Harry's PoV.

I woke up on the compartment floor, confused and feeling like I have the flu. My friends were leaning over me and relief filled their faces when they saw me awake.

"What happened?" I asked them as I tried to remember how I ended up on the floor.

"Thank goodness you're all right." Hermione said as she and Ron helped me back into my seat.

"Where's that thing? Who screamed?" I asked them and they shared worried looks.

"No one screamed, Harry." She told me softly. "But..."

"But what?" I demanded. "What happened?"

"Well, that thing came and I thought you were having a fit or something." Ron said, looking scared. "You fell out of your seat and started twitching and you were unconscious."

"Professor Lupin told it that none of us were hiding Sirius Black and to leave but it didn't. So he muttered something and something silver shot out of his wand and hit it and it turned and glided away." Hermione finished the story.

"Did anyone else pass out?" I asked and they hesitated a moment before shaking their heads. Shame started to fill me. Of course it had to be me that fainted and not someone else. Then I realized something. "You hesitated, did something happen to someone else?" They gave me a pained expression. "Who else?"

"Percy Jackson, we didn't want to worry you." Hermione told me, desperate that I not be mad at her. "Though from what I've heard he didn't exactly pass out."

"What happened to him?" I asked and she opened her mouth to reply but was interrupted by the compartment door opening. Professor Lupin stepped inside sporting a new bruise on his jaw as if someone had hit him. He gave me a slight smile when he saw me.

"Glad you're awake, Harry. We'll be there in a few minutes. How are you feeling?" Lupin asked as he sat down across from me.

"I've been better." I answered before jumping into my own questions. "What was that thing? Hermione told me about Percy, is he alright? He isn't hurt is he?" The man held up his hand and I stopped talking.

"That was a dementor, from Azkaban. It was searching the train for Sirius Black." I started to ask him about that but he cut me off. "No, he wasn't here but they had to make sure. Mr. Jackson will be alright and no, he was not hurt. Though I will say that he has quite the right hook." He said, rubbing his bruised jaw.

"He hit you?" That shocked me.

"Whereas you passed out, Percy had a more violent reaction. He had a panic attack, I guess you could say. Dementors force you to relive all of your worst memories. Being trapped inside a memory, he most likely had no idea what he was doing."

"How bad of a memory would it have to be to get that type of reaction?" I whispered.

"My guess would be abuse, but you'd have to ask him. Though, I would wait until you've gotten to know him a bit more. Ask him before he's ready and he'll shut you out."

We sat in silence for the rest of the train ride. When we pulled into the station, everyone swarmed to get out. Outside, cold rain was pouring down on us. On our way to the carriages we waved to Hagrid. Though nothing was pulling the carriages, they still moved like they were being pulled by horses, jolting and swaying. Eventually we stopped and Ron and Hermione got out first. As I was getting out I heard the drawling voice of Draco Malfoy. He was standing just outside the doors to get inside the school.

"Is it true that you fainted, Potter?" he asked with a wicked sneer. I glared at him.

"Don't you have something better to do?" Ron asked, looking angry.

"What about you, Weasley?" He asked turning to the redhead. "Did you faint as well?"

"Shove off, Malfoy." I told him.

"Or what?" He sneered. "You'll faint again?"

"Is there a problem here?" A mild voice asked. We turned to see Professor Lupin stepping down from the next carriage.

"No, Professor." Draco grumbled and he marched up the stone steps with Crabbe and Goyle at his heels. Hermione pulled Ron and me up the stairs with the rest of the students and into the entrance hall. Just as we were about to go into the Great Hall I heard someone else call my name.

"Potter!" I saw Professor MaGonagall calling over the crowd. "Potter, Granger! I want to see you both." Slowly we managed to push through the crowds and were standing in front of her. "Move along Mr. Weasley. I only want a word with them." She said before ushering the two of us and another person away from the rest of the students. She led us up the stone staircase and along a corridor. I looked over to the other person with us and I was both glad and worried that it was Percy Jackson. He looked a bit pale and his hands were shaking slightly.

"You ok, Percy?" I asked him softly. It took him a moment to look at me and reply.

"I'll be fine." He said and I heard his voice crack a bit. "Thanks for asking." MaGonagall let us into her office, which had a large, welcoming fire, and motioned for us to sit. Percy immediately went and sat down next to the fire, holding his hands near the flames to warm them up. Hermione and I sat in the chairs as MaGonagall settled behind her desk.

"Professor Lupin sent an owl ahead to say that you two boys were taken ill on the train." MaGonagall told us.

"To put it lightly." Percy mumbled from his position next to the fire. There was a knock at the door and Madam Pomfrey walked in. I felt even more embarrassed that everyone was making a big fuss, since it was already bad enough that I had passed out.

"I am fine," I told them. "Honestly."

"I'll be the judge of that, Mr. Potter." Madam Pomfrey said as she checked my temperature. Chuckling sounded from the direction of the fireplace.

