Grey throat bobbing, the chick walked toward the parent under the ice.
Split-Beak called from the open white behind it. A full living beat crossed the wind, carrying hunger, recognition, and the adult's long trip from the sea.
Halfway around, the chick stopped.
Its copied parent called beneath its feet.
Black-green frost opened a line in the snow, and the chick followed the nearer answer.
Aylin moved first. Black-Crown struck her boot again and spread both flippers across the chick line.
"I see the crack," she said.
Black-Crown lowered its beak. Alarm drove the birds behind it closer around their young.
Jiang understood the refusal. A human stranger and a wounded stranger had brought the wrong rhythm. Letting either rush among chicks would turn protection into faith.
Under the grey throat, ice clicked.
Split-Beak broke into a heavy run. Its feet landed wide, body rolling from side to side while the adult saved its breath for another identity call.
From below came the copied call first.
It used both of Split-Beak's acoustic sources now. The fragment had heard enough living songs to place the beat correctly, yet it entered while two other adults were still calling.
Real birds left each other room.
Gredudande wanted every voice at once.
Jiang listened for the theft rather than the parent. Between Split-Beak's long notes came a short gap where the chick should have heard only wind.
From below, the fragment filled that gap.
Jiang opened his beak.
Black-Crown hit him in the breast.
Across the sling, the impact rolled Jiang onto his injured side. Cloth caught under his shoulder, and blood warmed the wrap before he could right himself.
Aylin dropped beside him. "It thinks you are helping the thing."
Jiang shoved his working foot under his belly while the bad one dragged flat. From Black-Crown's place, the danger was simple: a call gave the fragment more of Jiang; silence left the chick following a parent without a body.
Jiang struck the sling once.
"Your choice," Aylin said. "I will show the ice."
She pulled the silver sheet from her shoulders and cast it flat between the chick group and the growing frost. The wind tried to fold it. Aylin planted both knees on one edge and pressed her palms into the other.
Cool essence ran across the silver.
Black-green frost stained the silver cleanly, exposing three roots beneath the chick: one toward Split-Beak, one toward Jiang, and one descending through the ice toward dark water.
Aylin looked at him. "It wants whichever identity answers."
Jiang already knew which identity to risk: his own.
Through the next adult song, he waited while wind shook snow from his back and the chick stepped onto the first dark line. Split-Beak fought through closing birds from the far side.
When the living call ended, Jiang sang into the empty space after it.
Pain roughened one acoustic source. The other held steady long enough to make his own beat. He gave the colony an unfamiliar adult, wounded and close, with no claim of parenthood in the rhythm.
Heads turned toward him.
So did the fragment.
Split-Beak's copied answer broke off under the chick. Jiang's lower note came back from beneath his own belly, cleaner than the sound he had produced.
Black-green frost abandoned the parent root and raced along the silver sheet toward him.
Black-Crown tracked the moving stain. It pivoted from Jiang toward the sheet while keeping one flipper between the newcomers and the chicks. Its suspicion had found a second target, not disappeared.
Jiang wanted that caution kept between the fragment and every chick.
"Now I understand," Aylin said.
She drove both palms down.
Cool essence pinned the visible stain to the sheet for one breath. The descending root kept moving under the ice, but the stolen identity remained close enough for Jiang to pull.
Now the grey-throated chick heard only one Split-Beak.
Its head snapped toward the living adult.
Split-Beak called again, shorter and lower. The chick answered with its own high signature and ran across the frost line.
Ice broke beneath one foot.
Black water showed through a hole smaller than the chick's body. Its leg plunged to the belly, wetting down that could hold no warmth after the wind reached it.
Penguin Instincts changed the alarm inside Jiang. Water in adult feathers was trouble; water in that loose down could kill the chick before hunger had another chance.
Split-Beak was still several bodies away.
Black-Crown moved to block Jiang again.
Jiang dropped his breast to the ice and pushed.
His working foot drove once. The sling slid over packed snow, low enough to pass beneath Black-Crown's spread flipper. His bad foot trailed behind him, and the shoulder wrap pulled tight with every belly length.
From the hole came Jiang's stolen voice.
Jiang kept his beak shut. He reached the chick while it beat both flippers against the edge and widened the break.
Down filled his mouth when he caught the loose feathers behind its neck.
Screaming, the chick pecked his face. Jiang turned his head with the blow, keeping his grip gentle enough to hold feathers rather than skin.
He pulled the chick sideways.
With his left foot flat beneath him, Jiang scraped his right claws through snow until they caught hard ice. One shove rolled the chick's wet leg out of the hole.
Aylin's essence cracked behind him.
Freed from Aylin's silver, the stain dove through open water. Black-green light spread below the ice in the direction the returning adults had come from.
Its root had entered the sea route.
Jiang released the chick.
It ran toward Split-Beak, one wet leg kicking snow. The adult dropped low, answered the chick's call at beak range, and folded its body around the soaked side.
At Split-Beak's beak, the chick demanded food.
Food passed between them while wind caught the wet down. The feeding was small, but it belonged to the living pair and no copied rhythm entered it.
Jiang watched from his belly.
Hunger cramped under his breast. The last fish on Earth felt like a story someone else had eaten.
Split-Beak finished feeding and faced him.
Split-Beak walked close enough for Jiang to see old pale tissue inside the split tip. It touched its beak to the chick's wet leg, then looked at the open blood on Jiang's shoulder.
Jiang expected a warning strike.
Split-Beak pecked him between the eyes.
Controlled and deeply insulting, the blow drove Jiang's beak into the snow.
Split-Beak stepped back between Jiang and the chick. The adult's choice held both facts at once: Jiang had pulled its young from the water, and danger still moved with him.
Aylin made a ruined sound that might have become a laugh before her throat stopped it.
Split-Beak called over him. Penguin Instincts gave Jiang a tight knot of recognition, anger, chick, danger, and leave.
Saving one life had changed the bird's judgment by exactly one life.
Nothing more came with it.
Black-Crown reached the hole and lowered its breast against the ice. Adults behind it copied the spread posture, sharing their weight while others pushed the chicks away from the weak patch.
Aylin rolled the stained sheet toward herself. The green-black line had burned through the silver, leaving a long opening that pointed toward the sea.
"It left the chick," she said. "It took their food road."
Jiang tried to stand on the right, but his left foot stayed flat and the shoulder failed halfway up, dropping him onto the sling.
Aylin moved beside him, keeping her hands clear until his beak tapped once. Then she lifted only the rear cloth and turned his chest away from the wind.
Split-Beak led the grey-throated chick back toward the moving group. Black-Crown stayed between the newcomers and every young bird that passed.
Behind Split-Beak, the rookery closed.
Adults shifted into the wind. Chicks disappeared among dark legs and warm brood folds. The huddle tightened around its own, leaving Jiang and Aylin with the torn silver sheet and a low ridge of snow.
The System remained silent. Blood soaked Jiang's wrap, his left foot lay flat, and the stolen voice moved through the route feeding the colony.
Outside the huddle, the first hard gust struck them.
Under the ice, his stolen voice traveled toward the sea.
