An alternate universe on how Leonard and Penny met and the development of their relationship. I do not own TBBT characters.

This is an alternate story line on how Leonard and Penny met and the development of their relationship.

This is an alternate storyline starting from Season 6 episode 2 – "The Decoupling Fluctuation". In the series, instead of breaking up with Leonard, Penny sleeps with him and continued to date him. This storyline is the opposite of that.

An alternate story line starting at the beginning of Season 4.

In a world of deceit, Penny is down on her luck and is forced to be a prostitute for her pimp Kurt. But when a small bespectacled man hires her for an unusual job, her world changes. Rated M for violence. - Chapter 9 up.

This story takes place right after Leonard decided not to go through with being a surrogate father to Zack and Marissa's child.

This is my sequel to Continuation of Season 12: Lenny. First two chapters are already posted in the first story but are here in this story with some little tweeks. My take if we had a season 13 and based on Leonard and Penny as the await Baby Hofstadter. Chapter 48 is up and Lenny Love.

This is a little story, I have been working on since Christmas 2014 and I wanted to submit it while the holiday is still fresh in people's mind. It is AU a different beginning for Leonard and Penny. It is rated M for mostly for language.

Everything has its corollaries. Everything evolves. So does our famous "gang". This story follows the gang from 2029 on, as it grows and evolves through life's challenges. Canon couples, Raj/OC. Multiple OCs. AU to season 12. Includes everyone, to different extents. Sequel to "The Corollary Theory: The Celebration Aberration" but can be read without having read it.

Sheldon commits an unthinkable breach of trust and Leonard is through with him.

This originally was just a one shot, I had a story on my mind. I never liked episode 3.19, 'The Wheaton Recurrance', so I added a new ending. Well now I decided to use the episodes following 3.19 to show how they could have gotten back together. Each chaper will be it's own story.

A series of Leonard and Penny oneshots from different parts of the series. Lemon / Smut

Why did he have to leave a rose under her windshield? Why was she so mad about it? Some unresolved feelings and insecurities arise due to Leonard's unprompted romance, and Penny doesn't know how to deal with them. Got the idea from 9x02 so slight spoilers! One-shot.

It's Valentine's Day.

Penny had always loved New Year's Eve... but something had changed that for her. Leonard wanted to put some magic back in the Holiday for his wife.

What if Leonard and Penny never met because Leonard didn't move into 4A. Would Spiritual Connections be a factor. I do not own any of the characters.

Visiting home after her break-up with Kurt, Penny finds that the Nebraskan nightlife was incredibly generous to her on her first night out as a single woman. The only problem is, alcohol-induced memory loss is taking its toll and she can't quite remember one very important detail: his name.

A different beginning with a more confident Leonard who refuses to back down to Kurt when asked to retrieve a certain girl's television. How will things proceed from this altered beginning?

Leonard and Penny want to move out, Sheldon, of course, objects. Mostly Lenny, with some Sheldon and Amy, and the rest of the gang in a later chapter.

An alternate take on the "Penny and Leonard meet in a bar before the Pilot" concept. With thanks and credit to son-goku5. Rated M for adult content (specifically Chapters 2 and 6).

Sequel to The Situation Diffusion. After almost two difficult, challenging, career-altering years apart, Leonard and Penny are back together and ready to return home for their fresh start.

This is my first fanfiction and this prompt seemed like a good way to start.

Leonard meets a beautiful model

"It's just that you haven't turned the page for like... nearly two hours." Leonard offers a clueless Penny some help with studying, and they learn that the lines between cheerleader and nerd aren't necessarily parallel - in fact, with some work, they can form a neatly balanced equation. (That was cheesy, this is AU, a prequel-sequel to 'The 8 Simple Rules Paradigm')

This is a sequel to "The Fidelity Crisis". Follows from a remark made by KC-S in an interview about how she saw preparing for Penny and Leonard's Wedding might go. L/P as well as standard cannon pairings. Pure Fluff

Penny's Valentine's Day is ruined when her boyfriend isn't exactly who she thought he was. Lenny story!

