AN: This is my first Harry Potter fanfic, so reviews are accepted. Flamers will be replied with a sharp retort if I so deem it needs one, or ignored. So, please don't post them. Thank you. Please Enjoy. P.S: This takes place during the summer between fifth and sixth year, though may or may not go along with the book. Currently still in my head.

Hermione sat on the car's seat, lying flat on her back and staring up at the luggage rack above her as the train rolled on the tracks, swaying her back and forth. Harry and Ron had gone of to find some other students to play Wizard Chess, leaving her in peace. She was secretly glad that school was over for the summer. She felt this every year, though she would never admit it. She had to keep her bookworm reputation in tact for the Gryffindors. But, as to the reason of her glad it was summer; that reason had opened the door to the car.

She looked at the person upside down and smiled. He was tall, had nicely combed black hair, dark blue eyes, a straight nose, strong chin, chiseled features, and a smile that made her heart beat quickly. But not in the way of romantic love. Hermione raised herself up a bit and the young man sat down where her head was. She laid back down, resting her head on his lap, and smiled. "I've missed you, Anteros," she said.

He smiled down at her and ruffled her hair gently, but not messing it up too badly. "We saw each other every day," he said.

Hermione rolled her eyes. "Yeah, but it's kind of hard to have a friendly twin talk when you're in Slytherin and I'm in Gryffindor. What would the houses think if we were nice to each other?"

Anteros chuckled and said, "That we'd gone completely bonkers."

Hermione smiled. She loved her twin brother more than she did Harry and Ron. Anteros was her other half and they shared everything. Unfortunately, since she had been sorted into Gryffindor and he into Slytherin in their first years, they'd had to pretend to hate each other. No one knew that she had a twin, except for Harry and Ron, of course.

Anteros, though, was the reason she loved the end of school. At home, they didn't have to worry about putting up fronts. Their parents were usually away from the house, so, for the next three months, it would be just them. They would chill out, hang with friends, get into mischief, and spend as much time together as they could stand. Until, of course, she had to go to the Burrow to go shopping with the Weasleys. Then she wouldn't be able to talk to him until next summer unless they planned a secret meeting or something.

She felt a tap on her forehead and looked up at her twin. "I know that look, Mione," he said, still smiling. "You're worried about our quality time."

She laughed. "You know me so well," she said.

"True," he replied. "But don't worry. We have all summer to have fun...except..."

Hermione narrowed her eyes. She'd heard this tone before. He had bad news. Well, bad news for her. His tone said that it was good for him, in a way. It had that slight guilty sound to it, as if sorry to ruin her plans.

"What's wrong?" she asked.

Anteros blinked and said, "Well, I invited someone to stay with us for the summer. Now, before you get angry," he said quickly, "he's promised to be on his best behavior. I only told him that I had a sister. I asked him to come with us because I thought it might be good of him to get away from his family for a while. Troubles, you know."

Hermione sat up slowly and said, "You could have asked my input. Seriously, even an Owl over breakfast would have been nice."

He sighed. "I didn't tell you, because I thought you were going to trust me. I understand how much crap we'd get if people figured out we were twins, but I trust this guy to not to tell." He met her gaze and she stared into his blue orbs. They looked nothing alike, but couldn't be closer if they were Siamese twins.

She groaned softly in defeat and raised her hands up as if surrendering. "I give, Ant," she said, using her pet name for him, though it was ironic. She sighed and said, "I'll be nice. I won't hassle anyone or anything. I'll trust you."

Anteros tapped his heart. "Twin Promise," he said. They'd come up with it when they were 8 and had decided that pinky promises and crossing your heart weren't good enough. Their connection was stronger than any of those children promises.

Hermione placed her hand over his heart and he placed his over hers. "I, Hermione Granger, promise on our connection, to not be mean to your guest. I will behave and be nice to him...unless he really really pisses me off." she added the last.

Anteros laughed and said, "I, Anteros Fletcher, accept your promise." He leaned forward and hugged her. "Thanks, Mione. This means a lot to me," he said.

Hermione returned her brother's hug and said, "I know."

She did. While she was free to go to the Burrow and visit the Weasley clan, Anteros had no one in the wizarding community to go to for company when she was away. He was stuck in their neighborhood with the Muggles. Though they were dear friends, they weren't anyone he could talk to about Quidditch or anything magical. If having his friend over made him happy, she would play nice. Even if the person was undoubtably Slytherin.

The train started to slow, signaling Anteros' cue to leave. He had to return to his House's car and gather his things. He stood up and squeezed her hand. "Will you make cookies like you usually do?" he asked.

