I do not own the TBBT or any of the characters (I wish I did, though…)

Leonard was woken up by a loud thump coming from the living room. He looked over at his clock, 2:34 am. What the hell was that? he thought. Was it Sheldon? Was Sheldon okay? Leonard put on his glasses and jumped out of bed.

"Sheldon?" Leonard called from his bedroom doorway.

"What?" he heard his roommate reply from the end of the hallway. Leonard began to walk down the hallway towards the taller man and asked, "what are you doing?" He approached Sheldon from behind quietly.

"I was going to—" Sheldon turned around unexpectedly. What happened next was pure chance, but if you were Sheldon you would see it as factors that added up like this: Leonard had his head tilted up at a little too perfect of an angle. Sheldon had his head tilted slightly down at too perfect of an angle. The two men had been standing a perfect distance apart, not too far away and not so close that they were touching. Both men were tired. Both men were not expecting these factors to add up.

"I was going to—" as Sheldon turned he was stopped in mid-sentence by the shorter physicist's lips. They were unintentionally kissing.

Both men were so tired that they didn't know how to react, so they both froze without pulling away. It wasn't like their lips just brushed against each other, this was a real kiss, weather they wanted to realize it or not. They stood there, confused, shocked, and bewildered. They stepped away and stared at each other.

"Well I can tell you I wasn't going to do that!" Sheldon exclaimed after both men stared at each other for a moment. Leonard didn't reply, he just looked in Sheldon's eyes. He never really noticed them before, they were so…blue. Like an ocean that Leonard could drown in, like the night sky when a full moon brought it to life. Sheldon looked down at the ground and Leonard noticed they looked like they were carved from sapphires. They were like— Stop it, Leonard!

He snapped out of…whatever that was, and took a deep breath. "Let's pretend that didn't happen."

"Agreed," Sheldon replied, and hesitated before walked past Leonard and entered his room. "Goodnight," Sheldon called before closing the door. You mean morning, Leonard thought. If Sheldon made the mistake of saying 'night' instead of 'morning' then he must've been as weirded out as Leonard. Leonard walked slowly back to his room and crawled into bed. Why hadn't he noticed Sheldon's eyes until that particular moment? This was going to be a long night.

Sheldon woke up with a cloud of confusion lingering over his head. Why was he confused, though? Oh, that's right, he remembered the happenings of last night. The kiss, the awkward silence, the whole thing was just awkward. He looked over at his clock, it was a whole hour before he usually got up. He threw the covers off himself and got dressed. He followed his normal routine even though it was an hour earlier. He made a bowl of oatmeal and ate it in silence. While he ate he tried to figure out how to pretend that nothing happened. When he was done he cleaned the dishes and walked across the hall. It was definitely before eleven AM, so he might get punched in the throat, but he decided to risk it anyway.

Knock, knock, knock

"Penny?"

Knock, knock, knock

"Penny?"

Knock, knock, knock

"Penny?"

Penny pulled open the door and looked up at the tall figure that stood in front of her. What did he want this early in the morning? She forced a smile, "Hiya, Sheldon."

"Hello, neighbor. I have a question for you," Sheldon said and held his hands behind his back, he was clear from punches.

"What is it?" she asked and tightened the tie on her robe.

"How are you supposed to pretend that something that happened didn't happen?"

After yawning, Penny said, "What?" She hadn't really been listening, so she was totally lost.

"Something happened and I am supposed to pretend that it did not happen, when in fact, it did happen."

"What happened?"

"I can't tell you that."

"Why not?"

Sheldon made air quotes as he spoke, "because it 'didn't happen.'"

"Sheldon, you're not making any sense!" Penny complained.

"Yes I am!" he insisted.

"Look, there's no way I can help you without knowing what happened."

Sheldon frowned and considered what she had said. She had a point. "Maybe you should come in," Penny let Sheldon in and pushed the door closed. They sat down on her couch and Penny looked at him with hopeful eyes. Sheldon hesitated.

