What if Lilly Potter had twins who were separated at birth? Arabella Potter has always thought her name was Arabella Black... what will happen when she finds out the truth of her twin Harry Potter?

DISCLAIMER!!! I do not own Harry Potter!! It is owned by JK Rowling. Also some ideas from other FanFictions.


Arabella Lilly Black woke up, she had been having the same dream as she had every night a flash of green light and a baby crying but it wasn't her crying.. she was at least sure of that. Arabella had long red hair, her eyes were hazel and she had freckles on her nose, she also had a birth mark in the shape she of a heart on the back of her neck. She left her room and walked down stairs to find her father Sirius Black sitting at the table, he owned a small shop in Hogsmeade but since it was Saturday he wasnt working. Her mother worked at Hogwarts she taught Astronomy and had left to check on Hogwarts and get ready for school with the rest of the teachers, her name was Adria Black. She sat down and her dad said, "Morning Bella! Did you have the dream again?" Arabella nodded she told her dad about the dream the first time she got it, he always seemed nervous when she talked about as if he was hiding something. But what could he be hiding? It was the day before Arabella 11th birthday, her birthday was on the last day of July so Arabella could not wait. She was a witch well a witch in training, on September 1st (two days from now) she would get to go to Hogwarts School of Witchcraft and Wizardry so she could become a real witch. At that moment the house elf Kreacher walked in, with breakfast. After Arabella and Sirius ate breakfast Her dad said, "Have you finished your Herbology work" "No," Arabella admitted, she just didn't want to work on school before she could even have a wand, but her dad had promised they would go to Diagon Alley on her Birthday to get her school supplies.

Arabella woke up on her 11th birthday. For a moment she forgot it was her birthday because she was having the dream again but she quickly remembered and ran out of her room. Later that afternoon they were in Diagon Alley, first they walked into Madam Malkins robes, then they went to Flourish and Blotts, then for their last stop they went to Olivanders to get her wand. While walking their they saw Harry Potter who although Arabella was very exited about and dad couldn't stop staring at mom pulled them away. When they got into the wand shop Ollivander said "Welcome, what is your name?" My name is Arabella Black" She replied, Olivander pulled out wand after wand and everyone Arabella tried she just blew something up. Finally after 2 hours of blowing stuff up Olivander pulled out a wand, she tried it out and sparks flew around. "Curious." Said Olivander "What's curious?" My mother asked,"Well I'm assuming you all have heard of Harry Potter?" We all nodded "He was just in here, he bought a wand with Holly and Phoenix feather, and the tree from which the holly was from is also where the wood in this young lady's wand comes from," my mother and father looked absolutely terrified they quickly paid then left the shop as fast as they could.

They were on platform 9 and 3/4 Arabella couldn't believe it! She got on the Hogwarts express and was waving goodbye at her parents from the train. Of course they lived in Hogesmead and their house was practically on the school ground but they insisted that Arabella ride the train. The train started to pull away when none other then Harry Potter walked in. I couldn't believe it, Hi I'm Arabella Black, but everyone calls me Bella. I said, Im Harry Potter. he responded, then another boy walked in, Hey, the boy said, I'm Ron Weasley we spent the whole train ride talking, Ron asked Harry to show him his scar so many times. When they got their a large man named Hagrid took the In boats across the lake, when they arrived at the castle Professor Mcgonagall told them to wait in the hall, then finally she came back. She led all the first years to the front of the great hall then they started having kids come up to the front put on a hat and the hat yelled their house. Abbot, Hannah- Hufflepuf! What house do you want to be in? Ron whispered, I want to be in Gryffindor, that's where my parents were. Cool Ron said, my whole family has been in Gryffindor. Where do you want to be Harry? I asked, I don't know he said I've never heard of the houses before. You don't want to be in Slytherin Ron said, not a single dark witch or wizard wasnt from slytherin. Oh said Harry, Black, Arabella! I was called up slowly and very nervously I walked up the steps and put the hat on, Hmmm interesting loyal for sure, you would be good in Hufflepuff oh but so much bravery, well then GRYFFINDOR!!!! All the Gryffindors cheered, then Like 10 minutes later Granger, Hermionie- GRYFFINDOR!!! I clapped with the rest of Gryffindor then like 10 minutes after that Potter, Harry! There was a lot of whispering and muttering, Harry Potter? THE Harry Potter? The boy who lived? The one who defeated You-Know-Who? Harry walked up to the hat, he looked very nervous and I felt bad for him, after all he didn't seem to want to be famous he just kind of was. A few moments later the hat called Weasley, Ronald, Ron walked up to the hat he looked like he was about to be sick, not even a second after the hat touched is head it yelled GRYFFINDOR!!! Ron looked so relived and he came over to sit by Harry, Hermionie, and me.
