A/N: Here's Stacie's chapter. My geekiness might have gotten me carried away with the first parts…

Anyways, enjoy the Staubrey.

I'll post Aubrey's chapter later tonight.

And thanks for all the reviews and continuous support!

I don't own pitch perfect.

It's remarkable really.

How everything is made up of numbers.

How you can know everything there is to know in terms of digits.

Coordinates.

Simulations.

They're all about crunching the numbers.

Remarkable.

And how we're made up of chemicals that keep undergoing reactions in a certain way, with all the right conditions that experiments can't even perfectly replicate, keeping us alive.

They can come close as much as they want.

But you can't replicate the universe.

The tiny universe that is the mesh of DNA replicating, cells interacting, neurons firing ions, chemicals inducing sensations and reactions.

And the big universe, matter, earth, space, and apparently the fabrics of time and reality.

It's all so purely remarkable.

We are all specs of dust in comparison to the big universe.

It's like we're the molecules.

Like we're the DNA that carries its genetic component.

We – from our interactions, reactions, decisions – are what's keeping it alive.

In the same way that it sustains us.

What's even more remarkable?

How us tiny humans even find our right match.

Our perfect base pair.

The one that fits.

Stacie leaned on the back rest of her chair, pleased at finally completing her invention to help Beca find her way home when she almost jumped at the sound made by the glass doors of her main lab swishing open.

It was a little past midnight her staff and interns all resting in their warm homes. But Stacie's working overtime. Their world had slowed down on its rate of colliding with the Beca's own, and the medication she's given the DJ is helping to make sure the memories of two Beca's don't completely converged.

Still, work overtime she shall, because she won't be able to breathe easy until everything is as it should be. There was lot at stake.

And Stacie's was sure too that none of her lab workers understood just how much was at stake, to them she's just babbling on about the significance of their studies as usual.

So she wasn't expecting anyone else to be there at all.

"Hey you, look what I brought." Aubrey said with a smile on her face as she walked around the work bench that separated her from Stacie and placed the box of assorted pastries from a nearby patisserie and two cups of coffee.

"And what brings you here Bree?" Stacie said with a wide grin on her face as her wife leaned down and kissed her first on her forehead, then on her right cheek, and finally on her lips.

"Nothing, I just missed you." Aubrey answered truthfully as she sat down on Stacie's lap and the two settled in a comfortable position, Stacie wrapping her arms securely around Aubrey.

"What's on your mind, come on, tell me." Stacie then said as Aubrey reached for the box and took a bite of a cookie.

Aubrey sighed. "Chloe came by to see me."

Stacie hummed, placing her chin on Aubrey's shoulder. "And?"

"She's in love with Beca. I think she never stopped loving her."

"I figured."

"You figured?"

"Yeah, look, we've been assessing all of the world's Beca visited. She'd tell us what the world was like, you know, her alternate reality, and everything she witnessed happening. Everything she experienced and felt."

"Stace, I already know this."

"In every world, she falls in love with Chloe, and Chloe falls in love with her. Well other than the Batman alternate universe, she woke up from there before meeting Chloe."

"There was a Batman reality? Why didn't I hear about this before?"

"That's what you got from what I just said?"

"Sorry. But you're telling me all about this later."

"Nope, doctor-patient confidentiality."

"Fine, I'll torture it out of Beca later." Aubrey commented, and Stacie could tell she was only half joking.

The other half was deathly serious.

"Anyways. So you're telling me your hypothesis panned out. In every world, every universe, no matter what circumstance, they're meant to be together."

"Yep."

"Like there's this strong unstoppable force pulling them together. Something divine in nature if not completely beyond the realms of our, your, scientific understanding."

"You know, I believe that I saw something once that scientifically explained soulmates somewhere on the internet."

"I'm being serious Stace."

"Fine. Then yes."

By the Aubrey untangled Stacie's arms around her only so that she could intertwine their hands together before wrapping them around her waist once again. "And us?" the blonde asked.

"Ah, so that's what you're interested in." Stacie commented with an even wider grin than before. "Apparently even in the Batman-verse we were together so I'd say we're meant to be too." She answered before giving Aubrey a quick peck on the cheeks.

"Okay, then that makes me feel better. Chloe will sort herself out, choose Beca, and they'll live happily ever after. And we're going to give them a huge nudge in the right direction."

"Are you still hell-bent on your little covert operation with the Bellas?"

"Of course we are." Aubrey answered back, emphasizing on the 'we' part of the statement. After all, they were all in this. "How are you holding up on the scientific end of things?"

"I'm good. It's really up to Beca and Chloe. Chance too."

"Who's Chance?"

"No, I meant chance as in possibility, likeliness, serendipity, you know. Fate." Stacie answered with a chuckle.

"What? You had an intern named Lucky once. Then another named Serenity. And let's not forget Dreamy, who I still think is a long lost fairy tale character." Aubrey answered, a smile taking over her face. "But seriously, fate, huh?"

"Yeah. To be honest, most experiments are successful by chance. You don't know what will happen until it happens, and sometimes you try fifty different things, changing one variable at a time to see how it affects everything else, until you just happily stumble upon that magic formula that works. I know it sounds so unscientific, but if it works, it works."

"Stace, what will happen if Beca fails? If our earth converges with hers?"

"Our realities will mix, become one. My hypothesis is some aspects of our reality will transfer over and some aspects of theirs will remain."

"And us? What if our memories mix? What if some things get erased?"

Stacie looked properly at Aubrey, she could see it in her wife's searching eyes the fear of the uncertainty that might take hold of what they've known all their lives. The uncertain Fate of their memories and everything they hold sacred.

And truth be told, Stacie was scared too.

She doesn't have an answer to that question.

Not even a hypothesis.

As much as she wants to have one.

She's only holding onto what she knew was true.

She loves Aubrey.

And she knows she'll always love her.

Come what may.

"Bree, it doesn't matter. Whatever happens, we'll always end up here, together in each other's arms, okay? So don't worry. I'll love you in whatever world or reality we get thrown into. We'll find our way to be together."

Aubrey stole a quick kiss on Stacie's cheek before taking a deep breath and releasing it with a smile on her face before she reached out for a macaron handing it to Stacie.

And what was Stacie to do but dutifully took a bite out of it from Aubrey's hands.

"Okay. I trust your instincts here Stace."

Stacie simply smiled back.

The unknown always freaked her out a little.

Especially the ones without an answer.

But her brain can only process too much information at once.

And she knew for a fact too.

That somethings are simply left to chance.

To Fate.

Or to whatever divine force it was that designed the universe.

Whether it was that designed it from the big one to the tiny one, or in the reverse direction, reflecting its complexity at each stage.

She can only do so much to comprehend and contribute to the understanding of this complexity.

Having the right conditions at the right time.

And now that she's done her part.

All she could do is be in awe of the ever expanding universe.

Watch as things unfold.

And hope she was at least partially right with all her educated guesses.

For all the Bellas.

For Chloe.

For the Beca's of both realities.

And most importantly, for Aubrey.