"C'mon Sheldon! Do you want me to help you or not?"

There was a long pause before Sheldon finally told her. "Leonard and I accidentally…kissed." Penny's mouth fell open.

"WHAT? HOW?" She seemed to be fully awake now.

"When I turned around Leonard was standing right behind me and I was slightly bent over and he was looking up and then our lips collided together," Sheldon was quite distraught on the matter but he tried desperately not to show it.

"Wow…" Penny was shocked.

"And I'm supposed to pretend it didn't happen! How am I supposed to do that?"

"To start, you could've not told anyone," Penny suggested, and Sheldon glared at her. "I don't know, Sheldon! Just don't bring it up, don't mention it when some asks you 'what's up?' Go about you life like you did before it happened." Sheldon considered this for a moment. "Happy now?" Penny asked him.

"Not particularly, but I suppose your answer was somewhat satisfactory." Sheldon stood up. "Thank you, Penny."

"Your welcome, sweetie." She smiled and he got up to leave. "Oh, wait, Sheldon. I'm goin' on a date tonight so I won't be comin' over for Thai food later. And don't worry, I won't tell anyone about what 'didn't happen.'"

"Alright," he replied, left her apartment, and strode across the hall. He walked into his apartment and stopped to look at his whiteboard. He didn't realize how long he had been standing there running equations through his head until his roommate pointed it out to him.

"Are you going to stand there all day, or do you plan on going to work?" Leonard asked as he walked into the room.

"Oh hello, Leonard. I didn't hear you coming," Sheldon commented without his eyes leaving his whiteboard.

"You didn't hear me coming when I made coffee and ate, either," Leonard told him. Sheldon turned around and faced the shorter man, careful not to run into him again. Leonard was fully dressed and held his car keys in his hands.

"How long have I been standing here?" Sheldon asked him.

"Long enough," Leonard replied dismissively. "Are you ready to go?"

Sheldon set down the marker he had been holding, grabbed his bag, and nodded his head. As they walked down the stairs, Leonard spoke of something he found eventful but Sheldon didn't, so he didn't listen. He let his mind wonder, something he usually didn't do. He thought about what 'didn't happen.' Damn this pretending, he thought and looked over at Leonard. Could it be bothering him as much as it did Sheldon? Did he know that it was killing him, that he was biting his tongue so he didn't say something stupid?

Good Lord, Sheldon. Get a grip!

Leonard couldn't get it off his mind. It was like a really angry ghost, it was relentlessly pestering him all day. It was like a record stuck on repeat and he couldn't plug his ears or make it stop. But why? It was just one tiny, accidental, kiss. But it was sort of more than that. It was Leonard's first kiss with another guy, and he assumed it was Sheldon's too. Had Sheldon even kissed anyone before that? Usually people remembered their first kiss with someone really well, the way their lips tasted or if it was even a good kiss. But all Leonard remembered was the fact that it happened. He had been so tired, and so terribly unsuspecting that when it happened, his mind went blank. He did remember not knowing what was happening. He remembered standing there without a clue. But when he did realize, for some reason, he hadn't pulled away. He had waited for Sheldon to realize it too, then they pulled away together. Why had he waited?

Sheldon probably forgot about it already. That's how unimportant it was. That didn't make Leonard feel any better, though. Sheldon always forgot about his roommate, or so it seemed. Sheldon didn't even realize that Leonard was in the room earlier that day!

And now, when Leonard was supposed to be working, he was thinking about his roommate instead! Not that his work was really going anywhere, he wasn't doing any original research. It wasn't like he could get behind, he could just copy the results that were written in that other paper.

Speaking of experiments… Schrödinger's cat wasn't applicable to the kiss. Damn. You might ask, 'why isn't it applicable?' The answer, to Leonard, was quite simple. The kiss had been completely accidental, so neither person had expected anything. How could you know if the cat was alive when you didn't even know you were looking at a cat? And so, if it had been intentional, the results could be analyzed. Not now, though. Not when Leonard could hardly even remember it!