Sheldon's reorganization of Penny's closet leads to Leonard and Penny discussing previous relationships and commitment issues. Set at and after the tag of 6x19 through the end of season 6. Possible reasoning for Leonard and, mostly, Penny's actions since late season 3. Rated T to M for random sexual references.

Short Lenny one shots based off a post I found on Instagram. Hope you enjoy :)

What if story. What if Penny actually became an actress like her original plan only a year or two after getting to California. Penny never moves to 2311 Los Robles, Pasadena, but things still have a way of happening.

Just after The Occupation Recalibration. Penny decides she needs to put all her efforts into seeing if she can make it as an actress. Leonard tries his best to support her efforts. Can long distance relationships work for the two of them? Mainly L/P but the others will appear as necessary.

Follow up to The Playtime Experience (highly recommended to read that first); Leonard needs repeatable results in order to come to a decision on which outfit is the sexiest. Neither of the participants has any objection to repeating those three nights. Rated M for a reason.

This story occurs after episode 6.08. Penny has job, career, and self worth problems, plus she needs to consider where her and Leonards relationsship is going. My first fanfiction.

Two years ago Penny's life changed forever when she landed her dream acting job. Now at the mercy of her manipulative and violent husband the dream has turned into a living nightmare….a nightmare in which Leonard may pay the ultimate price. This story begins in the present and will then flash back over the preceding two years. Warning rated T for domestic violence/language.

Some things don't conclude the way you expect them to, and Leonard and Penny learned this the hard way - but they also learn that 'dealing with it' doesn't mean something is dealt with, and time neither heals wounds nor erases feelings. Strays in a different direction from a canon plot which will be revealed further along.

Penny's a successful actress. Her new movie is filmed partly on location at CalTech, where a short bespectacled physicist is assigned to help out with all the scientific details, including helping her pronounce all the "techno mumbo jumbo". Totally AU.

What if Penny never moved across from Leonard, would he meet her.

Some bedroom playtime for our favorite couple. Warning: M-rated, mature readers only.

A little AU fic, in which Wyatt has eight simple rules for dating his daughter. Based on the rules of '8 Simple Rules'.

Sequel to The Parental Ambition. Picks up four years after Savannah's birth, eight months into Penny's second pregnancy, and about a year into the life span of Gilda's new board. Now rated M for "non-explicit suggestive adult themes."

Penny is attacked in the worst of ways, and Leonard is determined to help her get better. She was a pulchritudinous wreckage, of which he was determined to salvage. 'M' for a reason.

Takes place five years after The Decoupling Fluctuation (Episode 2, Season 6, aired Oct. 4, 2012)

AU fic. Leonard and Penny are in the same high school together. They just haven't met yet.

In this arc, Penny is the victim of a home invasion. She manages to inflict nasty injuries on the bad guys. This is a bit darker than the usual for BBT, but I am so intrigued by the Penny character and wanted to explore how she might respond if something scary happened. She is so strong. You go, girl. I have put my wife and myself in one of the chapters. See if you can find us.

Everyone hopes for their own fairytale ending, but the journey to 'Happy Ever After' is never an easy one to make. This story contains love, heartbreak, loss and tragedy. Brace yourselves, this will be a bumpy ride! The M rating is mainly for the adult themes and language than anything overly explicit. Please read and review. My first go at angst, lets hope it goes well!

This story follows Leonard as he makes a decision that will change his life completely, one way or another.

Leonard and Penny have both been left dateless for their friends wedding. Can this be enough to bring them closer together? Sorry for the not great summary, more will be explained inside. This is mainly a lenny story, but all characters will be included in the fic. Please read, review and hopefully enjoy :)

Set after Raj interrupts Leonard and Penny whilst they're in bed in the Love Car Displacement episode. Leonard is still in love with Penny, but does she feel the same way? Lenny story.
