Okay, sorry for the wait on this chapter. I had it written for a while, but I wasn't sure that I liked it. I didn't know how else to change so it's going up anyways. Sorry for any mistakes, I'm terrible at editing.

Also, Sheldon is two minutes younger than Missy.

I do not own the Big Bang Theory.

ENJOY!


Sheldon had the IQ of 187, so suffice to say Sheldon is smart. Sheldon is really smart, thus allowing him to be able to multitask like no other. He was able to do his physics exam while listening to a German audio tape, he was able to write equations into the air and vacuum his family room. He was able to read comic books while discussing twistor theory with one of his professors.

So yeah, he could do two things at once, and it was something he prided himself about. But the next task at hand looked quite difficult. Sheldon was leaned against the cool wall of the school, there was about five minutes before the bell was going to ring and Penny decided that she needed to make him germy before the school day even begun.

From this position he could see Raj, Howard and Leonard in the parking lot. It was obvious that Leonard was trying not to gape at him and Penny together,

Sheldon knew, that due to evolutionary reasons and pathological insecurity, he also factored in on how mammals were naturally possessive to things that they felt were theirs, he knew all that stuff.

But all he was really thinking about was, 'stop looking at her Leonard, you're not allowed to stare at her.'

Yes, his brain still wasn't fully functioning.

Sheldon took all of his multitasking ability and grabbed Penny's head pulling her towards his mouth. He cut her sentence off, but it wasn't as if he was listening to her anyways. Sheldon usually kept his eyes closed during romantic moments with Penny, but this time he kept his eyes trained on Leonard.

He knew that what he was doing was the equivalent of peeing on Penny's leg, but he didn't stop. He watched gleefully as Leonard's eyes widened, but didn't turn away, Sheldon smiled around Penny's mouth.

He let his hands wander from Penny's hair to the curve of her rear and he squeezed the jean clad flesh beneath his palms. He usually wasn't this crude in public, but he felt that it fit. Penny broke away from his mouth and sucked on his neck, luck seemed to be on his side. Not that he believed in it.

When Penny gave a breathy whimper, Sheldon didn't want to risk losing eye contact with Leonard, so he winked, somewhat menacingly at him before closing his eyes and letting his head hit the wall with a groan.

After a minute or so, Sheldon pulled Penny away from him. "How about you don't give my mother another reason to hit a bible over my head?" he whispered. Penny giggled.

"I think the only problem you have is in your pants."

He gaped at her, and realized that his pants wouldn't hide anything.

"Don't worry, you're a genius, you'll think of something." The way Penny said it, made it clear that he probably wouldn't find a way to fix it.

Some genius he was.

They're lying down on the hood of her car, he's pointing out her star to her. After that they're sort of just lying there.

"I find this act incredibly pointless."

She only shushes him and tells him to just feel. Feel what exactly he doesn't know, and he won't ask because she won't answer. "You're still coming to the party right?" she whispers.

He nods stiffly against her. He doesn't want to, but he's been told by Raj that everyone was attending, that included them. At least then when Penny probably either gets tipsy with Molly or Lucy or whomever she chooses to spend her time with and demands that dancing is a part of social obligation, leaving him alone to wander he'll have someone to speak with.

Even if it is Leonard.

He wants to ask her what they'll do next year when he's in Germany and she's still here. He took the liberty to do the research, and he didn't like what he found. Odds were that they were going to terminate the relationship, due to adultery. While the research shows that it's usually the man that commits the crime, he knows with the utmost certainty that he would never allow another person's tongue in his mouth unless it be Penny's.

He also knows that Penny probably wouldn't cheat, but the numbers are against him.

The question becomes more daunting each passing day, Germany or Austin?

He tells his mother that the plan is still as it always was, he tells his mentor that too, and his professors. Except the plan is not as it always was, because it seems that he is off route and lost the map. For the life of him, he does not know what to do.

He feels that he should ask Penny to make the decision for him, but he's also fairly sure she would just smack him. She's never very good under pressure.

"You'll have fun." She murmurs against his neck.

"You can't possibly know that,"

"Fine, but you can try to have fun."

"I cannot confirm nor deny that."

She laughs, and sighs. Sheldon takes into account that they just lay there for another half an hour or so before getting up and going home. It was a pointless activity, but it was nice. Just nice...

Oh good Lord, Sheldon thinks, the women has reduced me this.

"Mamma has been asking about you." Missy said when he walks through the door. "I told him you were with the boys, you know, I don't think she likes Penny."

"Mother doesn't like anyone that doesn't like Jesus."

"I don't like Jesus." she says perplexed. Sheldon raises an eyebrow at her.

"Oh, oh, hey look at you Shelly makin' jokes."

He chooses not to respond. Sheldon doesn't mind his sister most times, of everyone in his family his sister would be his favourite. But there were still times when she annoys him till no end, right now would be one of them. She grabs his sleeves when he tries to shift his way around her to his room.

"Shelly, hold up!"

"What is it Missy?"

"Nevermind, lets go to your room."

And as if she had some sort of permission, she bounds up into his room and shuts the door. He sighs and slowly climbs up himself and enters his bedroom.

"I want to help you."

He wonders how exactly she can help him. His only problems are his work and Penny. Neither are solvable.

"At the party, you don't want to be making a fool of yourself." He listens and nods to her, too tired to tell her to get out.

It's really starting to weigh on him, that he's going to be leaving, and if he doesn't then he'll grow to resent her. He knows he will. He's got to leave. He's got to leave Penny, and her warmth and her smile and her dandelion coloured hair, and her happiness. He's going to leave her, and she'll forget about him.

And then they won't be Penny and Sheldon. It's just going to be Sheldon. He doesn't remember the last time he felt so lonely and utterly hopeless.

