"Proof"

Amara's POV

Okay, deep breath, Amara. I was on the train to Hogwarts School of Witchcraft and Wizardry, where I would learn magic for the next seven years, standing outside the compartment where I was sure my brother, Harry Potter, was sitting. There was a red-haired boy sitting with him that I didn't recognize. Neither of them had noticed me yet. I took another deep breath, secured my hand around my trunk handle and walked into the compartment.

Harry's POV

Ron was telling me about his wizard card collection when the door to the carriage opened and a girl walked in.

She was about my height and had waist length black hair with bangs that reached the tops of her eyes. Any longer and she wouldn't be able to see. Her skin was tanned from being outside and she looked almost like a cat. Her eyes were almond- shaped and green, just like mine. She was wearing a light blue and pink tank top and a pair of blue jeans. Around her waist was a belt with what looked like diamonds in it. From the belt hung her wand and a pure white—something, with a black symbol etched into it. She appeared to be really excited about something. My mind registered her appearance and came up with the perfect summary; wow.

"Um, I was wondering if I could sit with you guys?" Her voice was like bells, high pitched and beautiful. She seemed nervous, like maybe we would turn her down, like that was even possible.

"Erm… Sure." I replied. Ron seemed to be at a loss for words. He threw me a who-is-she-and-why-does-she-want-to-sit-with-us look.

She smiled and proceeded to lift her trunk, which was as big as, if not bigger than mine, with seemingly no effort onto the luggage rack above our heads and sat down facing me. We just sat there looking at each other for a minute. It was very awkward so I decided to break the silence.

"What's your name?"

"I'd like to hear yours first, if you don't mind." Weird, but okay.

"I'm Harry, Harry Potter."

"Perfect! I knew it was you!"

"I'm pretty sure Harry doesn't want to sign autographs." Ron interjected. He was right. I was sort of over the whole famous thing.

She laughed. "I don't want an autograph. I'm Amara. Amara Potter. I wanted to meet my brother."

I knew I already liked Harry; he seemed nice. He still looked like the toddler in my photograph. He was really skinny and was wearing clothes that were way too big for him and I wondered what had caused him to look like he just came off the street. He seemed skeptical of my announcement, so I clarified.

"Well, half-brother really. Lilly Potter was my mom." Then I realized Harry wasn't paying attention. He was looking at me as if I couldn't possibly exist. There was a red- haired boy in the compartment with us. His clothes were clearly hand-me-downs as well, though he seemed used to it. He had freckles splashed across his face and he seemed to be thinking hard about something. I had to ask him something first.

"What's your name?"

"Ron Weasley." But he was not to be distracted. "Hang on," he started, "How do we know you're not lying to us?"

I knew this was going to happen, and I already had a plan of action. Harry had to believe we were related, so I started with the most obvious thing.

"First, because Airbenders don't lie." They both looked at me like I was speaking a foreign language. Oh, they probably don't know about the Airbenders. I'll explain later.

"Second, I remember how our parents died and I can show you." Harry looked horrified at the very thought, so I moved on.

"Okay, how about this; Harry and I both have green eyes. Exactly the same." Ron started looking back and forth between Harry and me to see if I was right.

"Fine, I'll give you that, but there must be loads of people with those eyes," he said. "I still don't believe you." I felt like I was on trial, or something. I hadn't wanted to do this, but now I didn't see any other way. I hoped that this would be enough proof for them to believe me. I slowly pulled the locket from under my shirt, and held it out to Harry.

"Here," I sighed, "Look inside."

Harry took the locket silently and opened it. His eyes widened. I knew he would see his father, the man who looked exactly like him; his mother, whose eyes he had; the little boy Harry had to know as himself; and the little girl who was unmistakably me. I knew he would see the picture, all the people smiling and waving, but what would he think?

"Who is this?" Ron asked, pointing at the picture across from the family photo. I saw my hand-drawn picture of a man with white skin and hair. He had a clean-shaven, kind face that had wrinkles around the eyes from smiling so much. The man was wearing an orange and yellow robe and had a ball made of air in his hands. I smiled.

"That's my Airbending teacher, Master Katori." I had decided to add a picture of Eragon and Saphira, but I wasn't sure if it would fit. Maybe if I started an album, then I could add pictures of everyone who mattered in my life. My musings were interrupted by Harry finally speaking.

"How is this possible? My whole family was killed by Voldemort." That must be the wizard's name, the one who killed my mom. Ron winced at the name, but I could tell he wanted to know how I had survived.

I started with the story about the moon, explaining how I was reincarnated after the war. I told them everything about the Airbenders, showing them the tattoos on my arms, signifying that I was an Airbending maser. I explained to them what Master Katori had told me about my heritage and how that revelation had lead to my training in Ellesméra. Harry and Ron were hanging on my every word and Ron had lots of questions, especially about the fighting tactics I had learned. I pulled out my sword, Vindr, to demonstrate and Ron wanted to hold it, so I showed him a simple thrust and block.

I also demonstrated some of the simple magic I had learned, making sure they knew the difference between this magic and the magic we would be learning at Hogwarts. Ron wanted to know why I didn't need a wand to use this magic and I tried to explain as best I could, but I wasn't very successful.

Harry was quiet the entire time, he didn't say a word. I panicked. What if he didn't like me? What if Harry didn't want a sister? What would I do then?

When I finished talking, I looked to Harry for approval. He opened his mouth, but hesitated, searching for the right words. I hadn't told them, I could read their minds and I was desperately examining his thoughts, but I couldn't find anything coherent. After an excruciatingly long pause, Harry spoke.

This isn't possible. My family is dead. There has to be some other explanation. Even though I really wanted to believe Amara, she hadn't given me any reason to think that we shared a mother.

"You still haven't told us how that makes you my sister," I said.

Amara proceeded to explain how her mom on the moon was reincarnated into my mom on earth. She told us about Lily finding Amara in the alternate dimension she was sent to and taking her away form the monks to live with our family. Then she began reliving the memory of their deaths. I didn't really want to hear the story, but once she started, I couldn't help but listen to every word.

"You and I were in the crib, Harry. There was another green light and an explosion. That's how I got this." There were silent tears streaming down Amara's face, but she had kept her voice from shaking the entire time. She slowly raised her hand to her forehead and lifted her bangs. There was a tattoo of an arrow in the middle that matched the ones on her hands, but that's not what caught my attention. On the left side of her forehead, there was a lightning- bolt shaped scar, identical to mine. I heard Ron's mouth fall open.

It was true, then. I did have a sister.

Amara let her bangs drop, and then folded her hands on her lap, once again waiting for my reaction. What was I supposed to think; 'I'm so happy to have a sister' or 'How come they told you and not me?'

I got up and sat next to Amara, hugging her like she had hugged me in the picture. She seemed relieved and hugged me back, keeping herself from crushing me in her happiness, and I realized the embrace was familiar. The smell of her, the feel of her, it was familiar. I smiled and I knew one thing for certain; I was glad not to be alone anymore.