He glanced up at his clock. Oh, good. It's lunch time. He hoped that social interaction might help him get out of this stupid spell. This spell that all started with one little turn of the head.

"So, what's new?" Howard tried to start the conversation as everyone sat down. Sheldon bit his tongue again and thought about what Penny had said. He glanced over to his right where Leonard sat.

"Nothing…" Leonard said a bit squeamishly. Was he thinking of the same thing Sheldon was? Was he thinking about last night? These unanswered questions were driving him crazy. He had spent the entire morning thinking about it. He had copied all his previous work on his university whiteboard down onto six sticky notes and then wiped the board clean. He had locked the door so no one would walk in on him and he wrote new equations. He tried to understand why he couldn't think about anything or anyone else. He couldn't understand it. The beautiful mind of Dr. Sheldon Cooper could not understand this feeling. He didn't even know what it was.

He had no idea that the feeling was love. How could he, though? He had never experienced it before. He was so innocent, uncontaminated by the idea of love. It was all so new.

"Whuddya wanna do for dinner?" Leonard asked Sheldon as they walked to the car. "Howard's having dinner with Bernadette and Raj can't come over."

"Well, you know very well that it's Thai food night. And since it's just us we don't need to get takeout."

"What about Penny?" They climbed into the car.

"She's…busy." Sheldon decided not to tell Leonard that she had a date. It would just get his roommate in a pissy mood and he didn't want to deal with that.

"Alright… just you 'n me." This is not what I needed… Sheldon thought. He most definitely did not want to be alone with Leonard. He was afraid he'd say something stupid.

As they ate, Sheldon seemed to refuse to shut up. Which was interesting to Leonard, usually Sheldon only talked this much when he was nervous. Was he?

Leonard continued eating and pretended to listen to what Sheldon was talking about. It was something about a theory he had. Leonard got distracted by Sheldon's eyes again. They changed hue as they darted around. One second they were bright like a glacier, the next they dark like the color of the TARDIS from Doctor Who.

Leonard suddenly found himself wondering what it would be like to really look into those eyes. Sheldon hardly ever made direct eye contact. It was just something he didn't do. Sometimes this frustrated Leonard. It made him feel like any conversation they had wasn't important enough to the theoretical physicist. Not important enough… Was Leonard not important enough? He drove Sheldon to and from work everyday, he drove him to the comic book store, to paintball and to doctor appointments. He made sure to pick up the low sodium soy sauce and order his food correctly. And, more importantly than all the things he did for Sheldon, he was his best friend. How could he not be important enough? No, Leonard was definitely important enough.

Sheldon stopped speaking and looked right at Leonard. Straight into his eyes. Leonard was frozen in place. Something looked different about his eyes. Was it just that this was one of the few times he had looked directly at them? No, no, no. There really was something different about them.

They were slightly, just slightly, dilated. Dilation indicates attraction…

"Are you alright, Leonard?" he asked, not moving his eyes and inch, and not changing his tone of voice at all.

"Yeah. I'm fine. Are you?" he asked in response. He was, of course, referring to his new discovery. Not that the other man had any idea.

"I am fine, as well." Sheldon looked back down at his plate. It was nearly empty. He took a sip of his soda and Leonard tried to eat some more, but he wasn't hungry. Not after noticing a little glimmer of hope in the unromantic Sheldon Cooper.

A/N I do not know when this ff takes place, it's gonna have Bernadette in it, but not Amy. Also, Penny and Leonard are not together (if you didn't figure that out already)

This was originally going to be a oneshot, but now that I'm finished with this chapter, I see that is not going to happen. :P As some of you know, I'm usually a big 'ol Shenny shipper and I normally don't like Leonard, but when I thought about how funny it would be if these two accidentally kissed… well, I couldn't resist. There will be many more chapters to come, I hope you liked it! :) review if you like.

P.S. my apologies in advance for the long author's notes. I'm a bit of a rambler…
