Disclaimer: If I owned the Big Bang Theory, it would be all Penny/Sheldon and Raj/Howard. Sadly, I don't.

Author's Note: New chapter! Thank to those who took the time to review! There will be some Howard/Raj in this chapter and some Leonard/Leslie!

Penny smiled at Sheldon as she walked into his and Leonard's apartment. Sheldon glanced at her and nodded as he sat down. She sat down next to him. He looked so darn cute in his Superman t-shirt.

'Woah, where the frack did that come from?' Penny thought. She took another look at him. He did look cute, she decided. Almost...hot.

"Penny." Sheldon said, rousing her from her thoughts.

"What's up, sweetie?"

"My mother is coming to town tomorrow and seeing as I don't drive, would you mind picking her up from the airport?" Sheldon asked.

Penny gave him a warm smile and could have sworn she saw him blush. "Of course I'll pick her up sweetie. What time?"

"She said her plane would be arriving at two."

"Okay, Sheldon. I'll be there." Penny smiled again and this time she definitely saw a blush. Did Sheldon have...a crush on her? No, no fracking way. This was Sheldon Cooper. He was practically a robot. He didn't get crushes.

'What if he does like you? How do you feel about him?' She thought. She decided to try an...experiment. Just to see if Sheldon liked her. She leaned her head on Sheldon's shoulder.

The physicist stiffened, but didn't push her off. Penny laced her fingers through his and he didn't pull away. 'Okay, time to kick things up a notch.' Penny thought.

She wrapped her arms around his waist. Then he really shocked her. Sheldon wrapped his arms around her. They were snuggling! Penny looked up at him. He was staring at her, not paying attention to the movie.

Penny reached her head up. He was leaning towards her and their lips met in the middle.

Penny pulled away. "I...uh...gotta go." She fled the apartment. Once out in the hall, she leaned against the wall. Howard and Raj were coming up the stairs hand in hand. Howard kissed Raj on the lips, not noticing Penny.

"Holy crap on a cracker." Penny said. Since when were they in a relationship?

"Penny! Uh...why aren't you inside?" Howard said, blushing. Raj looked at his shoes, unable to say anything.

"Sheldon kissed me!" The blonde blurted out.

"What? Sheldon? Was he drunk?" Howard said, shocked.

"No! And I kissed him back!" She said, almost crying now. Why had she screwed everything up? She didn't want to lose her whack-a-doodle! Wow, when did he become hers?

"Do you like him?" Raj said, his voice barely above a whisper. Penny looked at him, shocked. "Oh, ever since Howard and I... Well now I can talk to women." He explained, blushing again. Howard wrapped an arm around his shoulders.

"That's the problem! I think I do like him!" She said, crying now. Penny knew it was the truth. Sheldon was neurotic, obsessive, and controlling but he was hers. She loved him.

"Well, I see the way he looks at you. He loves you. It's obvious." Raj said quietly.

"Raj, what am I going to do?" She cried. Raj stepped away from Howard and caught her as she fell.

"Penny, you have to tell him." Raj whispered in her ear.

She let go of Raj. "I know. So, when did you become a couple?" She said.

"Oh, about a month now. Right, Raj?" Howard said.

"Right. Sorry for not telling you. We didn't want anyone to know." Raj said apologetically.

"It's all right. Well, I gotta go." Penny ran into her apartment, almost blinded by tears. How could she be so stupid? She realized now it had never been Leonard. It was always Sheldon.

Sheldon. How had she been so blind? He had always been there for her. Leonard hadn't. Now she had embarrassed herself and potentially destroyed two friendships that night.

When she had broken up with Leonard, it broke his heart. Penny knew it was the right decision, but it hurt to see him like that. That was about two months ago. Now he was with Leslie but she knew he still had feelings for her. She would have to talk to him.

Oh, crap! She had to pick up Sheldon's mom tomorrow! Maybe she should call and...no. She had to face Sheldon eventually. Might as well be sooner rather than later.

Penny went to bed, feeling exhausted and drained. She flopped onto her bed, not even bothering to change her clothes. Penny fell asleep, hoping things would be better in the morning.
