Okay first off replies to reviews:

theyellowone I'm sorry but Ron will have to stay suspicious for the plot to work but here's my reasoning. Voldemort has just been revealed to be back so he can no longer hope that he won't do anything just to remain hidden. And also four new kids not in first year when parents are taking their children away from Hogwarts? You'd be suspicious, as well as this so far he only mistrusts Nico and you've got to admit he is a bit creepy sometimes. Also I meant to mention at the end I just needed Harry to be at the airport. It can be for whatever reason you like: Dursleys dragging him there to meet Aunt Marge or him meeting Hermione as she comes back from holiday it isn't going to affect the plot.

Also thanks to the following for reviewing: trinigyal123, theyellowone, meminisse iuvabit, MacBud94 and EmilyNight117.

I just realised that I should be writing a script for History right now but I think I'll continue. Oh one last thing from now on I'll try to update at least once a week.

Disclaimer: I (unfortunately) do NOT own Harry Potter or Percy Jackson. If I did then no one would have heard of it and I wouldn't be writing this.

Chapter 2: A talking hat sings and screams.

Hermione's POV

We were in the great hall and Dumbledore was talking while we waited for the first years to arrive when the people from the train came in. They were speaking in some kind of weird language and most of them were complaining by the sound of it. They were carrying what looked like a tent on their shoulders and each was balancing a trunk on their shoulder. Trunks are always heavy not to mention the tent but they seemed to think it was nothing. In the candlelight I noticed that the blonde haired girl and the black haired boy both had streaks of a faint greyish silver in their hair.

Percy's POV

We had skipped the carriages that were there and gone straight to the grounds. We were planning on camping in the forest and going up to the castle the next day. But before we could set up the tent a man named Hagrid came and told us we'd better get to the castle. Then we started a conversation about where we were going to sleep. "I am not sleeping in a dorm. It's going to be hard enough to pretend I'm a wizard without having to do it all the time," stated Nico.

"I agree, plus if I have to spend one more minute than necessary with stupid boys I will blow my top!" replied Thalia

"We'll need to train," said Annabeth. We were talking in ancient Greek so as to avoid suspicion and this discussion continued until we reached a giant hall. Nico was the first to notice; he coughed to get our attention and whispered that everyone could see us. I noticed that people were giving us odd looks about the trunks again.

3rd Person Narrative

The whole hall was silent and staring at the four people who had just walked in. Dumbledore, sensing the confusion, stood up. "I would like to welcome our American transfer students who will be staying for the year. If you would like to come to the front to be sorted." He motioned to the four of them. As they did Percy whispered to Annabeth "Does he know?" she shook her head.

The students all seemed to lean forward in their seats, eager to know who they were. Professor McGonagall took out a roll of parchment and started to read off names. She came to Chase, Annabeth and she strode towards the stool. The hat had been on her head for about a minute when it started screaming. "SO MUCH FACED! BETRAYEL! DANGER! ... MUST BE GRYFFINDOR!" The hall was astounded but still clapped harder. Next was Di Angelo, Nico, it took less time for the hat to start screaming this time. "TOO MUCH! FAR TOO MUCH! TOO YOUNG!" the hall was silent for a moment before they managed to start clapping. Soon after it was Grace, Thalia she strode up with an air of carelessness. There was the same result and reaction as Annabeth for her. Finally it was Jackson, Perseus. The hat had barely touched his head before it screamed. "SO MUCH PAIN AND SUFFERING! SO MUCH RESTING ON THESE SHOULDERS! GRYFFINDOR!"

There was silence. Percy walked slowly towards the Gryffindor table. He gave Annabeth a kiss and McGonagall resumed the list of names.

Percy's POV

When the woman, McGonagall, had finished Dumbledore stood up and said some random words and told us to eat. We looked around for a fire, there wasn't one. "Do we have to?" asked Nico. "You know the rules, no sacrifice no food. We'll talk to Dumbledore later," replied Annabeth. Personally I did not want to risk offending Zeus. So we just sat there, getting some strange stares from people- particularly the redhead that had been on the train. Then the girl spoke up. "Hello, I'm Hermione Granger. These are my friends Ron Weasley and Harry Potter." The guy named Harry Potter had an intake of breath when she said his name as if he was waiting for some reaction. "Oh," I said, "I'm Percy Jackson. This is Annabeth, Nico and Thalia." Hermione asked us how we knew each other. "Thalia and Nico are my cousins and Annabeth is Thalia's cousin." Then she started to bombard us with questions about our school which we answered as best we could but most of it was lies.

Suddenly Ron said "What have you seen?"

"What?" asked Annabeth.

"You all made the hat scream, and I saw someone take it to the hospital wing. It's never done that before. Anyway, you're only our age! No one has seen enough to make it do that before, not even Harry!"

"You'd be surprised," I muttered darkly.

Ron's POV

The American transfers sat down near to us. "They have weird names, don't they." I whispered to Harry and Hermione. They nodded in agreement. The food appeared on the table and I was tucking in when I noticed them looking around for something. Then the boy called Nico said something and Annabeth shook her head and they sat there while everyone else ate. Nico looked grumpy but, what's his name, Perseus looked nervous.

I was wondering about how they could have made the sorting hat scream and was about to ask them but Hermione jumped in and started interrogating them about their school. After a while I decided just to ask them. The Percy dude just muttered 'you'd be surprised.' I glanced at Harry but he just shrugged.

Dumbledore told us to go to bed but the transfers walked straight up to the head table and started asking something. Dumbledore nodded but looked confused and they marched back to the table and picked their trunks- God they were strong- and followed the line of Gryffindors going towards the common room.

I turned to the others, "there's something wrong with them." I stated, to my surprise Hermione agreed with me but when I asked her what she just bit her lip and said "I don't know." We went up to the common room and saw Percy fast asleep on a chair next to the fire. But didn't he go to sleep on the train? For some reason I decided to wake him up. I went up to him and shook him. He lunged at me, quicker than he should have been able to, with a pen. Then he saw it was me and rolled his eyes as if I wasn't worth it. "I need to sleep or I'm going to collapse," he announced. I was confused he had been asleep just then and on the train, why was he still tired. But then again maybe he was just weird like that.

The next morning I woke up at eight – surprisingly early for me – and went into the common room. And the transfers were there! They were bounding up and down as if they had been awake for hours! I decided to ignore them and dozed by the fire until Harry and Hermione got up.

Thalia's POV

We waited until around eight and then Ron came down to go to breakfast. We figured that we wouldn't be able to have a conversation without being listened to. Unfortunately Harry and the nosy one – Hermione – came down just as we were leaving and went as well.

When we got down Annabeth looked at Dumbledore and he nodded and did some strange thing with his stick and a fire appeared. We all piled our plates and gave our sacrifice. Ron looked at us as if we had committed some sort of crime. But we had long since decided that we were just going to ignore any stares. I looked at our timetables. Oh Gods. They were in English. "How in Hades are we going to read them?" I hissed. Even Annabeth couldn't think of an answer for that. Just then a hand shot out and grabbed my timetable, the air crackled at my annoyance. "You see to have most of the same classes as me." said a bossy voice. I bit back my flash of anger and asked what we had. "Potion, Herbology, Defence Against the Dark Arts, Transfiguration, History of Magic, Astronomy, Charms, Care of Magical Creatures, Divination – but that's with Harry and Ron, and Ancient Runes with me." With that she walked away. I was relieved that she hadn't started questioning us. We jotted own the lessons in ancient Greek beneath the English. Then we ran to our dormitories and grabbed our books.
