Chapter 3 – benefits of a hyperventilating theoretical physicists

She feels happy. No that's not good enough…ecstatic. With Mumford and sons blaring through her poor sound quality speakers, singing along word for word. As she reaches 2311 North Los Robles she absent mindedly notices that Leonard's car isn't in his car park space.

She is kind of relieved that he is not really. Before she began to hide from the guys she noticed that Leonard was starting to get that glint of hope in his eyes whenever she saw him. Hope that she would go on another date him. The first one was bad enough. He is a sweet guy and he is a lot better than she has been with in the past, it's just that she doesn't see it going anywhere and she doesn't want to lead him on and hurt his feelings. Especially, when she secret has a crush on the Dr Wacka-doodle. His room-mate. After persisting to get the first date that she regrets why would she give in to another one.

Anyway ever since that first date she didn't need to go on another to get to know him better to test the waters, so to speak, because it has opened a very big door that she would have to be stupid to walk through. I mean just after one date she can already see how jealous and over possessive he is. He caught her on the stairwell a few weeks ago with an on friend and flipped. Stuttering questions left right and centre. Who is he? Why are you with him? Where are you going? Before she could even answer him, he had already sulked back up the stairs past them and into 4A to whine to his poor room mate about it.

Speaking of Sheldon, he hasn't even tried to find out about why she hasn't been attending HALO night and laundry night. Surely she has disrupted his precious schedule? I guess I am about to find out now. She thought to herself as she basically flew up the stair with excitement and adrenaline fuelled happiness to the fourth floor.

She didn't knock on 4A as she reached the door. Why would she? She never did so why start now? However on this occasion, she kind of wished that she had but she was too busy bouncing into the room.

From her position a few inches away from the door, she could see the back of her wacka-doodle's lanky body in front his whiteboard with his back to her. In her excitement and adrenaline fuelled happiness she barely noticed the way that Sheldon's shoulders were shaking. In fact she had to give herself a few calming breathes to establish why he wasn't already admonishing her for her bombardment. Especially with his Vulcan or whatever the guys called it hearing. Surely he heard her. After she had composed herself enough for Sheldon to find tolerable, she instantly noticed the way that his whole body was trembling and heaving. Concern instantly replaced her excitement as she attentively got closer to him and read his facial expression.

Sheldon POV

He was hyperventilating beyond control now. He has been in this state for 20 minutes and 34 seconds and he is surprised that he hasn't become unconscious by now.

He couldn't see anything other than his equation on the whiteboard in front of. Even though there were countless others scattered around the board with graphs squeezed into the corners and triangles and numbers, it was all blank in his eyes and all he could see was THE equation. His eyes had begun to blur with unshed tears that had formed because of his prolonged starring competition with his whiteboard. The lack of blinking and adequate breathing ability was definitely the reason for his tears. He would never admit that they were happy tears because that was hokum and something that penny would say.

Suddenly he realised something. One question. What now?

He had done it…

His life's goal was complete…

He had done it!

Everything crushed him again and new emotions hit him. A fresh and stronger wave flooded him and he hyperventilated more severely and harsher. He started to feel light headed and queasy. He needed something to pull him back to earth. To reality.

Penny POV

His face was hit with new emotions. She couldn't even keep up. It terrified her. He started to hyperventilate even stronger and heavier than before. If that was even possible? How long has he been like this? Why is he like this? Where are the rest of the guys? How is he still standing?

He face was paler than a ghost now. That's it, she has got to do something!

''Sweetie?'' she approaches slowly and speaks softly to not scare him.

…nothing

''Sheldon, sweetie?'' she asked a bit louder with more confidence.

…still nothing. And he is getting paler. Where is the blood in his face going? Maybe I will ask him later. But what if she can't ask him later? What if there isn't a later? He needs to breathe!

''SHELDON!'' she screams. It's the only way to get her mind to stop going further into a dark hole.

If this is a Bazinga I am going to kill him! Penny thinks to herself grabbing his shoulders.

One final resort and a part of her are happy that it came to this. She has been waiting for this for too long. Hoping it brings back her wacka-doodle and he will give her a strike. At least he will back. But then she looks up into his eyes again for brief second. Why is he so happy? His face is full of wonder, shock and amazement as if he just solved the biggest mystery of the universe. Its either this or she calls his mother because her son is broken. She would much rather do this though.

She wraps one arm around his waist to keep them both steady as the other reaches up to his left cheek. This can be my congratulations present from him she thinks to herself as she leans up on her tip toes and pulls his lips to hers gently and slowly. Savouring the moment as it will probably never happen again once he realised the amount of germs.

They were so soft and warm. Although she expected as much from the lanky physicists with all of his sanitizer and germ repellent products that he covers himself in. This felt so right somehow. This didn't surprise her though. What did surprise her were the long, strong confident arms that firmly wrapped around her waist in a tight embrace whilst he bends his face closer towards hers, deepening the kiss with passion and thirst.

If that wasn't a big enough shock, then Sheldon's tongue sliding across her bottom lip asking for access a few seconds later was definitely enough to finally knock her socks off.

Here is it, the 3rd chapter. Probably some mistakes but who can she understand what I'm trying to bring across. The next chapter will be what Sheldon thinks of the situation...i will post it tomorrow morning or lunch time depending when I get up :) thanks for the review and keep them coming i want to know what your input is and some of your ideas could help me make the next couple of chapters more enjoyable :) x