She rolled her eyes. "Duh. It's our tradition. Stay up late on our first night back and gossip about the Houses while munching on cookies." She gently kicked his heal with her shoe. "Go. You have to get ready to ignore or belittle me on the platform." Anteros laughed and left, closing the door of the compartment.

Once he was gone, Hermione let her smile fade. They wouldn't have any Twin time. She just knew it. Anteros' friend would take his attention, leaving her behind. Their small traditions, like the one tonight, would be lost this year. She mentally slapped herself. She was being selfish. If Anteros wanted something that made him happy, she would be a big girl and deal with it.

Confident in the resolve, she put her smile back on and pulled on her jacket. It was red with gold trim on the outside, but the inside lining was dark green with silver thread. She wasn't too thrilled about it, but didn't bother changing it. It looked nice and could be reversed for when she mocked Slytherin. Plus, the lining kept her warm enough on the windy train platforms.

Ron and Harry came back in, their pockets jingling from their winnings. They had started betting on the games a while back, claiming it made them more interesting. Yeah, right. It relieved their fellow students of a couple of coins and it filled Ron and Harry's pockets.

Harry smiled at her. "You look happy," he said. "Was Anteros here?"

"Just missed him," Hermione said, taking her trunk down from the luggage rack.

Ron snorted. "I still can't believe your twin got sent to Slytherin," he grumbled.

Hermione fought hard not to roll her eyes at that statement. He'd been repeating it forever. "Honestly, Ron," she said. "It's been almost six years. Have you still not gotten over that?"

He turned to her, pushing his red hair out of his eyes. "It's hard to think that there are two of you, Hermione. But it's a male version and he looks nothing like you."

She smiled to herself. "Of course not, Ron," she said, opening the door. "I'm a girl and much prettier." She left him there with his mouth open, trying to come up with a comeback.

The train corridor was crowded with students trying to get out onto the platform. Hermione was shoved from the side and fell against someone. "Sorry," she said, placing a hand on the wall and pushing herself upright. She looked up to see who she'd run into and froze.

"I'm flattered, Granger," Malfoy said, smirking like he usually did. Hermione pushed herself away from him, but she was shoved again and landed against Malfoy. Hard. The force had them landing in a pile on the floor.

Hermione opened her eyes and found Malfoy above her. That damn smirk still on his face. "I'm starting to think you like me, Granger. Too bad I don't go for Mudbloods."

She shoved him off her, grabbed her trunk, and turned. She followed the crowd onto the platform and found a pillar to lean against as she felt the big bump on the back of her head. It was tender and she hissed in pain as her fingers touched it. She must have hit it on her trunk when she fell. Now, all she had to do was wait for the platform to thin out to nothing and then she, Anteros, and their guest could go home.

She spent her time talking to Ginny as she waited for her brothers to get off the train. Ron still hadn't come up with a comeback, but he gave her a 'happy summer' and a promise to see her when they needed to shop for their school supplies. Hermione waved the Weasleys and Harry off, feeling slightly lonely.

There was a hard cough and Hermione looked to find Anteros with his trunk. She smiled slightly, then said, "Where's your friend? Mom and Dad won't like it if we're late meeting them."

Anteros chuckled. "I'm so glad you're the uptight twin," he said.

She blushed. "I'm not uptight," she protested, though she knew that he was right. She was the uptight one in any grouping. Harry and Ron, she was the one to keep them focused. With her and Anteros, she planned and he made sure she had fun along the way. She shook herself out of those depressing thoughts.

"Oh," she said. "I forgot to ask. Who's your friend?"

"I didn't know you were friendly with Anteros, Granger."

Hermione didn't take her eyes off of her twin as she heard the voice. Anteros didn't even look sorry. Slowly, Hermione looked past Anteros and glared at Malfoy. "What's he doing here?" she said.

"What's Granger doing here?" Malfoy asked, his eyebrow raising high on his forehead.

Hermione felt her hand itch to slap the demeaning look on his face, but stilled her hand. She reminded herself of her promise. Thankfully, Anteros saved her from saying anything. He put a comforting arm around Hermione's shoudlers.

"Malfoy," he said, smiling. "I'd like you to meet Hermione Granger, my twin sister. Mione, I'd like you to meet our guest for the summer."

Yay! You've made it to the end of the first chapter. Now, see the blue words under this note? Yeah, take your mouse and click it. Review, okay? It would make me happy and a happy Sensula makes...well, you'll just have to see. Thanks for reading.
