Duun held out his arms to Thorn and Thorn laughed as he plunged into Duun's arms, all dusty-smelling.

"Again," Duun said, and set him upright, crouching again a little distance off to make Thorn run. Infant legs tried and failed, exhausted. Duun caught him, hugged him, licked his mouth and eyes, which Thorn did to him when Thorn had stopped laughing and gasping, clenching small five-fingered fists into Duun's trailing crest and the shorter hair of his forelock, and digging his face for a sly nip into the hollow of Duun's neck when he got the chance, but Duun ducked his head aside and got in a nip first.

Small unclawed feet drove at his lap, the small body strained and Thorn ducked down to bite him ungently in the chest.

"Ah!" Duun cried, seizing him in both hands, kneeling, lifting him kicking and squealing aloft at arm's length. "Ah! Devious!"

He hugged him again and Thorn bit again. He had gained teeth, and strength, but they were not teeth like Duun's. Duun bit at fingers and Thorn caught Duun's mouth and pushed back his lip to try his fingers on Duun's larger, sharper teeth. Duun nipped and Thorn rescued his hand and squealed.

There were more visits. "Bye, bye, bye," Thorn bade the meds sullenly from the porch. He squatted down naked as he was and grimaced then. He had bit the chief med, and the med had come within a little of flicking an impudent youngster hard on the nose.

Cuckoo's Egg

But the med had stopped himself. Duun was standing there, hatani-cloaked in gray, arms folded.

The meds went away. Thorn made a rude sound and urinated on the step.

Duun went and snapped him soundly on the ear with thumb and forefinger. Thorn wailed.

"Bad," said Duun. The wail went on. Duun went into the house, into the kitchen and got his hand wet in the sink. Thorn followed, naked, holding hands out, wailing all the way and dancing in his distress.

"Shut up," Duun said. And flicked cold water in Thorn's face. Thorn blinked and howled and clawed frantically at Duun's legs, not in rage. Pick me up, that meant.

Duun picked him up, armful that he had become, rocked him with a swinging of his body in that way he had learned the infant liked. A small face nuzzled its way to his neck; this did not always mean biting. This time it did not. Thorn clung to him and snuffled, soiling his cloak with running eyes and nose.

"You were bad," Duun said. To such simplicities the philosophy of hatani bent nowadays. He swung from side to side and the sobs stopped. The thumb went in Thorn's mouth, irrepressible, though Thorn ate meat now, which Duun chewed for him and spat into his mouth. ("Not advisable," the meds said, obsessed with disease. But he did it, which was an old way, a hill way, and easier than urging a spoon past Thorn's dodging mouth, or cleaning up when Thorn fed himself and smeared it everywhere. Duun's mother and father had done this for him. He took perverse pleasure in performing this dutiful service. It shocked the meds. That gave him perverse pleasure too. He smiled at the meds. It was strange. They had become familiar with him. They looked him in the eyes, at least more than once in the visit. "Elludmingi sends regards," they said. "I sent mine," he said in return. And perversely added: "So does my son." Thatsent them on their way in haste. Doubtless to take notes.)

He rocked Thorn and sang to him, absently: "Wei-na-mei, wei-na-mei."

And Thorn grew quiet in his arms. "You're getting too big to hold," Duun said. "Too big to make puddles on the step."

That night, when they sat before the fire (the spring nights were cold) Thorn crawled into his lap and sat there a while; and got up on his feet in the triangle between Duun's crossed legs and touched Duun's face, the scarred side. Duun caught the hand with his maimed one. And let it go.

"It's a scar," Duun said.

He did not prevent the exploration. He made himself patient. He shut his eyes and let Thorn do what he liked, until Thorn pulled savagely on both his ears, which was challenge. Duun's eyes flashed open.

"Ah!"Duun cried, drawing back his lips in a grimace. Thorn recoiled and stumbled on Duun's legs; Duun caught him in mid-fall and rolled with him, rolled holding him in his arms, never coming on him with his weight.

Thorn screamed, and gasped, and when Duun bit, bit back, and screamed and squealed till Duun clamped a hand over his mouth and held it there.

Thorn grew still. The eyes stayed wide with shock. So. So. Fright, not fight.

Duun gathered him to his breast and licked his eyes till Thorn had begun to pant, recovering his lost breath. For a moment Duun was worried. Small hands clutched at him.

He gripped Thorn by both arms and held him up. Grinned. Thorn refused to be appeased.

That night Thorn waked howling at Duun's side, short sharp yelps, gasps for breath. "Thorn!" Duun cried, and turned on lights and snatched him up, thinking he had rolled on the infant and hurt him in some way; but it was nightmare.

Thorn held to him. It was Duun Thorn feared. That was the nightmare.

"Ah," Duun cried, falling back, dragging Thorn atop him. "Ah! you hurt me! You hurt me—" To give him the upper hand. He had no pride in this.

"Duun," Thorn cried and snuggled close.

Sometimes genes were truer than teaching. Alien. Thorn clung to what had frightened him.

"Duun, Duun, Duun—"

Duun held him. It was all Thorn understood.

There was a day, in the morning bath, that Thorn noticed his own naked skin. Thorn scrubbed at Duun's belly and at his own with a rough-textured sponge. Dropped the sponge and put both hands on his own belly, rubbed it thoughtfully. When he looked up thoughts passed in his milk-and-storm eyes, with a little knitting of his brow. "Slick," he said of himself. His speech did not go as fast as a shonun child. But there was a difference of mouths and tongues. "Slick."

Perhaps Thorn wanted to ask, if his young mind had thought of it, when his own pelt would begin to grow. The hair on his head was abundant, tousled curls, which had finally settled on a faded, earthy brown. The eyes had never changed. It was a dangerous time.

Duun took Thorn from the bath and held him in his left arm, hugged him close in front of the mirror. Thorn had seen mirrors. He had one for a toy.

He had seen this one many times.

Today there was distress in young Thorn's eyes, and thoughts were going on. Thorn had never seen a shonun child. He had never seen other shonunin, except the meds. Perhaps some terrible thing was dawning on his mind, put together of little wordless pieces, images in mirrors, smooth bellies, a facility for making water in a long, long arc, which was for a time his nuisancefully chiefest talent. He spread his five-fingered hand at Thorn-in-the-mirror, in a way that should bring claws and did not; he grimaced at this Thorn as if to frighten him to flight. (Go away, ugly Thorn.) He flexed the fingers yet again. Made faces.

Cuckoo's Egg

Duun turned them both away. Bounced him to distract him.

After that Thorn did not mention the difference of their skins. Only from time to time there were small moments which Duun caught: a moment of rest when Thorn, lying beside Duun, reached and stroked his arm, turning the fur this way and that. Another when Thorn, finding Duun's hand conveniently palm up, dragged it closer to him across Duun's lap and played with it, fingering the dissimilar geometries of the palm, working doggedly at the fingers to make the claws come out. Duun cooperated. It was his right hand. It was not the deformity Thorn explored, but an ability which surely Thorn envied; and Duun was suddenly aware of a silence within the child, a secrecy which had grown all unawares, that small walled-off place which was an independent mind. Thorn had arrived at selfhood, a self which came out to explore the world and retreated with scraps of things which had to be examined with care, compared (sign of a complex mind) against other truths: Thorn had arrived at self-defense, disappointed in his body, it seemed. Aware of his own deformity. And not, truly, aware of Duun's. Duun was Duun. Duun had always had scars; they were part of Duun as the sun was part of the world. There was no past.
