She called Cosima later to apologize as she sat on the couch in Felix's apartment. Whatever else she might have wanted from Cosima, or rather, whatever else she wanted Cosima to want from her, it wasn't worth ruining their friendship over. Cosima had waved it off in her typical happy go lucky fashion, blaming the dispute on a bout of nerves for one of her upcoming term papers.

"And besides," Cosima had said around what was probably a blunt between her lips, "Delphine and I are taking it slow. I mean, I don't even know if she swings that way, man. We're just friends. Just hanging out, you know? Illegal science experiment and monitor, best buds, just the way it should be."

Sarah let out a relieved laugh, "Yeah, totally normal. Just the average day in the life of a clone, right?"

Cosima chuckled, giving an affirmative hum. Sarah heard the faint pop as Cosima took a deep pull from the blunt.

"So," Sarah said, not wanting the conversation to end quite yet. "How'd your paper turn out? What was it on? Biological... nucleosis or something, right?"

Cosima's raspy laugh on the other end made her grin like an idiot. She bit her lip, trying to hide it even though no one was around to see.

"You know, Sarah, I've never heard about biological nucleosis before, but maybe you could teach me a little more on the subject."

"Very funny, Cos."

"I know, I'm like the funniest person I know. No, it was actually about the characterization of an aminoglycoside antibiotic-resistant methyltransferase protein from Pyrococcus furiosus in relation to phylogenetic reconstructions."

Sarah was legitimately awestruck for a brief moment. "Okay. Ah, that sounds bloody..."

"Fascinating?" Cosima prompted.

"Well, I was gonna go with terrifying, but yeah, sure, whatever floats your boat, Cos."

The conversation flowed easily between them and Sarah found her cheeks and sides hurting from the amount of laughing she had done nearly the entire time. Cosima had just finished telling her a story of one of her professors who had actually fallen asleep in the middle of his own lecture. Sarah was sure that Cosima could tell a story about moss growing and make it interesting. and more often than not, her particular brand of wit and sarcasm had Sarah in stitches. She sighed deeply, her chuckles fading off as she wiped her eyes briefly.

"Oh, shite, I'm crying, Cos."

"This is my life, Sarah. These are the idiots I deal with on the daily. It's unreal. You should come out here and see for yourself, you'd love it."

"Yeah," Sarah said, folding her arm across her stomach. "Maybe I should."

There was an easy pause and she heard Cosima sigh contentedly on the other end. Sarah closed her eyes for a moment, just listening to the other woman breathing. Emotion welled up out of nowhere, making Sarah's throat tight.

"I miss you, Cos."

There was a surprised silence on the other end and Sarah's gut clenched, all of her instincts suddenly and immediately telling her what a bloody idiot she was for saying something like that out loud. She was just about to take it back, apologize for being so forward, when Cosima's voice drifted into her ear.

"I miss you, too, Sarah. I really do."

Sarah bit her bottom lip hard, trying not to let her voice give away the fact that she was bloody beaming over that.

"Alright. Well, I should probably go. Fee is gonna be home soon and I promised I'd get the trash taken out before he got back."

"Sure, sure," Cosima murmured, and Sarah was almost positive she could hear a grin in her voice. "I get it, duty calls. Go pay your dues."

"I'll talk to you later, yeah?"

"Yeah, of course."

"Bye, Cos."

"Bye, Sarah."

The line went dead and Sarah tossed her forearm across her eyes, blowing out a huge gust of air just before allowing a full fledged smile to break its way across her face. She couldn't have known, but several hundred miles away, a clone with dreadlocks and Cleopatra eyeliner was laying face-up on her bed doing the exact same thing.
