This is a complete re-write of my original Big Bang Theory story, 'The Love Concept.' It's basically the same story, but with a few facts changed, and it will also be better paced and also better written.

"Yes Sheldon. A roommate. I just can't afford to live in that apartment by myself anymore." Penny explained over Chinese food that Friday night, vintage game night.

"Then move." Sheldon said flatly. Everyone in the room gave him a look, Penny was by now too used to Sheldon being insulting to actually be insulted by it.

"Thanks for the affection Sheldon, but no. I like that apartment and I like being across from you and Leonard." She explained. Leonard looked up with a surprised smile.

"Really?" He asked.

"Yeah." She smiled back, making Leonard's chest flutter a little.

"Hey, you must be Victoria." Penny held out her hand to woman in front of her, taking her pale hand in her tan one.

"Hello, it was Penny wasn't it?" She asked. Penny nodded. Victoria smiled, walking into the apartment as Penny led her in. "Call me Vicky, by the way, everyone does."

"Will do. Please sit down." Penny was being more formal than usual, she'd already met around fifteen or so applicants and all had either been annoying, boring or too loud for Sheldon to possibly be able to put up with.

This girl seemed nice enough, talked without going on, asked questions, made Penny laugh. The only thing bad Penny could possibly think about her was that Howard would have to be put on a leash.

Anyone would say she was very pretty, startlingly pretty even. She had that kind of Christina Hendricks- like full figure that made women green with envy, pale clear skin and grey-blue stormy eyes which shone from behind her thick rimmed spiceberry glasses. Her hair reached down to the middle of her back, it was blonde, but with a slightly ginger tinge to it.

"Oh I never asked you, what do you do for a living?" Penny asked, she'd made them both coffee now, and sat much more relaxed on the sofa as she sipped her hot drink.

"Oh..." Victoria swallowed he drink, obviously just realizing she hadn't mentioned it before. "Technically I'm an astrophysicist, but I work a lot more in engineering, I find it so much more fun than staring at whiteboards and rearranging nanoparticles in my head." She chuckled, before sipping her drink.

Penny's eyes were slightly wide for a second.

"You're perfect!" She finally exclaimed, making Victoria jump slightly and look at her with a confused expression.

"Sorry…" Penny said, noticing her outburst. "It's just my friends across the hall are physicists too, this is so weird." She smiled widely at Victoria, who smiled back.

"Axiomatically it's very probable… Given the fact the Caltech University is situated in Pasadena and this apartment building's proximity to the institution. " Victoria pointed out. Penny looked are her oddly for a moment before smiling again.

"Yeah, you're gonna fit right in here."

Penny had to work that Saturday, so Victoria was left in to move all her stuff in alone, and Victoria had a lot of stuff. The elevator was out of order, much to her dismay, so she was forced to struggle with her box full of PlayStation 3 games up four flights of stairs.

Once they were placed inside, she breathlessly made her way back down to the lobby, and groaned at the sight of how many more boxes were left to take up. 'Heaviest stuff first, Victoria.'

She next went to my first box of hardbacks and struggled back up to the apartment, before letting the box drop before the couch, cursing. She put her hands on he bare knees and bent over, trying to regain her breath.

"Well hello there…" She turned round quickly, slightly startled, met with the sight of a rather short young man with shaggy brown hair and red skinny jeans, standing beside another man, who again looked around Victoria's age and wore thick rimmed glasses.

"Oh hi there." She politely smiled, walking over and holding out her hand. They were rather surprised she was taking any notice of them, never mind being nice. "Do you live in the building?" She asked them both.

"I do, right across the hall actually." Leonard said, shaking the hand of the gorgeous bespectacled girl he supposed was Penny's new roommate. "I'm Leonard Hofstadter. This is-"

"Howard Wolowitz, it's a pleasure to meet you m'lady." Howard promptly took her hand and kissed Victoria's knuckles, making Leonard roll his eyes.

Victoria chuckled to herself at Howard's attempt at flirting.

"Nice to meet you both. I'm Victoria Moore. Call me Vicky, everyone does."

"So, how long have you been in Pasadena?" Leonard asked, trying to make conversation and put an abrupt halt to Howard's flirting.

"Just a few weeks actually, I used to live in New York until I got offered a job at Caltech, I've been staying in a god awful hotel until I could find an apartment." She told them. Leonard and Howard were both surprised.

"Caltech? What do you do?" Leonard asked.

"I'm an astrophysicist, although I do find engineering fascinating and I have rather a knack for it." She winked.

Howard had to refrain from getting down on one knee and proposing to her right there, Leonard was also in awe of the woman. "Penny tells me you and you're roommate are physicists too." She said to Leonard.

