walked down into the common room. I heard a noise behind me and looked back as I continued walking, bumping into somebody. I fell back and landed to the floor, hitting my head as I did. I rubbed my head and saw someone stick their hand out to help me up.

"Thanks," I muttered, feeling stupid for not paying attention.

As I looked up at the person I ran to I was slightly shocked. I expected them to be tall and muscular and a much older student, but he was actually in my year. He was slightly taller than me and had messy, black hair and bright, icy blue eyes.

"Hi, I'm Tom," He said with a lovely smile.

"Juliet Potter," I said shaking his hand.

His hand felt cold when I shook it, but I let it go. He was very nice and asked to compare schedules. I found out that we had every class together; he was even taking Arithmacy and Muggle Studies. I noticed that he seemed tense when our shoulders bumped slightly and he rubbed where our shoulders had touched. I noticed that Hermione was standing over me grinning. I looked up and smiled.

"Hello!" She said enthusiastically sitting by my and messing up my hair. I grinned and tried to straighten my hair back out. "Ooooh, who's this?" She asked seeing Tom sitting by me.

"Hermione, this is Tom. Tom, this is my best friend Hermione," I said smiling between the two.

Tom nodded slightly to Hermione and muttered something about wanting to go down to breakfast. I nodded as he grabbed his bag and schedule, leaving the common room. I giggled slightly looking over at him and Hermione squealed.

"He was so cute! You like him, don't you?" She asked grinning. I nodded giggling.

"We bumped into each other in the common room and he helped me up. He's so sweet! And we have very class together," I rambled excitedly. I explained everything as we headed down to the Great Hall.

I looked up as I ate breakfast as the new professor walked in and sat in his usual seat by my dad, who looked at him unamused as the man began to ramble excitedly. I shook my head and looked around. I saw Tom sitting across from me grinning. I smiled and laughed slightly as he made a face at me. Harry poked my arm as he sat on one side of me and Ron sat by Tom. I poked Harry back and he rubbed his arm, laughing. We all went back to comparing schedules, which we all had double Potions, double Divination, Care of Magical Creatures, and Defense Against the Dark Arts together, and then Hermione, Tom, and I all had Arithmacy and Muggle Studies. Hermione's schedule looked much longer than the rest of ours, but I didn't ask her about it.

That morning I sat by Tom in Potions class, and I made sure to be in the seats directly behind Harry and Ron. I looked up and read the board every so often, and smiled at Silveus as she looked back at me from the front, who smiled back and waved.

The morning went well, with the exception of Divanation being completely boring, and I was anxious as we ate lunch, Muggle Studies being our next class. Hermione, Tom, and I all began to discuss what we thought the professor would be like. We all agreed that it would most likely be someone trying to dress like a muggle, and not doing very well. As the bell rang for our next class we all buzzed excitedly as we walked up to class.

When we got there and opened the door I saw the strange man from last night grinning and waving us all in and telling us to sit anywhere. I stood in the doorway for a minute, and then, slowly, took my seat next to Tom and Hermione, completely shocked.