"Shelly, aren't you listening to me?" Missy's voice is set firmly in the background. He won't bother with her, he'll just wallow in his misery.

"Shelly?"

They're trying to spend more time together, because of his impending departure but the more time they spend together the worse it gets. She might not be able to recall every single conversation, every laugh, smile, or bitter scowl and harsh words that they sent to each other, but he can. He can remember it so clearly.

He feels his bed dip with the added weight of his sister.

"Shelly, what's wrong?"

There will be no more just nice evenings with Penny, in defeat, his head lolls onto Missy's shoulder. "I'm leaving." he tells her sadly, "I'm going away,"

"Where?" She shrieks surprised. "You're still going to Germany?"

He nods against her.

She doesn't say anything for a seconds, he can hear her swallow. "But...why?"

"I've got to go. It's my future Missy, it's my life. I can't just halt it because I have romantic relations with a pretty girl."

"But it isn't like that." Missy insists. She nudges his off and then all he sees is her opening and closing her mouth without saying anything. He wonders what's got her so speechless. Missy isn't usually so quiet, so he thinks about some of the stuff he used to do when they were younger.

Missy, despite you know being his polar opposite, he's quite fond of her. Maybe it's because she's his twin and there's some sort of bond that twins hold, but Sheldon mostly thinks it's because Missy doesn't apologize for doing anything. Missy is who she is and she accepts it. She knows that she won't make a mark in the world, but that doesn't matter to her, what matters the most is that she's happy with the person she dies as. If she likes the person that she will become, and the person that she is now.

They're more alike than he would care to admit, because all they do is plan for the future. Sheldon knows that if his sister had is IQ points that she'd probably be a lot further in research than he is right now, because Missy is just like that. She makes the most of what she's got.

"I mean, I thought you'd finally stay. At least for a little while." she sounds so sad it takes Sheldon for surprise. He doesn't respond because he knows that Missy will explain herself. She isn't up for letting anyone guess what she's thinking, she needs to make sure everyone knows.

"You never stay, and it's because you're unhappy here. And I get it, sorta you know, Texas, this goddamned town. It isn't for everyone. You're meant for bigger and better things. But..Shelly!" she whines and grabs his shirt trying to shake him.

She can't, because she's just just as skinny and tall as he is, but she still tries. "You're never home, and between mom goin' crazy, and George being, well you know George, it gets a little scary with Dad."

So that's it. Sheldon never gave a thought about his father's attitude towards his siblings. Bill Cooper loved his first born son, and his little girl. He tolerated his wife, and had a less than stellar opinion over his youngest child.

Boy's too smart for his own good.

He didn't think that his father was scary to anyone but himself. Suddenly there's a 100 ton of guilt that has landed in the pit of his stomach and he looks at his sister, and he looks at the eyes that match his and he is just so sorry.

So so sorry that the only person he's thought of is himself.

"I didn't know-"

"Now Shelly, don't get stupid. You always did when it came to feelings." her eyes can hold emotion that his never could. He was too clinical, too logical. "He's never talked to me the he talks to you, or George, I know he gives you a hard time and you've got every reason to feel the way you do about him. And for leaving, and not wanting to come back. I get it, I do. But I mean, I miss ya. Sometimes him and mom go at it so loud and he's throwing things, and she's muttering words of the lord under her breath and those are the times that I wish it was like before. Where I'd come to your room, and you'd do some cool science thingy to keep my mind out of it. And then I'd fall asleep and I'd feel...you know, like I had a brother."

He knows what she's talking about. The times when he was younger and had to stay at home and go to elementary school. They'd fight, and Missy would worm his way into his bed and ask him to make the noise go away, he was smart enough, he could do it.

He obviously couldn't make the noise go away, but he could distract her long enough that she could go to sleep.

"I thought, with Penny and all, you'd I don't know, stay another year. Or, I don't know, stay."

Missy loves him like a sister loves her brother. And he supposes he loves her too, more than the rest of his family. Because she's the only that accepts him.

So the guilt doesn't go away. He says, "I'm sorry."

She nods, Sheldon learned, that words have a way making things better. Not worse. At least not all the time.

"I'm sorry you think that Penny was what would make me stay. And not you asking me."

"Family don't matter to me. It don't matter that much to you either." Missy responds. It's true, it doesn't. Blood isn't thicker than water.

Call it trust issues.

"You could though. You could have asked me to come home for the holidays. I would have." Sheldon knows when he is saying this that he would have. He knows with absolute certainty, that he would have been home for the two weeks in December. And the weekend in November. And Spring break. And Summer.

But he doesn't like it at home, and he's a lot more selfish that he originally thought he was. So he didn't come. Mostly because she didn't ask.

"Look at us getting gushy. Look, I don't want you to be here, you don't like it. And I certainly ain't gonna make you do anything you don't wanna. I just thought that you would."

He nods again. She isn't looking for an apology.

"So you haven't told Penny yet."

He shakes his head.

"She's probably thinking about it just as much as you. Just talk to her, don't be such a pansy."

So he smiles at that, because she's a little bit right. Because he's thought about this, and there isn't any way, except to talk. Her eyes sparkle like his. The party is forgotten, and Penny is sort of forgotten, and all that remains in the room is a new sense of kinship and a bond that's been repaired.

They're siblings, but they have different families. Hers is filled with a loving, eccentric mother, and loud father, and cocky brother, and absentee twin. His is filled with an overbearing mother, and a hating father, and a brother he's never really known, and a twin that he just likes. And maybe family doesn't really matter to them, but that's okay, because they matter to each other.


I know this chapter like got no where...but I think it's important to know about Sheldon's family, and why he doesn't like it at home. So pretty pretty please, review. :D
