Old Joe's prosthetic arm clicked when he was nervous. It had been doing that since the Great Deluge, when he'd lost his left arm to a rusting oil rig collapse on Platform 14. The replacement — a jury-rigged monstrosity of salvaged hydraulic parts and car battery wiring — clicked with every tendon-tension in his remaining right arm. It was a betrayal his body had made peace with, but his mind had never forgiven it.

The click had been going non-stop for the past twenty minutes.

"Easy, little buddy," Old Joe muttered, kneeling on the deck of Platform 7 with Little Blue's head in his lap. The Abyss Beast's iridescent blue scales caught the ambient light from the platform's flickering sodium lamps, creating patterns that looked almost like art if you squinted hard enough and weren't thinking about the fact that the creature was a genetic abomination.

Little Blue tolerated the examination with the patient resignation of a creature that had learned humans were generally harmless, occasionally helpful, and usually annoying. Its large, dark eyes — positioned on either side of a head that was roughly the shape of a whale's but slightly flatter, slightly wider, with too many teeth — watched Old Joe work with an expression that might have been boredom if boredom could be expressed by a creature that wasn't technically any single species.

The neural chip was almost free.

Old Joe's hands — one flesh, one metal — moved with the practiced precision of forty-seven years of mechanical work. The chip had been embedded in Little Blue's brain tissue during the old world, implanted by military surgeons who had apparently decided that enhancing animal intelligence was a good use of their talents. Old Joe had found the chip by accident while diving for circuit boards near the old military testing grounds. He'd pulled it free, cleaned it off, and plugged it into his game controller.

It had worked the first time. That was the problem with old-world technology — it worked too well.

"Got you," Old Joe said, and the chip came free with a wet click. Little Blue flinched, creating a small wave that splashed across the platform deck and dampened the rust that Old Joe had spent the morning scraping.

The mechanic swore quietly and got a towel.

By the time Old Joe had installed the chip in his remote pilot pod — a device that looked like a scuba helmet connected to a car battery connected to a repurposed gaming console via about forty feet of questionable wiring — the Cartel was waiting for him on the platform's main deck.

They didn't have a leader, the Cartel. Decisions were made by consensus, which meant that whenever someone needed to make a decision, seven different people would talk about it for three hours and then somehow arrive at the same conclusion that the first person had reached. It was inefficient. It was also, Old Joe had to admit, more fair than most forms of governance he'd seen in the wasteland.

"We need to move the chips," said Mara, the Cartel's de facto voice on logistics. She was a tall woman with a face like a knife and a habit of standing too close when she talked. "Purification Alliance has the new scanning towers online. Traditional routes are burned."

Old Joe scratched the back of his neck with his flesh hand. "I got an idea."

He showed them the pod. He showed them how it connected to the neural chip. He showed them how Little Blue had responded to the first test run — swimming in the exact direction Old Joe commanded, with the precision of a guided missile.

Mara stared at Little Blue for a long time. The Abyss Beast stared back, water dripping from its teeth.

"It's ugly," Mara said finally.

"It works," Old Joe said.

"It's an abomination," said another Cartel member, a thin man named Silas who had survived the Deluge by learning to eat things that should not have been edible.

"It works," Old Joe repeated. "Four tons of purified water chips. One trip. The Purification Alliance scanners can't detect biological signatures the way they detect chemical signatures. We go through the open sea, we come out the other side, we deliver. Everyone gets water. Everyone lives."

They agreed, as they always did, after three hours of talking.

The first trip was a triumph. Little Blue swallowed the pod with the data, swam due east for six hours through water that was more salt than liquid, and delivered the chips to the sky-palisade on Mount Kilimanjara's peak. The Cartel members there wept when they received the water — not dramatically, but the quiet weeping of people who had gone months without clean H2O and suddenly had a crate full of it.

The second trip went similarly. Old Joe developed a rhythm: wake up, scrape rust, feed Little Blue, run the pod diagnostic, swim, deliver, repeat. The mechanic began to notice things about Little Blue that he hadn't noticed before.

The Abyss Beast was changing.

Not physically — its body remained the same grotesquely beautiful hybrid of whale and shark and something else. But its BEHAVIOR was shifting. Little Blue began to respond to commands with delays, as if it was considering the request rather than simply obeying. It began to swim patterns that didn't match any route Old Joe had programmed. It began to SING.

