HellRat: You people better like this! The main romance is Harry x Hermione however it will be a little more about the OC. The main romance for the OC is a surprise and who every figures it out first (Though it shouldn't be hard) gets a surprise! By the way the preface sucks!

Harry: Umm... HellRat does not own Harry Potter.

Hermione : If she did it would be interesting to say the least.

HellRat: I worked hard on the idea! Oh and this story is based off the movies and books kind of mixed together because I don't know that much about the books... sorry. And they look like they do in the movies. And sorry for spelling and grammar mistakes. Ok Draco you do the enures!

Draco: No.

HellRat: Please!!!

Draco: Hell No!

Kalen: Do it or I will smash your face in! (Holds up fist)

Draco: Ok, ok. (Puts hands up in defense.) On with the chapter.

Kalen: (Grins) Now was that so hard?

Draco: Yes.

Kalen: (Attacks Draco)

Preface

Ten years ago

Dumbledore picked up the two crying babies and stared at there faces. He looked at the boy, seeing his future. He sighed when he saw the truth. "Your destiny will start out different but in the end become one. I wish I did not have to take you apart." Then Hagrid walked over to him.

"What should we do mister Dumbledore?" He asked as he gazed at the babies. The old man gave the boy to Hagrid.

"They will be separated. They will be safer apart. The boy will go to his aunt and uncle." He explained and started walking away with a now sleeping baby girl.

"And the girl?" Dumbledore stopped at the other man's words.

"I will take her. Her destiny is to be raised in the magical world. His is not." With that he was gone. When he was gone, Harry woke up and cried. Little did Hagrid know that with Dumbledore the girl had woken up as well with tears. They cried to be together again.

Present time

Harry stared out the window of the train as Ron talked nonstop. It would be his first year at Hogwarts and he had already made his first friend. He sighed as he looked back at Ron who was now staring at him. "I have a question." Ron said.

"Yeah?"

"Where's your sister?" Harry's eyes widened and confusion was firm on his face.

"I don't have one." Came his response. Now Ron was confused.

"Are you sure. The stories about you mentioned a twin sister who had survived." Ron shrugged thinking it was probably just a lie.

"Well, I did have a sister but my aunt and uncle said she died with my parents." Harry looked back out the window wondering why he still believes that after everything that happened.

"Hey Harry would you like to see a spell to turn Scabbards yellow?" Ron asked when he saw the expression Harry had. The brunet nodded with curiosity. Ron pulled out his wand and cleared his throat but before he could perform the spell the door slid open and two girls walked in.

"Excuse me have either of you seen a toad. A boy named Neville lost one." Said the girl with light brown hair.

"No." the red head said.

"Oh are you doing magic. Let's see then." She said. Ron cleared his throat again and whispered the wards as he pointed the wand at the rat. Nothing happened. Ron shrugged and went back to eating the food he had.

"You call that magic?" Spoke the other girl which neither of the boys had seen the face of until the shorter and lighter brunet moved out of the way. The boy's faces turned to shock at the girls face. She looked exactly like Harry except for small thing. Her hair was the same color but went down to her waist, her eyes were the same green but no glasses, and more feminine features. She was more on the beautiful side while Harry was more on the handsome side. "It's not very good is it?" Her attention was on Ron and she had not noticed Harry yet until the other girl gasped. The taller looked at her with question as the other pointed at Harry.

"Kalen you didn't say anything about having a brother." The girl now known as Kalen looked at Harry and her beautiful green eyes showed surprise. She examined him and her eyes landed on his scar. Harry did the same and his eyes landed on a scar in the same shape as his on her neck.

"Harry James Potter?" The name left her lips and the other girl showed even more surprise. Harry nodded. Kalen smirked and walked over to him. She pointed at the girl behind her. "That's Hermione." She reached out a hand. "I'm Kalen Marie Potter. Nice to finally meet you." He stared at her hand before taking it and smiled. 'Speak of the devil.' He thought.
