1. Penny furtively looked at her watched, she had to be at the Cheesecake Factory in less than an hour but she really wanted to keep digging into Leonard's personal business. She'd known him for so long but never really got to know him. While his life appeared to be an open book, it was written in Klingon.

Sheldon prepared a cup of tea for Cassandra while Lenore stared at him in awe.

"My friends, Howard and Rajesh are coming over a little later..."

Cassandra gave a broad smile, "I'm looking forward to meeting your friends! It's tremendous that your friend's designs have gone into space."

"He built a toilet," Sheldon yelled from the kitchen, "and he built it badly."

Cassandra smirked at Sheldon's back before continuing, "I still have the People Magazine featuring Rajesh."

Sheldon looked ready to say something but Lenore had begun batting at his knee caps yelling, "Ticka, ticka."

"Why is this child hitting me? How do I make her stop?"

"She's tickling you, Sheldon," Cassandra explained, "Laugh."

"Why would I laugh? She's not tickling me, she's hitting me."

"It's a cute behavior and I don't want to extinguish it, so, laugh."

Cassandra spoke with a degree of authority that even Sheldon could not ignore. When he gave his breathy version of a laugh, Cassandra turned to Leonard and mouthed, "What was that?"

Leonard smiled, "It's his laugh, leave him alone."

"That's not a laugh," Cassandra whispered, "That's an asthma attack!"

"It's a cute behavior, and I don't want to extinguish it."

2.

Leonard all but shooed Penny out the door as her shift approached but Cassandra was just so delightfully odd, she didn't want to miss the show.

"I really am looking forward to meeting Rajesh..."

"Oh, I wouldn't be too excited about meeting Raj..." Leonard looked distinctly uncomfortable.

Penny poked her head back in the door and shared Cassandra's interested look.

"Raj has already declared his intention to... I dated Raj's sister for a while and I'm pretty sure he was kidding about bringing shame to the Hofstadter name but..."

"I'll try to resist his charms," Cassandra laughed, "Did you tell him I was married?"

"Yes," Leonard said, "I also said you were thirty-eight."

Cassandra frowned, "Why did you pad my age... Did you say I was thirty-eight so he wouldn't think of me as a potential sex partner?"

Leonard shrugged.

"So, if I were five years older, I would no longer be sexually attractive to men?"

"Is that what you're saying?" Penny added with a smile that might have read as evil.

Leonard threw his hands in the air like he was surrendering and Cassandra moved on.

"Which girl was his sister?"

"Priya," Leonard, Penny and Sheldon answered in unison. Penny felt a little better than Cassandra didn't know Priya's name when she had been Leonard's most recent girlfriend. Maybe Cassandra had a bad memory for names.

"Oh, that bitch."

"She wasn't a bitch," Leonard snapped with a quick glare for Penny and Sheldon who remained silent on the subject, "She was looking for something different from what I was looking for..."

"Like the girl who ditched you at a bowling alley and ended up sleeping with one of your friends?"

Penny really needed to get to work and did so, post haste.
