Rating: M (mostly for language I think)

Pairing: Duke/Serenity (although I have no idea what's the name of the pairing... I'd be happy if one of you could tell me!)

Warning: My mothertongue is French, so I don't think my English is perfect even if I've been working hard on it for quite a few years. So please, please, if you see any mistake (especially if it makes a sentence hard to understand!), tell me, and I'll correct it as soon as possible. Thanks! ;)

Two makes three

Chapter 1: SOS

"So, as I just said, to find out the diameter of a... Serenity!"

The math teacher was now staring at the red-haired girl with an unhappy look on her severe face. Serenity snapped back into reality. Her thoughts were as far from the diameter of a circle as they could possibly be.

"Y-yes madam?" she said as she blushed.

"If you're so smart that you don't need to listen, can you give us the formula?"

"I... I don't know, I'm sorry, madam..."

Serenity bobbed down as she felt her cheeks becoming even redder and tears coming up her eyes. The teacher sighed.

"Well pay attention now!"

Serenity nodded, and was saved by the bell that announced the end of the school day. Thanks God, she thought. Serenity quickly stood up and almost ran outside the classroom. In front of her locker, she sighed and leaned her head on the cold metal. I'm so in trouble...

"Had a bad day, honey?"

She felt arms wrapping around her waist and lips softly kissing her cheek. She quickly made her tears disappear from her eyes with the back of her hand and turned to smile at Duke.

"Well it surely was a long one!"

"Mine was long too... I missed you."

He kissed her passionately.

"Hey, mate!" Joey's voice suddenly said. "When I said I was totally cool with you dating my little sister, I never meant I was 'totally cool' with you making out with her in front of everybody! Especially in front of me."

"Give them a break, Joey, they're so cute", Tea replied.

Tristan said nothing. Serenity saw that he was staring at the floor, doing everything he possibly could to avoid looking at them. She knew that she'd broken his heart six month ago, when she chose Duke, and she didn't want to make him suffer more, so she turned away and opened her locker to take some books.

"Yeah, whatever you say, Tea. She's my sister and no one's gonna kiss her like that when I'm around."

Serenity slightly smiled as she closed her locker. Joey had always been so protective towards her.

"You know, big brother, one day you'll have to admit that I'm growing up. I'm fifteen now you know."

"Serenity, it doesn't matter if you're fifteen of fifty, you'll always be my little sister. Now, come on! Who else wants to eat something? I'm really hungry!"

"Dude, you're always hungry", Tristan said.

However, everyone agreed with Joey that a meal would be a good idea.

"Just let me take my books and I'll be right back", Yugi said as he headed straight to his locker.

"Man", Joey said as he leaned on Serenity's locker. "I can't wait for this week to be over. What are they trying to do here, kill us? I've got like tons of stuff to do already and it's not even the exams time! What are they thinking?"

"That's called homework, Joey. You know, those futile things you usually don't bother doing", Tea replied.

Everybody laughed except Joey.

"What do you mean?! My homework's always done in time!"

"Yes, because Tea is kind enough to do it for you", Duke said as he rolled his eyes.

"Ok, I'm ready!" Yugi said with his most cheerful tone.

"Wanna know what I'd like to eat? A good cheeseburger!"

"Don't tell me", Tea commented. "Is that all you can eat?"

"Nope! But it tastes good!"

He opened the door for his friends. On their way to the fast food, they everybody was speaking, telling how long and terrible this day had been... everybody but Serenity, who remained silent.

"Something's wrong, honey?" Duke asked when he noticed her weird attitude.

"Uh? No, I'm fine, don't worry... I guess I'm just tired."

She gave him the biggest smile she could as they all entered the fast food. Joey almost ran to the counter so he could order first. Serenity looked at the menu, wondering what she should take.

"What do you want?" Duke asked. "I'll pay for you."

"Uh? Oh, thanks, that's nice! But I'm not really hungry right now... I think a milkshake will be just fine."

"You sure? I don't want Joey think that I'm not letting you eat!"

She laughed.

"No, really, I'm not hungry. I'm feeling a bit nauseous today."

"You're sick?"

"No, I don't think so... you know, just tired."

"All right then..."

After getting their orders, they all sat around a table. Serenity was quietly drinking her chocolate milkshake when they were all eating.

"Sis, are you ok?" Joey asked.

"Yes, Joey, I'm fine", she said with a smile. "Hey, Tea! What about we go shopping together after this?"

Tea looked at Serenity. When she saw her eyes, she understood that Serenity didn't want to shop at all. She just wanted to be alone with her.

"Yes, of course!" she said with a cheerful tone.

Serenity smiled and looked a bit happier. She got into her friends' conversation.

"That math teacher scares me! She looks so mean! I wasn't really paying attention for one minute and she was so rude!"

"Yeah, I remember that one, she was such a bitch", Joey said.

"Joey!"

"What? Tea, don't tell me that you liked her!"

"Of course not, but I still respect her as a teacher!"

"Yeah, well I don't. I can't remember how many hours of detention I had because of her..."

He immediately stopped his sentence and pointed his sister:

"And I'm telling you, young lady: don't you dare walk into my footsteps. I don't want my sister in detention every week."

Tristan laughed.

"I don't think that could possibly happen. Even Tea is more likely to have detention than Serenity."

The conversation continued. After half an hour, Tea and Serenity stood up.

"Boys, we'll leave you alone, if you think you can survive without us!" Tea said with a teasing voice.

Serenity laughed and gave Duke a kiss on the cheek.

"I love you", he whispered to her hear.

She smiled and blushed.

"I love you too", she whispered back. "Have fun!" she said to the others.

Tea and Serenity left.

"So, Serenity, what did you want to do?" Tea asked. "I was under the impression you didn't really want to shop..."

"Uh, you're right. Can we go somewhere else? Somewhere we can be alone? I'd like to talk to you..."

"Come home with me, my parents won't be back before hours."

Serenity nodded in silence. Tea looked at her in silence, wondering what could be wrong. Serenity looked quite lost and sad. The only reason she could think of would involve problems with Duke, but their relationship seemed perfect. It couldn't be troubles with Joey: she was so happy that her mother let her live with Joey and their dad, so she could always be close to her boyfriend, brother and friends...

"Here we go", Tea said as she opened the door of her house.

She dropped her bag on the floor.

"Here, have a seat... did you want something to drink? To eat?"

"N-no, thanks, Tea, I..."

Her voice sounded like she was on the verge of tears as she sat on Tea's couch. Tea frowned, not understanding what could be wrong.

"I... I have something that I must tell and you're the only one I can... oh, God..."

Serenity deeply breathed in. Her lips were shaking, but when Tea put her hand on her shoulder, she finally found the courage to say, with a very soft voice:

"I am... uh... pregnant..."

End: Yeah, I wanted to make a preggie fic, I almost did it in "A public matter" but finally I thought naahh… not a good idea! Please review ^^
