Leonard shook as the sounds from Sheldon's room died down again. He'd sat in the kitchen and listened through the remainder of the night. Penny's screams haunted him. He'd never managed to elicit such sounds from her. When would the damn stuff wear off?
When they finally emerged Sheldon was wearing his pajamas and Penny was wearing Sheldon's robe. Their hands were linked and swinging between their bodies. Rumpled and exhausted, they still looked perfectly happy together. Leonard ground his teeth, relishing the pain in his jaw.
"Good morning, Leonard." Sheldon smiled at him.
"Not from where I'm sitting." Leonard snarled.
Penny blushed and looked away, her perfect, white teeth pressed into her bottom lip. Her short hair ruffled out from her head in little curls like an antique gold crown. She was a vision, and he wanted to destroy her.
"Feeling the shame, Penny?" Leonard smiled insincerely at her.
"I'm sorry for hurting you, but I'm not ashamed." Penny met his gaze and raised her chin.
"Do you think he loves you? Really?" Leonard sneered.
"Leonard, stop this." Sheldon stepped in front of Penny. "We both hurt you. We are aggrieved to be the source of your pain, but denying our true emotions was no longer an option."
"Your true feelings? That's rich." Leonard chuckled. "You don't have feelings. I drugged you. That's the only reason you even touched Penny."
"You little shit." Penny surged toward Leonard with a vicious snarl. "What did you give him?"
Sheldon grabbed her and pulled her back flush against his chest. She stopped struggling immediately. Her body went lax in his arms even as his mind churned.
"The Yoohoo. We both drank it." Sheldon closed his eyes. He'd promised his mama not to use drugs, and Leonard had made him a liar. "What precisely does your drug do, Leonard?"
"No, I'm not trusting this little shit." Penny turned in his arms and looked up at Sheldon. "We need to go to Bernadette. She'll know what tests to run."
"Run along." Leonard flipped his fingers at them. "When the drugs run out and you two can't look at each other, I'll be here laughing."
Penny stilled. Sheldon dropped his eyes down to meet hers. Her eyes were distant, but he could easily determine that she was using the full force of her intellect. She turned toward Leonard and stared. Her gaze narrowed and her hands fisted at her sides. The small man began to crumble.
"You wanted to drug Sheldon." Penny tilted her head and watched Leonard stutter but say nothing. "Why?"
"I wanted him to let Amy move in with him." Leonard snarled. "She was supposed to be the one that went to bed with him."
"This wasn't a roofie. I remember everything." Penny tilted her head. "Where did you get it?"
"It's experimental." Leonard shrugged and stepped back. He didn't like Penny's sudden ferocity.
"You gave Sheldon an experimental drug?" Penny grabbed his shirt and pushed him up against the fridge. "You gave him something with no idea how it would affect his mind? Did Bernadette give it to you?"
"Of course not. She's too ethical. The drug doesn't seem to have hurt either of you." Leonard tried to slide out of Penny's grasp.
"He's probably one of the smartest people ever, and you drugged him?" Penny shook him like a rag doll. "What if you've hurt him?"
"Let him go, Penny." Sheldon swallowed audibly.
"No." Penny tossed her head. "I'm not done with the little bastard yet."
"When he voids his bladder in the kitchen, you will be the one cleaning it." Sheldon crossed his arms over his chest. "Need I remind you of his copious digestive issues? It will not be pleasant."
"Fine." Penny relinquished her hold on Leonard. "We will go and see what his wonder drug is actually doing to us and then I will finish this."
"Have you addressed your vehicle's need for maintenance?" Sheldon ignored Leonard's scramble for his inhaler.
"No, I haven't." Penny shrugged. "Is that going to be a problem?"
"The light is on, Penny." Sheldon tilted his head and examined her for a moment. "It is already a problem."
"Yeah, yeah." She waved her hand at him playfully. "Do you want to ride the bus?"
"The odds of your car causing me injury are slightly less than the odds of a virus infecting me on the bus." Sheldon sighed. "I suppose I must chance it with your car."
"You're just going?" Leonard struggled to his feet. "This is just done?"
Penny spun around on the balls of her feet. She took two steps toward Leonard when Sheldon's hand closed on her shoulder. Sheldon stepped forward and pulled Penny into his arms.
"This was over when you decided to drug me." Sheldon seemed far more threatening than usual as he looked Leonard over. "I have forgiven you for many things over the years, but this recent attack proves I was wrong. If this drug has done any lasting harm, I will notify the authorities. As it stands, I will be calling your mother."
"Penny, we were engaged." Leonard slumped against the fridge. "How can you just walk away?"
"It's easy. One foot in front of the other. I'm not going to feel bad about leaving you this time. You drugged Sheldon. It's selfish and childish. I'm no genius." Penny held up her hand to stop Sheldon's comment. "But I know you are not ready to be in a grown up, real relationship if you confront problems like this. How could I ever trust you?"
"I was just trying to make it easier." Leonard took a step toward her.
"I don't know a quark from a quasar, but I know the easy way is usually the wrong way." Penny sighed. "It's over."
