After tragically losing her first love, Penny begins to realise that sometimes your first love isn't your true love. That just because someone will always have a place in your heart, doesn't mean it can't be destined to belong to someone else.

TiMER AU. What if Leonard and Penny - and the rest of the world - were able to know at the moment they met their soulmate that he or she was the person they were meant to be with? It's sure to scare the commitment - phobic Penny. Leonard is sure to be overzealous. Primarily a Leonard/Penny story with an accelerated timeline, but there's some Shamy, Howard/Bernadette.

On an afternoon in late April 2010 Leonard left work to drive home alone. A day later his car was found abandoned by a river miles from Pasadena, its driver missing… Set after the Leonard and Penny breakup in S3. It will tell the story of Leonard's disappearance. DISCLAIMER: I do not own The Big Bang Theory.

One morning Leonard finds Penny having a seizure. Not far later she has another one and Penny is rushed into the emergency room After this follows months of tests, x rays, and more tests. And along the way a lump is found in her abdomen... could that have something to do with the seizure? Well. No matter what one thing is certain. Nothing will ever be the same... or will it?

Lives change after Leonard is critically injured.

Post S7/E14 The Convention Conundrum. Penny will do whatever it takes to get her nerds to the comic book convention. Rated M for later chapters. All main characters appear in later chapters. Penny and Leonard's characters are OC especially Penny.

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?

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.

"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')

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.

AU. All of our beloved characters are attending Pasadena High School together. Penny and Bernadette don't associate with the guys, that is until their new friend Amy brings the two social groups together.

Penny makes a mistake when returning home from an errand, and it could change her life forever. Warning

Leonard's taken because they think he has some classified information. They also have Penny and they're now threatening to "have some fun" with her. Something has to be done. Rating because of violence.

An ending; followed by some awful news.

A Leonard & Penny vacation one-shot. Beware! Hints of spoilers for late season 7 are contained

Set 30 years after The New York Revelation. Changes for Leonard and Penny

Sometimes you do things just because you love them. A little collection of one-shots from feels-inducing episodes.

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.

Leonard is leaving and while Penny is finding it hard to deal with, the impending change is bringing out some unexpected changes in Sheldon. How will Penny deal with being without Leonard, and how far is Sheldon willing to change in order to keep Amy? This is a L/P and S/A story. There will be some spoilers for season 6. Please read and let me know what you think! :)

The small group of friends goes on with their lives after the birth of the Hofstadter children. Unknown to each of them, there will be a paradigm shift in each of their lives. Contains standard parings L/P, S/A, H/B, R/A

Amy knows that she inserted herself in to Penny's life; that their "best friendship" is likely one-sided. She doesn't need Penny to prove herself. [Spoilers for The Locomotive Manipulation]

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.
