By week two, Amerigo had resorted to colored ribbons tied around their right ankles. Gold for Electra. Blue for Celeste.

Without them, he genuinely couldn’t tell them apart—same white hair, same chocolate eyes, same tiny features, same expressions. They even cried in the same key, their sounds overlapping until he couldn’t distinguish who needed what.

Alex found it hilarious when he came to check on them. “You know most parents can tell their twins apart, right?”

“Most parents have twins that are actually different people,” Amerigo shot back without thinking, then froze. “I mean—”

But the joke landed wrong. Because something in the way they synchronized everything—their sleep cycles, their hunger, their cries—wasn’t normal even for twins.

Even this early, there were signs.

At six months, Amerigo fed them in high chairs side by side, trying to introduce solid foods per the developmental schedule Williams had given him.

He gave Electra a spoonful of mashed peas. Her face scrunched up in disgust, her mouth puckering like she’d tasted poison.

And Celeste, on the other side of the high chair divider, made the exact same expression—without having been offered any food yet.

Amerigo froze, spoon halfway to Celeste’s mouth.

Coincidence, he told himself. Just a coincidence.

He tried again, this time surprising Electra with the spoon while she was distracted. She startled, eyes going wide.

Celeste startled, too. Same timing, same wide eyes, same tiny gasp.

“What in the…” He looked between them. Both stared at him with identical expressions of baby confusion and growing wariness. “Okay. That’s weird.”

But he didn’t tell anyone. Not yet. Because what would he say? I think my daughters might be sharing experiences somehow? It sounded insane.

He filed it away in his mind with all the other oddities he’d noticed, telling himself it was just the strangeness of having twins, of being a new parent, of trying to navigate fatherhood while drowning in grief.

When they were two, Amerigo stood in the bathroom doorway, watching in confusion. Celeste, now wearing star-shaped gold earrings, had been playing in the living room. Electra, with amber earrings, had announced softly, “Potty time!” and trotted off to the bathroom.

He’d followed Electra, ready to help. But before he got there, Celeste had abandoned her toys and was already walking toward the bathroom too—without a word being spoken, without any signal he could detect.

They both used their respective toilets, perfectly synchronized, and then both washed their hands, chattering to him but never to each other.

“Good job, girls!” he said, trying to sound normal.

But inside, his scientist’s brain was cataloging: No verbal communication. No visible signals. Perfect synchronization. How?

She was three years old. They were in the hydroponics bay with Dee, supposedly learning about plants. But Dee had asked, “Celeste, can you and your sister water those tomatoes?”
Both bodies stopped moving. Turned. Fixed Dee with identical expressions of patient exasperation.

“I’m not two people,” she said, voices overlapping. “I’m just me.”
Dee glanced at Amerigo, uncertain. He shrugged and smiled. “Sorry, sweetie. Can you water the tomatoes?”

“Yes, Daddy.” And she did—one body holding the watering can, the other guiding it, moving together like a choreographed dance.

Afterward, Dee pulled him aside. “Amerigo… did you notice they said ‘I’m,’ not ‘we’re’?”
He had. But he’d dismissed it as linguistic confusion. Three-year-olds made grammar mistakes all the time.

Didn’t they?

By five, teachers noted they never spoke between themselves, yet moved in perfect unison—drawing identical pictures, solving puzzles as if one brain drove both bodies. At six, Amerigo began to wonder.

Alex and Dee saw their uniqueness, too. Alex, still carrying the weight of losing Jenni, adored them. He once gave them a broken comms unit, expecting a mess. Instead, one body dismantled it while the other sketched a fix, their movements eerily coordinated. “They’re brilliant,” Alex told Amerigo, shaking his head. Dee, gentler, braided their fragile, white hair in the hydroponics bay, sharing stories of Earth. Once, she watched one body watering plants while the other drew their leaves, perfectly matched. “They feel the world so deeply,” Dee said softly.

Now, Amerigo was seeing old memories in a new light. Celectra lived her single mind across two bodies like a birthright. Even now, resting and still. But Amerigo’s mind flashed back to her everyday life: the controlled chaos of her unique play. She was the unofficial ruler of the Utopis station’s sloping corridors. She didn’t just walk—she flowed. On the way to music, karate, or dance class, one body would run ahead, darting behind an air scrubber, while the other would pivot on a dime, laughing as it chased its own reflection.

He remembered the time she reprogrammed the reclamatics to follow her like ducklings last year when she was 6. One body stood beside a maintenance panel, fingers flying over the interface like she was tickling it into submission. Amerigo had thought it was a game. A prank. A coincidence. But now he saw it: the choreography. One body distracted the automated cleaning bots—twirling, skipping, tossing a crumpled piece of paper like bait. The reclamatics, programmed to chase debris, followed her in a neat little line. Meanwhile, her other body rerouted their behavior protocols, assigning her own biosignature as their new “target object.” She didn’t need to speak. Didn’t need to signal. She just knew what her other self was doing. And when the reclamatics began trailing behind her like obedient ducklings, both bodies giggled in perfect unison. Amerigo had laughed, too, back then. But now, he relived it with awe.

Another time, Celectra had convinced Aunt Dee to teach her how to make real pancakes. In the Cruiz’s kitchen, one body smoothly beat the batter with a whisk while the other, at the counter’s edge, delicately portioned and folded in melted butter—a seamless, yet messy, division of labor resulting in perfectly proportioned ingredients in the mix and two sets of small, flour-dusted footprints leading away from the crime scene.