"Yep, Howard's an engineer, and our friend Raj is an astrophysicist like you, my roommate Sheldon is in the same field as me, theoretical physics, although I'm experimental."

"Cool, I think Sheldon and I'll get along rather nicely." Victoria smiled brightly. Howard and Leonard gave her sideways looks.

"Don't bet on it…" Howard mumbled. Victoria decided to ignore this statement.

"Well, I have some heavy lifting to do. It was nice meeting you." She said, before making her way to the stairs.

"Wait, wait." Howard called. "Allow us to lend a hand…" He smiled in what he obviously thought was charmingly. Victoria wasn't about to pass up help.

"That would be awesome." She gratefully accepted, and the trio made their ways downstairs to the boxes. Howard picked one up, arms shaking from effort.

"What the hell's in here?" He asked, setting it down to the ground for a second. Victoria blushed slightly.

"My PS3 and my Xbox 360..." She said, looking embarrassedly at the ceiling. Howard cast Leonard a joyful look.

"Why do you have both?" Leonard inquired, picking up a box of shoes.

"Well, I think that the PS3's superior in every other way, but I love me a bit 'o Halo." She grinned, picking up a box of clothes. "Shall we?" She made her way upstairs and Leonard caught Howard sneaking a glance at her denim- clad backside. He rolled his eyes at his friend again.

"Thank you so, so much. I can't thank you enough." Victoria said genuinely, after the last box was in the apartment, hugging Leonard. "I'm buying you both dinner tonight." She hugged Howard who looked as if he could die happy in that moment.

"Sounds great. We can eat in our apartment, Penny usually comes over for dinner." Leonard smiled.

"Awesome, what time do you feel like eating?" She asked, unlacing her boots.

"Well it's Saturday, Saturday's Thai food night, we eat Thai food at six…" Leonard said, making Victoria arch her brow. Leonard noticed her trepidation.

"You'll understand when you meet Sheldon…" He explained.

... … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … …

I spent the rest of the day unpacking, Penny came home from her lunchtime shift at four and once we finished finally finished unpacking, she was helping me make my bed.

"Thanks so much again for letting me be your roommate. This apartment rocks." I grinned as I put the pillowcase round my pillow.

"I just couldn't afford to live in it by myself anymore, and I had this room free so I thought 'why not?'" She realized she'd put a pillowcase on inside out, groaned and took it off again, making me chuckle.

"So, what was wrong with the other applicants?"

"How did you know there was anything wrong with them?" She asked, looking at me with a raised eyebrow.

"Your look of relief when you saw a normal female in your doorway." I laughed, she did too.

"You got me there. But when I noticed how smart you are that really sealed the deal. It's kind of important I live with someone Sheldon can put up with."

"Yeah, I've heard a lot about this Sheldon. Sounds like kind of a pain."

"He is, but I think that deep down… Very, very, very deep down, he's kind of a sweetie-pie." She said, plopping the last pillow on the bed. I laughed.

"I look forward to meeting him."

... … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … …

I walked into Leonard's apartment with armfuls of paper bags containing our Thai food. I dropped the bags down on the coffee table before straightening up.

"Wow, you have a great apartment Leonard." I smiled looking round, eyeing the whiteboards covered in equations at either end of the room, and the various models and figures on the book covered shelves. Something across the room particularly caught my eye.

"Oh my… GOD!" I squealed and ran the length of the room to the kitchen counter, on which sat a Cylon toaster. "Is this a freaking toaster that burns a picture of a freaking Cylon onto your freaking bread?" I squealed, eyeing it.

"You uh… You like Battlestar?" Leonard asked from the couch in a surprised tone.

"Uh, yeah. Can you tell?" I laughed to myself, walking back over to where everyone was sitting around the food and handing it to each other.

"I told you you'd like her." Penny smiled, passing me my plastic tray of seafood curry.

"I guess I am kind of a gee-"

"NO!" My bottom was centimeters from the sofa when the whole room shouted at me.

"What?" I asked worriedly, standing up and looking round.

"You uh… You can't sit there." Howard said to me. I frowned and look down at the stripy cushion.

"Might I enquire as to why?" I asked, sitting at the other side of the couch beside Howard.

"The wackadoodle." Penny said simply. I opened the lid of my food.

"What are you-"

I was cut off by the apartment door opening and two men walking in. One was a good foot shorter than the other, Indian, and abruptly stopped talking when he saw Penny and I. The taller one, who I guessed must be Sheldon, acted as if I didn't exist and sat in the place on the couch where the striped cushion sat.

