If there was one thing, Penny thought, that Sheldon and I have ing common, it would be the hatred for buses.

Penny was on the bus heading to her apartment from a hard day's work at the cheesecake factory. It has been a week since Sheldon stole her car and took it to the mechanics and payed for the check-up and repairs. Sheldon paidformy car to be fixed, even to fix the check engine light, I mean who does that?! Penny thought.
Someone who knows that you hate being in debt to anyone, another voice in her head stated.

Pressed the bus-stop button and went off the bus. As she was walking toward her apartment building, she felt the pain everywhere around her body from paintball yesterday.

As Penny walked up the stairs in the apartment building, she couldn't help but smile at the memory of shooting Sheldon's cushion...Again. I do love making him squirm, thought Penny.

Penny stopped in her tracks when she saw a post-it on her front door. She grabbed it and read;

This is for the pain from paintball
- Sheldon Cooper

Uh Oh, Penny thought, what did he do this time? She grabbed her key and quickly opened the door. She gasped at the sight before her. She instantly thought of two things; laser tag except with string, covering the entire room, and the movie Entrapment with Catherine Zeta-Jones.

Compared to the other things they've done to each other, it wasn't much of an attack. The only thing Penny was angry about was the fact that he went into her apartment.

With a sore body, Penny painfully stepped, ducked, dipped and crawled to get to her room. To her relief her room was not tied up with string. She went to get change into casual clothes, and she saw the alarm; it was 1:50 pm. Penny instantly thought that Sheldon would still be at work.

Penny rested on her bed, hoping to have a little nap, but then Penny caught sight of another post-it, it was in front of all her cuddly toys. She grabbed it and read;

This is for shooting my cushion

-Sheldon Cooper

Penny looked around and wondered what he meant. And then she saw it; her favourite most priceless teddy bear was missing from the pile of toys!

Sheldon had sunk to a whole new level of low. Penny felt an anger that made her hands shake.

Penny grabbed scissors from her last draw and started cutting the strings. She went to the bowl where she kept the spare key to Sheldon's apartment. But Sheldon was a step ahead of Penny, because he took the key. So her next option was to drive to his...she stopped her train her thought again, being reminded that he had taken her car too. Penny started to get a headache' Leonard was right to say that Sheldon was one lab accident away from becoming a super villain.

She had to do something! So Penny decided to go for a walk, even though she was as sore as hell, she had to burn some of the anger inside her.

When Penny was about to go down the stairs, Sheldon's apartment door opened. To Penny's joy it was Leonard who opened the door.

"Oh Leonard thank god you're home!" she sounded happy, and then she thought about it and said, "What are you doing home?"

When Leonard saw Penny, he became nervous. Penny thought, he's afraid to speak to his best friend's sworn enemy.

"Well...um...someone stood on my glasses and broke them, so I had to come home," Leonard responded.

"I have some questions for you Leonard," Penny looked at Leonard expectantly and he just nodded.

"Firstly, are you aware that Sheldon went into my home?" Leonard gulped and nodded but quickly explained,

"I tried to stop him, really I did! But Sheldon is really strong!"

"It's ok Leonard, really. My next question is...," Penny looked concerned and worried, she came closer to Leonard and spoke softly, "Is my teddy bear...still alive?"

Leonard got closer and murmured, "hostage is alive, but in a tight situation. It is impossible to get it off criminal with the hostage."

A new plan formed in her head, if Sheldon wanted to play dirty, then Penny will play dirty.

"Can I come in Leonard?"Penny asked.

Leonard looked unsure, "I don't know Penny, you'll pass enemy lines, and Sheldon told me not to."

"So you're going to take orders from Sheldon?" Penny sounded sceptical.

"Yes...um...no..yes," Leonard was unsure.

Looks like it's up to my womanly charms, Penny thought. She stepped closer and touched his arm and put on a pout, "please, Leonard."

That was all it took for Leonard to blindly say, "Ok."

Penny went straight to Sheldon's room and burst the door open.

She walked in and looked around. What is personal to him that he would trade my teddy bear? Thought Penny.

She sat on Sheldon's bed, it was the most comfortable bed in the world, Penny thought. Then she saw a frame hanging on the wall, inside it; was the napkin signed by Leonard Nemoy. Penny had a sad smile on her face, when she remembered the feeling she had felt when Sheldon had hugged her. In the moment of the hug she had thought their friendship would last forever. But now, looking back, she could see that that statement was wrong.

Her teddy bear came back into her head, and went back to business. The napkin was a good hostage, she was about to take it when she saw something that could get her to an even deeper level of low, the wooden box that had all his letters from his meemaw. They were one of a kind, and priceless to Sheldon, it was just like her teddy bear. The perfect hostage for hostage trade.

Dr. Gablehouser sat impatiently listening to Dr. Winkle and Dr. Cooper complains about each other in his office. Why can't they get along? He thought.

"You're such a dumbass!" Leslie said. Thats why, he though, smiling to himself.

"Yeah well..."Sheldon really sucked at insults. Sheldon's cell in his pocket started to ring a Radiohead song.

He looked at the caller I.D; Penny then turned his cell off.

"Was it Penny?" Leslie asked smiling. Sheldon didn't answer because then Dr. Gablehouser's phone started ringing.

He picked it up and said, "Dr. Gablehouser's office."

He then handed the phone to Sheldon, unsurprised, "It's for you."

"Hello?" Sheldon said.

"This is Penny."

"What do you want Penny?"

"My teddy bear,"

Sheldon smiled and said, "Well you can't have it."

"I suspected as much. That is why I propose an exchange,"

"What could I possibly want from you Penny?"

"Your Meemaw's letters."

Sheldon froze, "what?"

"I have the letters from your Meemaw, right next to those letters, I have a match stick."

Sheldon didn't hesitate, "Where do you want to meet?"

"In front of the Golden Dragon. Bye" Penny hung up.

Sheldon handed back the phone in a daze, "I have to go," and went to the door.

Leslie asked before he left, "What about all the whiteboards you were hogging?"

Sheldon turned back and calmly responded, "Take them, I don't care," Then he left, leaving Leslie and Dr. Gableouser shocked.

"Wow," Dr. Gablehouser said bluntly, "We should get that woman to call more often."

Leslie didn't reply, she just kept her eyes on the door, looking genuinely worried.

Sheldon went to his safe, in his office and opened it, inside was Penny's teddy bear. He specifically took this teddy bear because he knew what it meant to her. It was the one toy that her dad had given her, that was more girly than boyish, which meant a lot to Penny.

He grabbed the teddy bear and scissors; if penny had a match stick to burn the letters, then he had scissors to rip the stuffed toy to shreds.

"Hey Sheldon," Howard and Raj said to Sheldon as he walked past, and they saw the scissors and teddy bear in his hand. Sheldon didn't notice them, he was too focused on where he was going.

When Sheldon turned the corner, They looked at each other, "No doubt heading toward another battle with Penny," Howard said.

"When is the war going to end?" asked Raj.

Then Howard asked, "My question is," he looked at Raj, "How is it going to end?"

Final battle next chapter... da da DA!!!!