The song was the most disturbing part.

Old Joe wasn't a musician. He couldn't tell you if a song was in key or out of key or whatever musicians talked about. But he could tell you that Little Blue's song was unlike anything he'd ever heard — a garbled mix of biological vocalization and digital data transmission that sounded like a radio broadcast happening inside a whale's throat. Sometimes it was beautiful. Sometimes it was just wrong. Sometimes it was both at the same time, and that was the worst.

"What are you?" Old Joe whispered one night, sitting on the platform deck with his prosthetic arm clicked into a resting position, listening to Little Blue sing in the dark water below.

Little Blue's song paused. Then it continued, with a new note added to the pattern — a note that Old Joe's mechanical arm responded to. The click in the prosthetic changed frequency, synchronizing with the song.

Old Joe stared at his arm. The click was a coincidence. It had to be. The hydraulic tension in the arm was random. It couldn't possibly be —

"It's talking to me," he said quietly. And he didn't know whether to be thrilled or terrified.

The third trip was the last successful one. Old Joe delivered the chips, collected the Cartel's payment (purified salt, old-world antibiotics, and a working solar panel that he installed on Platform 7 that same evening), and began the return journey.

Halfway through, the sensors picked it up.

The Natural Guardians. They'd found the smuggling route.

Old Joe didn't have time to think. He activated the emergency protocol — a series of evasive maneuvers programmed into the pod before the first trip. Little Blue responded, but not with the usual precision. The Abyss Beast swam with something that looked like fear, and its song changed from a garbled broadcast to a raw, biological sound that Old Joe recognized immediately.

It was the same sound a creature made when it knew it was going to die.

The Natural Guardians' patrol boat appeared through the salt mist like a vision from a religious text: white, pristine, and utterly merciless. On its deck stood figures in white armor — not military armor, but the ceremonial armor of a faction that considered itself the guardian of natural purity. They believed that hybrid creatures like Little Blue were an abomination, a violation of the natural order, and that it was their duty to cleanse the world of such things.

Old Joe had never met a Natural Guardian in person. He didn't disagree with their ideology, necessarily — he just disagreed with their methods. Killing a creature for being different seemed like a waste to him. A terrible, pointless waste.

The patrol boat's EM cannon charged. Old Joe watched the blue light build in the cannon's barrel and felt something that might have been grief if grief could be felt by a mechanic who had spent his entire adult life fixing things that other people had broken.

The shot hit Little Blue at the exact moment the Abyss Beast reached for the surface, its mouth opening to swallow the pod and deliver it home.

The electromagnetic pulse was visible — a wave of distorted air that spread outward from the point of impact. Little Blue's body convulsed, its iridescent scales flashing through every color of the spectrum before going dull and gray. The neural chip sparked and died. The song stopped.

The pod sank. Old Joe fell with it, hitting the water hard, his prosthetic arm clicking frantically as he struggled to keep the pod from dragging him down.

Inside the sinking pod, pressed against the transparent wall by the force of descending water, Old Joe saw Little Blue's body drift past. The Abyss Beast's eyes were open, and they were looking at him. And in those dark, wide eyes, Old Joe saw something that he would carry for the rest of his life:

Not fear. Not pain.

Recognition.

Little Blue had known him. The creature had known him across the boundary between species, between biology and machinery, between the natural world and the abomination they had become together. And in its final moment, Little Blue had looked at him and RECOGNIZED him.

The pod hit the platform's deck with a bone-jarring thud. Old Joe tumbled out of it, coughing and gasping, his prosthetic arm clicking a rhythm that slowly synchronized with the faint, residual data signal still leaking from Little Blue's dead neural chip.

The signal was the song. A garbled, dying, half-digital half-biological song that contained fragments of old-world data, biological distress signals, and something that might have been gratitude. Old Joe couldn't tell the difference anymore. He sat on the platform deck, water pooling around him, and listened to the rust song of a creature that had been both natural and artificial, both beautiful and wrong, both alive and already gone.

Above him, the salt sea was quiet. The sky was quiet. The rusting platform creaked in the wind.

And Old Joe's prosthetic arm kept clicking.
