For all of you who did not get what Penny thought last chapter, I'm just gonna say this…it is possible to have sexual intercourse with multiple people. That is all, and if you still do not get it then…well, I don't know what else to say. Can I make it any more obvious?

And no, the next reviewer does not have to review in Klingon…but that would be AWESOME. I will seriously love you forever if you do it. Bernadette may not have let Sheldon do the wedding ceremony in Klingon, but I will let you review my story in Klingon! The power of Sheldon compels you!

…Moving on…

Sorry this took forever but I was busy, and then once I was finally ready to write this malware software took over my computer. Ugh. I apologize for keeping you all waiting.

Aaaand just read the disclaimers in previous chapters if you need too. Believe me, if I ever owned this show you all would know about it. Can't you just picture the headline now?

Chapter Nine: The Sibling Correlation

"So," Penny said to make conversation, sitting down in the chair with a bottle of water. "That was some date night, right?"

Leonard frowned. "Yeah," He said unenthusiastically. "Some night…"

There was a long awkward silence after that; Leonard and Penny exchanged a look, Amy thought back to see if she could remember anything from that night stood out, naïve Sheldon continued to pick at his food, and Raj looked from one to the other, pondering what they could've happened before finally giving up and going back to the Chinese.

Penny opened her mouth to try again with another topic, but she was cut off when the door opened.

"Hey guys," Howard and Bernadette walked in, their arms wrapped around each others' waists, and smiles on their faces. Besides them, was a girl none of them had ever seen before, except for Raj. Raj knew her all too well. "This is my sister, Adelaide," Bernadette said, gesturing to the little brunette.

Standing beside each other, Raj realized there were more similarities between Bernadette and Adelaide's physical appearances. While Adelaide was an inch or two taller and had brown hair instead of blonde, she had the same eye shape and color, same skin tone and bright smile. Outside of her office, Adelaide was even more beautiful, she didn't wear as much makeup and her hair was pulled down, curled a little at the ends – not unlike Bernadette's. She dressed a lot simpler, opting for a cotton shirt and blue jeans than a jacket and suit pants.

Adelaide surveyed the room, grinning widely. Once she finally met eyes with Raj, her smile faltered for a moment – just a brief moment – but then it bounced back, just a little wider and faker than before. She clasped her hands and glanced away from Raj's gaze. She might've been able to fool everyone else with that plastered on smile, but he didn't buy it. She knew him. She remembered him.

"Let me introduce you," Howard said, gesturing to each one of them as he spoke. "This is Leonard, Penny, Amy, Sheldon, and Raj,"

"It's lovely to finally meet you all. Bernadette has told me so much about all of you," Adelaide said. Raj would've bought this, but Adelaide's tone was a little higher and sweeter than it had been during their therapy sessions, and he knew this meant she was forcing it. Her eyes flickered back to Raj for a fleeting moment, almost as if she was trying to convince herself it was really him, and Raj looked down, embarrassed almost.

"I do wish you had told us you were inviting an extra person, Howard and Bernadette," Sheldon remarked with a hint of typical Sheldon annoyance. "It's just going to be like the pizza all over again-"

Bernadette opened her mouth to snap something about being polite to Sheldon, but Adelaide waved it off. "It's fine," She said. "I have to work tonight anyway." She whipped an iPhone in a geometric printed case out of her bag and quickly entered in her pass code.

"I'll walk you out-" Howard began after a small nudge from Bernadette, but he was cut off.

"No," Raj said before he'd thought it completely through. "I'll do it,"

Bernadette's eyebrows knitted together in confusion. "But-"

"That sounds lovely," Adelaide interjected, casting her older sister a glance. She looked back to Raj and he got up, holding the door open for her as she exited. He closed the door behind them, keeping a foot of space between him and Adelaide.

Once the door was shut, Adelaide spun around to face Raj. "Oh my God," She said, stunned.

Raj didn't know exactly what to say. "Adelaide, I'm so sorry…"

"What are the chances?" Adelaide said in shock, shaking her head. "Oh God…"

"Why didn't you rat me out in there?" Raj asked. "You didn't have to act like you didn't know me, you could've told everyone about what happened with us,"

"And what good would that have done? It's not like it would've changed anything,"

Raj thought about this. "Yeah," He said finally. "You're right,"

"Of course I'm right," Adelaide added teasingly with a smirk. They both laughed uneasily, and then it was silent for a second. "…Can we just try to start over?" Adelaide finally asked. "You seem like a nice guy and…and I'd like to try and be friends. It's not like we can avoid each other, right?"

"Right," Raj affirmed. "Friends…" He swallowed. "Friends it is,"

Adelaide smiled and gave Raj's hand a reassuring squeeze. "I'll see you later Raj," She turned around and started off, pressing another button on her cell phone.

"See you later," Raj said, rather delayed. He watched her take the stairs two at a time on her way down, his skin still tingling from where she'd touched him.