"Yeah, yeah. Laugh it up while you can, Jackson, because you're next to get looked at." I told him and Madam Pomfrey switched to checking my pulse.

"What dangerous thing have you done this time?" the nurse asked me disapprovingly.

"It was a dementor, Poppy." Professor MaGonagall told her grimly and they exchanged dark looks.

"Why was that thing even there?" Percy demanded, standing up to join us.

"What do you know about Sirius Black?" MaGonagall asked him.

"He escaped from prison and all of you think he's coming here." I was surprised by his knowledge, as minimal as it was.

"Yes, well, the dementors are the guards at Azkaban, the prison Black escaped from, and so they are being stationed at all the entrances to the school to make sure he doesn't get in and to hopefully catch him." The Transfiguration teacher explained. Madam Pomfrey finished with me and moved towards Percy but he stepped away from her. She tried again but he backed up even further.

"Oh, really, Johnathan. I only need to give you a checkup. Make sure you're alright and such." Pomfrey told him, sounding slightly exasperated.

"I'm cold, I was pretty much forced to relive all of my worst memories just a few hours ago, blacked out and hit anyone that touched me because of my fricking PTSD. Checkup done. Can I go?"

"Percy, she just wants to help." I glared at him for the tone he used on Madam Pomfrey. After a brief glaring contest he looked down at the floor and relaxed a bit and let the healer give him the same checkup she did with me. Then she noticed the bandage on his right hand, and I remembered seeing his hand bandaged when I first met him.

"What happened to your hand?" I asked him as the nurse tried to undo the bandage but Percy pulled his hand away from her.

"I got hurt about a month ago. It's not a problem." He answered holding his injured hand.

"Judging by the looks of the wrappings, you've been bandaged yourself up. At least let me check that there is no danger of infection?" Pomfrey held out her hand, and after a few moments Percy reluctantly placed his hand in Madam Pomfrey's palm. When she got the bandage undone and saw what was on his palm she gasped and turned pale. "How are you still alive, Johnathan?" She whispered.

"Someone who knew what to do found me in time." He replied evenly, not looking at her. I glanced at his palm and saw a red welt with spider veins spreading out from it and there was a blackish tint to the welt as well. "Can I please go now?" He wrapped his hand back up.

"Well, Poppy, what do they need?" Professor MaGonagall asked the nurse.

"They should at least have some chocolate."

"Professor Lupin already gave us some." Hermione spoke up.

"He did? Well it looks like we finally have a defense teacher that knows his remedies. Yes you two boys may go, and be careful. It's bad enough having one Potter always ending up in the Hospital wing. I don't want to be seeing two of you in there all the time." With that Madam Pomfrey left.

"Two of us?" I turned to MaGonagall hoping to hear the words that I have been waiting for. She gave me a rare smile before replying.

"Harry, would you be as so kind as to escort your brother back to the Great Hall for his sorting while I talk with Miss Granger about her classes." A smile crept onto my face as I nodded and pulled him out of MaGonagall's office. He pulled his arm from my grasp sharply as soon as the door closed behind us.

"Sorry." I murmured as I recalled what he said about hitting people who touched him. "So, did Professor Snape tell you that we were brothers?" He nodded. "Why didn't you say anything when we met in Diagon Alley?"

"I didn't know if anyone had told you. Plus I didn't know what to say."

"It's ok; I wouldn't have known what to say either. I hope you're in Gryffindor, that way we can spend more time with each other." I told him and he looked at me.

"What if I'm not in Gryffindor?" By this time we were heading down the staircase to the Great Hall.

"Then we'll just have to find time to hang out. Me, Ron, and Hermione could help you get caught up with your classes." He smiled at that.

"You'll have to fight the twins for that job." We entered the Great Hall and I saw that the last of the first years were just finishing up being sorted.

"Good luck." I told him and he gave me a slight smile as he walked up the Hall to be sorted and I made my way to Gryffindor's table and sat down next to Ron.

"Where's Hermione?" My friend asked quietly.

"Talking with MaGonagall about her classes." I whispered back just as Dumbledore stood up at the staff's table.

"Welcome all of you to a new year of school here at Hogwarts. I know you have all heard rumors about a new student joining the third years and they are true. I'm sure all of you will join me in welcoming him to our halls. Might I present Johnathan, Harry Potter's twin brother." There was silence in the Great Hall for a few seconds before there was an uproar amongst the student body. Dumbledore raised his hand and silence reigned again. With a gesture, he motioned my brother forward. Whispers spread across the Hall.

"That's the boy from the train."

"The one with the snake."

"That's Harry's brother?"

The boy in question stepped up and sat on the stool at Professor Flitwick's direction and the Sorting Hat was placed on his head. I tried not to hold my breath as I waited for the Hat to call out which house he'd be in. After a couple of minutes the Hat spoke again and I think it's safe to say that I wasn't the only one who was surprised by what it said.

"Fine! If that's the way you're going to be, then enjoy your time in Slytherin!"
