"Yeah… Okay… Okay, I'll see you when I get through the gates. Bye." Smiling, Rosalind hung up her phone and adjusted the strap of her messenger bag which hung snugly over her shoulder. As much as she loved her older brother, he could be way too overprotective sometimes.

Rosalind, or Rose as she preferred to be called, slowly made her way through the airport. The lines dragged on for what seemed like forever, which irritated her to no end. All she wanted to do was see her brother Leonard, whom she hadn't seen for five years now. She had only been able to talk to him on the phone, or video chat with him every once in a while when their schedules happened to afford them the time. Rose's irritation quickly faded when a mess of brown hair and glasses perched precariously on a nose caught her eye.

"Lenny!" Rose grinned, calling out to her brother who stood next to the front doors before rushing over to him.

"Rose!" Leonard laughed, spinning his sister in a circle while she laughed with him.

Leonard and Rosalind Hofstadter, though siblings, couldn't have been more different from each other sometimes. While Leonard was always awkwardly sweet and polite, Rose was blatantly rude to those she didn't like. Leonard was short while Rose was tall. Rose pursued the arts of Music and Acting, while Leonard pursued the 'art' of Experimental Physics. But despite all of their differences, there was no mistaking the two for anything but siblings. Both wore somewhat blocky black glasses, and were both in love with Comic Books and such. They grew up playing Superhero when they were little, and then reenacting their favorite scenes from their comic books. Rose always had to be the villain though; Leonard wouldn't let her be anything else.

"I've missed you so much Lenny!" Squeezing her brother tightly, Rose pulled away with a smile as she adjusted the bag on her shoulder.

"I've missed you too. Come on, I already put your bags in the car. Penny's really excited to meet you." Leonard ushered Rose out the doors of the airport, and she bit her lip nervously. This was the first time she would be meeting her brother's girlfriend.

"W-Wait! Leonard, you know how I am with new people!" She hissed, falling silent when they approached a pretty blonde woman that was leaning against what Rose assumed was Leonard's car.

"Don't worry. She's going to love you." Leonard smiled brightly, pushing his sister forward as Penny pushed off of the car and walked towards them with a smile.

"Hi! I'm Penny, and you're Rosalind right? Leonard's told me so much about you, I feel like I know you already." Penny came forward and hugged Rose tightly, catching her completely by surprise.

"Umm… Thanks. You know, it's hard to believe you're my brother's girlfriend. I mean, he's not exactly Prince Charming." Rose smiled, relaxing as Penny laughed at her words. She had a feeling they would become close friends, despite Rose's first instincts to run from the scene.

A few hours later, they arrived at the apartment building where Leonard lived with Penny and his roommate Sheldon. Rose had never met Sheldon before, unless you counted the five seconds she saw him when Leonard was video chatting with him when had gone to visit his Mother and Rose about six years before. Upon entering the building, Rose immediately headed towards the elevator, but stopped when Leonard grabbed onto her arm.

"Elevator's broken. Long story." Penny announced, and Rose quietly frowned as she followed them up quite a few flights of stairs.

"Leonard, you should have let me carry at least one of my suitcases." Rose sighed, shaking her head at her brother as he paused in front of a door marked 4A.

"Nah, I-I got it." He wheezed, and Rose pulled his inhaler from his bag pocket and handed it to him with a smirk.

"Come on Wheezy. Breathe it up." Taking the key from his hand, she unlocked the apartment door and opened it widely.

"Sheldon! Come help Leonard with his sister's bags."Penny called out, sitting on the couch with a lazy yawn. Rose laughed slightly at Penny's behavior, and set her bag on the left side of the couch, barely hearing Leonard's wheezy protests as she did so.

"And why on earth would I do that, Penny?" A slightly annoyed voice rang through the room, and Rose turned her head to see a very tall man enter the room from the direction of the hall.

"Because it's considered polite to help your Roommate. Wouldn't that be found in some way or another in your Roommate Agreement?" Penny shot back, and Rose chuckled. Life definitely wouldn't be dull here, of that she was sure.

Piercing cobalt blue eyes met the stormy grey depths of Rose's eyes, and Sheldon was momentarily stunned. He allowed himself to wonder who the creature in front of him was. Raising her hand in silent greeting, Rose walked over to the white board off to the side and snorted lightly. "What's all this mumbo jumbo?" Rose remarked before Leonard could stop her. Little did Rose know, she had just called Sheldon's board on String Theory mumbo jumbo.

"…" Glaring silently at Rose, Sheldon, Rose assumed, moved and grabbed one of Rose's suitcases from Leonard who had finally stopped wheezing long enough to enter the apartment.

"Thanks. I can take it from here though if you just point me to my room." Rose remarked, stepping forward and reaching to take the suitcase from his hands.

"My mother raised me to be a gentleman, and to never ignore a damsel in distress, even those who may not be intelligent enough to recognize such chivalry." He remarked calmly, and Rose felt her jaw drop. Who the hell did this guy think he was?

"I'll have you kn-" Rose started to reprimand him, her anger fueled by her outrage when Leonard quickly clamped his hand over her mouth.

"She appreciates it Sheldon." He quickly stated and Rose narrowed her eyes before biting firmly down on her brother's hand.

"I certainly do not!" She growled, glaring at Sheldon's back as he disappeared down the hall.

"Look, Rose. With Sheldon you kind of just have to roll with the punches. He's not exactly socially adept." Leonard explained and she shook her head furiously.

"No. That's not okay. I am not going to just sit here and let him insult me like that." Penny stood and motioned for Leonard to step back.

"Honey, I know exactly how you feel. I was the same way when I first moved in across the hall. But once you get to know him? He wasn't insulting you. Or at least he wasn't trying to. He was just a little hurt that you called his board mumbo jumbo. That's just how he is, really." Penny tried to soothe Rose's frazzled nerves and Rose took a deep breath.

"Fine. But I won't let it slide next time." She sighed, running her hand through her brown tresses before throwing it up into a tight ponytail. Whenever Rose was stressed out, she had to pull her hair back from her face. It helped her to think. It was also a tell that she was seriously irritated, as Leonard knew all too well. During their childhood he had been witness to that reaction many a time. Forcing a smile, Rose picked her bag up off the couch and took its place on the far left end.

Settling in to the cushions, Rose yawned loudly. "I think I might take a quick power nap guys. Jet lag is starting to catch up with me." She murmured softly, her eyes already starting to drift closed. It seemed she had just started to sleep when an irritating voice cut through her consciousness.

"You're in my seat."
