So how is everyone doing? This is my first Big Bang theory fic, probably just going to be a two shot, I'm kind of a (very) late comer to the show. I'm roughly halfway through series 2, so that's probably about where this is set, anyway enjoy!

Sheldor the White Knight

Doctor Sheldon Cooper had been referred to as many things over the years, child prodigy, moonpie, the derogatory whackadoodle and, even if only by himself a superior mind. What had never been added to his resume, at least outside of any number of MMORPG's which he had partaken in over the years was Sheldon Cooper, savior of damsels in distress. What exactly had caused his ears to perk up at the sound of the shouting match taking place across the hall he was not sure. At this moment in time he was quite happy to deduce the reason why he was currently hovering at the apartment door was the fact that Penny and her latest Neanderthal had disrupted his work.

"How dare you!" Thud "Not even a movie producer you slimy lyling little sack of shit…Don't even touch me!"

Now Sheldon didn't know much about his neighbors latest tryst, but what he did know was that he had never heard her quite this distressed and angry, and even in what he considered a limited capacity as a rather new friend and neighbor, even just by way of proximity, he understood that the façade of anger would very quickly fade.

The physicist stole a quick glance back at his familiar comfy spot on the big leather sofa which was currently bathed in the soft glow of his laptop screen. Again he couldn't quite put his finger on why he was stood listening to world war three when he could have been attending to more important issues, the fabric of the universe for example.

Thud "Ow!"

Sheldon allowed himself a grim smile, ah yes it was because the girl next door was particularly fond of and more importantly in this case, accurate with her high heels.

Penny couldn't help but smile as Luke stood there rubbing the side of his face vigorously. To be fair Penny was surprised she'd even managed a glancing blow. She never really had been good at darts pissed. The man who had arrogantly invited himself upstairs took a step forward, he pointed at her with his free hand, a smile twisted by pain on his lips.

"Now toots" he had a thick Brooklyn Drawl, which above all else, was beginning to grate on his company. "Where there's blame there's a claim, I hope your willing to compensate." The grimace was replaced with a smirk as he took a couple of steps forward, arms thrown wide. Penny notice now how the sleeves of his cheap suit rode up and didn't quite fit. Would have been a nice thing to notice about an hour ago. Penny tried to make the berating voice in her head go away, at least for the time being she had a bum to throw out of her apartment.

Penny took a tentative step forward so that she was stood at the opposite end of a sofa to a man who was quickly rising up her "worst decisions ever list" She cocked her head slightly to the side and stared at the man, hoping to be the intimidator in this particular situation. "How about you leave before I make sure your able to claim on your life insurance?" her tone was calm and even but more than a little menacing. Despite her best efforts Luke took another couple of steps forward.

Once he had heard Penny unload her second shoe Sheldon had slipped out of 4A quietly, still not wanting to betray his presence but at the same time paying credence to the fact that normally the warning shoe was enough to get rid of Penny's unwanted guests. In two strides he had crossed the hallway, he tentatively pressed his ear against the blue wooden door which was currently the only thing keeping him from the barmy which he could still hear going on on the other side.

"You creep get out of my apartment!" Penny's voice stirred something in Sheldon, he wasn't quite sure what, but it was quite clear to him now that the reason he was standing on the outside of 4B is because he didn't like what he was hearing, not because it was a distraction, but because it was a worry. So much of a worry in fact that for the first time since the age of four Sheldon Cooper entered an occupied room without first knocking three times.

The rangy physics timed his dramatic entrance just in time to hear a man who he had never seen before, with hair in which you could fry chips, say a line which he found himself hoping against hope was not true.

"Movie producer, porno talent scout, you weren't so picky at the bar." It is thought that those who have greater cognitive reasoning skills are slower to resort to violence, but at that precise moment in time Sheldon felt more like acting Stephen Seagal than Stephen Hawking. He would have done too had Penny not saved him the effort. The punch, and that was what it was a full-bodied right hook that sent the sleazeball spinning straight into the Texas native.

Penny meanwhile was just stood, eyes wide with shock, not quite sure whether it was because of the punch or how nicely it had landed, or because Sheldon, who towered over her sparring partner had taken the man by a pinstriped shoulder and marched him from her apartment. Hopefully straight down the vacant lift shaft. Wait, when exactly had Sheldon turned up, what had he heard? Penny began to panic, the gravity of what had just nearly occurred sending a rush of blood to her head, with the distraction gone the wooziness of alcohol returned tenfold and alongside the dizziness and rush of emotions Penny shrunk to the floor of her apartment. She felt hot tears began to roll down her cheeks.

What had she nearly let herself do?

So that's chapter one, hope you enjoyed it. This feels like the first time I've written anything in ages so any feedback is gratefully received so please leave a review.
