Jess lifted her laptop. “I’m cool anywhere.”

Lisa tried the door, then pulled out her keys and unlocked it, immediately wincing as she turned back to Jess. “This okay? I forgot how messy he is. I never go in here.”

And… wow. David’s office was the upside-down version of River’s. Where River’s desk was bare but for his computer, David’s had the look of a desk found in the rubble post-hurricane. It was covered with printed-out data sheets, empty paper cups, wadded-up napkins, Post-its, and stacks of journal articles. His shelves were lined with a dusty and disorganized array of convention freebies: a Merck-branded stress ball, a Sanofi travel mug, a plastic DNA molecule from Genentech, a pile of branded pens.

But listen. River Nicolas Peña had just told her he loved her. Lisa could drop Jess off on Bourbon Street early on a Saturday morning and she’d be fine. “This is great.”

“We’ll come grab you when Aneesha is ready.” Lisa grinned before ducking out, closing the door behind her.

Staring at David’s desk, Jess wondered whether she should use her laptop on her actual lap, before figuring she could just carefully set it on top and not disturb the mayhem. While her computer booted up, Jess glanced around the sciencey detritus. Among the papers were sheets and sheets filled with hundreds of rows of data. An electrical current passed over her. Maybe that was a thread of why she and River were a Diamond Match—they were both deeply enthralled by numbers.

About halfway down a messy pile of papers, a corner of one stuck out. Jess’s eye caught on something written in the top left corner, and she carefully pulled free the thick binder-clipped cluster.

Client 144326.

Her blood turned carbonated as she registered what she was seeing. That was her. Jess’s data. And beneath her number was another: Client 000001.

River.

Below, in bold, was the information they’d heard a thousand times in the past month: Compatibility quotient: 98.

She’d never seen their raw scores before, but there was something oddly holy about holding the data in her hands.

Okay. I’ll see you in a bit. I love you. His words echoed in her mind.

Smiling, Jess scanned the rows and rows of numbers reverently. The client numbers and compatibility score were in the top left corner, and in the top right was the assay information: date, time, which DNADuo machine had run the assay, et cetera. Below that were about sixty rows of numbers, broken into three groups of columns, each three columns wide. Behind this sheet, there were pages and pages of solid numbers.

Jess got chills realizing she was currently holding the information on the roughly 3,500 genes for which she and River aligned. Was it really possible that their connection—their love—was encoded in their cells? Was she programmed from the day she was born to feel this happy—even when Jamie was leaving her over and over, when girls teased her on the soccer field for her drunk mother on the sidelines, when Alec stared mutely at the pregnancy test for a handful of minutes and finally said, “I’ve never wanted kids”? Of all the men Jess could connect with, was River her perfect fit all along?