"Hey Sheldon, Raj." Penny said. "This is Doctor Victoria Moore. Victoria, this is Sheldon Cooper and Rajesh Koothrapali."

"Nice to meet you both." I smiled, shaking Raj's hand first, who nervously smiled at me before sitting himself in a desk chair. I then leaned over Howard to shake Sheldon's hand. He looked at it a moment, as though considering it, before shaking it.

"Doctor Sheldon Cooper." He stiffly introduced himself.

"A pleasure Doctor Cooper." I smiled widely, before digging into my food along with everyone else.

The rest of the evening went swimmingly, I talked with Leonard, Howard, Penny and Raj, although technically Raj only spoke to me through Howard. Sheldon didn't talk too much, and when he did it revealed more and more of his idiosyncrasies.

"So you're an astrophysicist? What made you want to get into that field?" Leonard asked me, once dinner was over.

"Well, since I was a child I've been fascinated by space, the universe, how we became, but the reason I never became just an astrologist was because I've always had a knack for the science of things, how things operate, which is why I've also been successful and dabbling in engineering. But, I have an above average intelligence too so it would be illogical for me not to apply it to a worthy profession." I shrugged, and sipped my Sprite.

"I agree." Sheldon piped up. "From what I have heard from you this evening your intellectual level is far beyond that of most women of your age, and you seem to have achieved far above average, especially considering the male attention that could've distracted you."

I raised my eyebrow confusedly.

"Male attention?"

"Well, you are obviously a more than sufficiently attractive woman. I would say that most men would even consider you, for lack of better words, 'stunningly beautiful.'" I breath caught in my chest slightly and I flushed, he seemed completely unaware as he checked his watch. He stood, apparently oblivious to the stunned silence. "Good night everyone."

He left the room and disappeared into what I guessed was his bedroom, and no one spoke for a good thirty seconds.

"Uh, what just happened?" Penny asked in a slightly higher pitched tone.

"I'm not sure…" Leonard said slowly, looking with a puzzled expression at Sheldon's door.

"I think Sheldon just… Complimented someone."

... … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … …

"I still can't believe Sheldon said that." Penny said as we sipped wine in our pajamas that night.

"I was surprised too. But he didn't really seem to think much of it, it was more like I'm technically beautiful, not that he actually finds me beautiful." I said with a frown, trying to work out this strange man I'd just met.

"I don't know, it's about time Sheldon showed a little humanity."

"Come on, he can't be that bad." I sipped my wine. "I think he's kind of cute actually." I smirked into the glass.

"Really? Sheldon?" Penny said with a slight grimace. "He's like one of those pointy eared guys on Star Wars…"

"I think you mean Vulcans, and I think you mean Star Trek. I'll be moving out now." I joked, going to stand up, and laughed and tugged me back.

"Shut up, I don't know about that stuff." She rolled her eyes and I chuckled. "So… Sheldon huh?"

"Hey. Don't look at me like that, I'm just saying he's not totally unattractive. None of them are unattractive really…" I considered and took another sip.

"Even Howard?" She said skeptically.

"He's a little skinny but he's pretty good looking in that geeky kind of way."

"Unfortunately he's also creepy in that pervert kind of way." She mumbled, and I burst out laughing.

"You have a point there." I said, wiping my eyes. I put my glass on the table and refilled it, before doing the same with Penny's. "So, which one are you doinking?" I asked bluntly. She choked on her wine a little and spluttered.

"None of them!" She exclaimed incredulously.

"Oh come on. You've been living here for a while now, and I've seen the way Leonard looks at you. He doesn't blush anymore but his neck becomes flushed when you speak to him, and he fiddles with his hands which is an obvious hallmark of nervousness." I paused and sipped my drink before continuing. "But why would he be nervous now? He's known you a while and sees you a lot, most days in fact, so the only two logical explanations would be that either he's sexually attracted to you or he's allergic to your perfume. I'd go with the former rather than the latter." I took another long sip of my wine, and chose to ignore Penny's incredulous expression, as I smirked into my glass, thoroughly pleased with myself.

... … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … …

For the rest of the night, Leonard, Howard and Raj spoke freely without input from Sheldon.

"Did you guys realize how early Sheldon went to bed?" Howard pointed out looking at his watch.

"Yeah… That is weird." Leonard said, his brow furrowed.

"Maybe it had something to do with that there's a girl even more smoking than Penny living across the hall." Raj suggested.

"I wouldn't say she was more smoking…" Leonard contradicted.

"Nah, she is." Howard dismissed. "I mean, Penny's hot but Vicky's like… Angelina Jolie in Tomb Raider hot…"

Raj nodded in agreement.

The boys quickly forgot the original topic as they discussed varying degrees of hotness.
