Chapter Twenty-One

Katie ran her fingers through her sex-tousled hair. Even though it had only been her second time, last night was amazing. It had hurt like crazy, but she smiled just thinking about it. At least she'd found the right person to do it with.

She pulled on yesterday's clothing (a black Green Day hoodie, jeans so faded they were white, and black Converse) and walked into the kitchen, where Leonard was fixing hot tea and waffles.

"Hi, Leonard!" Katie chirped cheerfully, sitting down in the chair.

He turned to her. "Could you be any louder? Jesus Christ."

"What can I say?" She grinned. "The walls are pretty thin here," she said jokingly.

"Did he yell your name?" Leonard said in a mock-seductive tone.

"No," Katie said with a smirk, "but he yelled your mom's." She snapped her fingers. "Yes, I just went there! Got em!"

"Very mature," Leonard scoffed.

Penny entered the scene. "Things were a little loud last night," she said through a yawn.

"Oh, did I keep you up?" Katie batted her eyes at Penny. "I'm sorry."

Penny looked at Leonard. "Have I told you how great your hair looks today?"

"I can probably guess."

"Where's Sheldon?" Katie asked, suddenly noticing Sheldon's absence.

"Uh, he had to work," Leonard replied. "But he told me to tell you he loves you and he has a surprise for tonight."

Penny looked at Leonard in shock. "Seriously?"

"Yes, seriously," Leonard said. "Katie is in love and it's mutual."

"That's a shocker," Penny said simply, then turned to Katie. "When you first came here, didn't you mention wanting to become roommates with me?"

"Yes, but aren't you and Leonard moving in together?" Katie proposed as Leonard handed her a cup of tea. "Thanks." She took a sip. "Ouch! Hot!" She grabbed a napkin and dabbed at some of the tea she'd spilled in shock on herself.

"It's called hot tea for a reason," Leonard said wryly.

Katie ignored him, taking a slower sip of her tea.

"Yes, but maybe you'd like to move in temporarily since things may be a little awkward," Penny explained.

"True," Katie agreed. "It isn't a threesome, after all."

Leonard winced, his eyes wide behind his glasses. "Okay," he said. "Ouch. You just ruined it all for me."

Katie smirked and flicked her finger at him.

"Alright, when do you want me to move in temporarily?" Katie asked Penny.

"Sometime this week," Penny replied. "Is that okay?"

"That's great!" Katie jumped up and hugged her friend. "Thank you, Penny. Maybe Sheldon and I will get our own place someday."

"How are we gonna tell him that we're moving?" Leonard asked, always the one to worry.

"Don't sweat it," Katie said nonchalantly. "He'll get over it."

"Katie, Sheldon just doesn't 'get over' things," Leonard told her. "He gets fixated on things so much that he obsesses over them, and then, it slowly consumes his soul."

"We'll explain it to him," Katie said. "If he doesn't like it, I'll stay for a little while longer, but then move in."

"Good idea," Penny agreed.

"So, when are we gonna tell him?" Leonard asked. "And how?"

"I'll tell him over the surprise tonight," Katie confirmed.

"Why do I have a feeling that I know what that 'surprise' is?" Leonard quipped bitterly, and Katie slapped him on the shoulder.

"I would walk 500 miles, and I would walk 500 hundred miles just to get to you!" Katie sang loudly, applying shampoo to her hair. The Proclaimers blared through the radio speakers on the sink.

"I'm gonna be the man who-"

*knock knock knock* "Katie."

"Who wakes up next to you-"

*knock knock knock* "Katie."

"I'm gonna be the man who goes along with-"

*knock knock knock knock* "Katie."

Katie sighed, reached out of the shower, and turned off the radio. "What, Sheldon?" She wasn't too happy that her magnificent performance had been interrupted.

"The surprise is almost ready for you. Hurry up!"

"Okay!" She turned the radio up again.

"But I would walk 500 miles-"

*knock knock knock* "Hurry up Katie."

"-and I would walk 500 more-"

*knock knock knock* "Hurry up Katie."

"Just to be the man who walks a thousand miles-"

*knock knock knock* "Hurry up Katie."

"-to fall down at your door-"

*knock knock knock* "Hurry up Katie."

Katie sighed in exasperation and turned the shower off, pulling the towel around her.

*knock knock knock* "Katie."

*knock knock knock* "Sheldon." She knocked back, mimicking his knocking pattern.

The knocking was now more persistent. *knock knock knock* "Katie."

*knock knock knock* "Sheldon."

*knockknockknockknock* "KATIE!"

*knockknockknocknock* "SHELDON!"

*knocknockknockknock* "KATIE!"

*knockknockknockknock* "SHELDON!"

*knockknockknockknock* "KATIE!"

Katie opened the door and smirked.

"That's just wrong," Sheldon said.

"Hello, Sheldon." Katie laughed.
