Cosima and Delphine reunite at the Rabbit Hole. Just slide this in near the end of season 5.

Cosima Niehaus puts her wish out into the universe - after all it can't hurt to want something intentionally and see what comes back. Delphine Cormier shows up in the university lab one day and she thinks, maybe, just maybe she's getting what she wished for in a way. There's just one little problem...

1920s AU. Delphine catches sight of Cosima one night, believing it will be nothing but a brief fantasy she chooses instead to commit her likeness into fiction. A couple years later, Cosima mysteriously reappears, and choices must be made. Trying to have it both ways may destroy them both.

Cosima and Delphine set off on a roadtrip shortly after the fall of Neolution.

Summary: Like my Immortal Beloved and Sheldon Swifties bits in my Buffyverse and Sheldonverse, these are fragments and short bits, some longer…Just to fiddle with ideas, possibly forming longer tales later. Note-There are always these minor consequences to any great advances in Science.

Not sure if it's a one shot or longer. Cosima tries to help Delphine overcome nightmares.

Delphine Cormier resides with her family in Paris, France. The older couple who rent the downstairs apartment from them host international students for language exchange programs. When Cosima Niehaus arrives one day, Delphine anticipates more of the same. She gets far more than she bargained for.

Cosima Niehaus gets very bored in quaratine but at least she has an interesting neighbour. And a possible solution.

When a glance at a stranger in a bar turns into a planted seed in her head, Delphine can't stop returning to see her. Cosima is taken with the mysterious woman right away. A near cruel game of cat and mouse begins, complicated further by a husband, an audit, an amateur band, and a two-way obsession. Rated M for language and adult themes

Ms. S gathers a group of misfits and gives them a new reason to wake up for another day. The fact that said reason is less than legal is not but a minor detail. While her business has been thriving for the last decade, a new competitor is about to make the group run for their money.

Several years post-series, Cosima and Delphine rehash an uncomfortable conversation.

Roisin Vaughn, who is estranged from her family. She moved away when she was sixteen after getting emancipated. What happens when she returns home sixteen years later after her children get kidnapped? What if she's in danger and needs the help of her family? Will Sarah and Felix forgive their big sister for abandoning them? How will she react to finding Sarah's a clone? (S2 Ep.4)

AU. A story in two times. Present day: None of them were expecting this, not this seemingly instant bond between two elderly strangers, or the story that they had to tell. That they have met before, bringing a drama like no other back to life. 1952: Delphine Cormier and Cosima Niehaus meet for the first time, and become so close, that it threatens to tear their lives apart.

If you had the chance to go back and change something that affected you badly, Would you? Should you? Alison has a chance to do just that, but! There are always consequences.

The stars circled above them close enough to touch, yet Delphine's head remained lolled to the side; eyes glued to Cosima. Oui, she thought, blinking slowly at the moon reflecting off of the girl's glasses. Oui, I could lay here all summer. Je pourrais rester ici pour toujours.

Cosima knows Delphine is bait, deep down, she cannot really forget. But she takes the lure.

"Cosima is trying to be Sarah in Orphan Black but Delphine doesn't buy it (but she plays along because she likes seeing her in Sarah's leather jacket" Reviewer only

What happens when Emma finds out about Sarah's clones? And if Emma and Sarah are true sisters, where did they come from? / Focus on season one family relationships, especially b/w S & kids.

There are many things Delphine would undo, but she can't, because life is not a Cher song. Cosima/Delphine. AU. Femslash. Ficlet.

Twenty years ago the World changed and while some struggle to adjust to the new reality other muscle their way against the new world order.

(Vampire AU)

Sarah discovers why Helena's bleached hair hasn't grown out after all those years. Helena also discovers a secret of hers.

Delphine has been guilty of some mild stalking. It's not her fault, really... It's the bartender that's entirely too adorable. A Cophine Christmas Special (with little mention of the season... oops). Really just an excuse for some fluff and a bit of smut.

Cosima never made it home from the island. For three years Delphine and her sisters thought she was dead. What happens when she turns up on their doorstep.

Cosima has always put her family first; however, when a mysterious illness begins eating away at her body, she turns to the only person outside of her pack that she can trust.

Strictly and utterly for fun. Imagining our favorite seestras as Captains of the Federation flagship.