They moved like two ends of the same magnificent piece of string, never crossing, always connected, owning the space as if the entire station were their private playroom

Just yesterday, though it felt like a lifetime, Amerigo had watched her solve a calculus problem that Utara had given her as a “challenge”—high school-level mathematics. Problems he himself struggled with.

One body wrote the equations in smooth, confident strokes. The other sketched a visual proof, translating abstract numbers into geometric shapes. Both worked simultaneously on different aspects of the same problem, never consulting, never checking with each other, never even glancing between bodies.

When she finished, she’d looked up at him with both faces, grinning. “That was fun! Can I have another?”

He’d stared at the completed work, his heart pounding with a mixture of pride and something else—something like fear, or awe, or both.

“Girls, when you do that—when both of you are working on the same problem—what does it feel like?”

Both heads tilted in perfect synchronization, considering. The gesture was so precisely mirrored it made his skin prickle.

“It feels like… me thinking,” she said slowly, as if searching for words to describe something that should be obvious. “Just me. With extra hands.” A pause, those chocolate eyes—shaped like Jenni’s eyes, he thought with a pang—studying him with concern. “Why, Daddy? Does it feel different when you think?”

And that’s when he had called Alex for the appointment. Because that simple question had crystallized everything he’d been noticing, everything he’d been too afraid to name.

Does it feel different when you think?

She genuinely didn’t understand that other people experienced consciousness differently. To her, having two brains, two bodies, and two sets of hands—it was just how thinking felt. How being alive felt.

How being herself felt.

***

Now, in the present moment, with her four little feet warm in his hands and her dual breathing steady and synchronized, Amerigo understood.

The potty training. The synchronized reactions to food. The way she never argued with “herself.” The reclamatic incident. The calculus. All of it.

It wasn’t coincidence or trained behavior or exceptional twin intuition.

It was Celectra being Celectra. One mind. One consciousness. One extraordinary person who happened to have two bodies, the way some people happen to have blue eyes or perfect pitch.

The radiation that had killed Jenni hadn’t destroyed their daughters. It had transformed them. Created something new. Something that had never existed before in all of human history.

And Jenni had known. Had felt it even before they were born. They’re special. They’re connected. Don’t let anyone make them feel wrong for it.

“Daddy?” Both voices spoke at once, soft with concern. “Are you okay? You’re thinking really loud.”

He smiled, despite the tears threatening to fall, and reached over to brush a strand of white hair from one of her faces. “Just remembering your mommy. And thinking about how proud she’d be of you.”

Both bodies shifted, setting down her holopads, both sets of eyes focusing on him with that unnerving, perfect attention. “Tell me something about her. Something you haven’t told me before.”

He thought for a moment, still absently rubbing her feet, feeling the warmth of her—singular her—spread across the sofa. There were so many memories. So many stories.

“She used to sing in the shower,” he said finally. “Terribly. Off-key. Songs from Earth that nobody else in the system had even heard of. And she’d make up half the words when she forgot them.”

Both faces lit up with delight. “Like what?”

“There was this old song called ‘Twinkle Twinkle Little Star’—except she’d sing it ‘Sparkle sparkle little sun, burning bright when day is done.’” He smiled at the memory and could almost hear her voice echoing off the shower walls. “She said the original didn’t make sense because stars burn during the day too; we just can’t see them.”

Both bodies giggled—a sound of pure joy that seemed to fill the room. “That does make more sense!”

“She always made sense. Even when she was being silly.” He squeezed her feet gently, grounding himself in the physical reality of her. “You’re like her that way. Brilliant and joyful and… unique. In the best possible way.”

A pause. Her bodies had gone still, both sets of eyes distant.

“Daddy?”

“Yes, sweetheart?”

“Do you think she knew? Before she… before she left? That I’d be like this?”

The question hit him like a physical blow. He thought about Jenni’s last words, spoken with such urgency: They’re special. I felt it. They’re connected somehow.

“Yeah,” he whispered, voice thick. “I think she knew. I think she felt you—really felt you, the real you—before anyone else did. Long before I did.”

Both bodies moved then, abandoning their positions on the sofa arms to curl up against him, four arms wrapping around his torso, two heads finding the hollows of his shoulders.

“I wish I could have met her,” Celectra said softly. “I wish I could remember her.”

“You do, in a way.” Amerigo held her—held her, singular, miraculous her—and let himself finally grieve and celebrate at once. “Every time you figure out a puzzle or ask a brilliant question or refuse to accept easy answers. Every time you see beauty in strange places. That’s all her.”

He paused, then added, “And every time you use your uniqueness as a strength instead of hiding it—that’s you honoring what she gave up everything for. You existing, just as you are, is what she wanted most.”

They sat like that for a long time, father and daughter, wrapped in memory and love and the weight of a legacy neither had asked for but both would carry forward.

Outside the porthole in the floor, Ares spun past in shades of rust and shadow—the same moon Jenni had surveyed, had mapped, and had helped transform into humanity’s new frontier.

Somewhere on that moon, in labs and homes and schools, the colony was growing, thriving, and building the world Jenni had dreamed of.

And here, on this station, her daughter—singular, extraordinary, impossible—was growing too.

“I love you, Celectra,” Amerigo whispered into her white hair. “Both of you. All of you. Every part of you.”

“I love you too, Daddy,” she replied, her voices harmonizing perfectly. “All of me loves all of you.”

And for the first time since Jenni’s death, Amerigo felt something like peace.
