Shepherd no longer leaned with the top of his skull jammed into the juncture of walls. He had taken a step backward. He stood erect, head up, eyes focused intently on something that appeared to be a lot more interesting than anything Jilly could see.

He had raised his right hand again, as if taking an oath, but he hadn't started to wave. As Jilly arrived at his side, Shep reached in front of his face, to the point in midair at which he'd been staring, and between his thumb and forefinger, he took a pinch of… a pinch of nothing, as far as she could tell. When he tweaked that pinch of air, however, the corner of the room began to fold in upon itself.

'No,' Jilly said breathlessly, and though she knew that Shepherd often recoiled from contact, she reached in front of him and put her hand atop his. 'Don't do this, sweetie.'

Multiple segments of the tricolored stripes on the wallpaper, previously mismatched only at the corner, now bent every which way at radical angles to one another, and the corner became so distorted that Jilly could not follow the floor-to-ceiling line of it.

At Shep's other side, Dylan placed one hand on his brother's shoulder. 'Stay here, buddy. Right here with us, safe with us.'

The folding motion halted, but the corner remained tweaked into a surreal geometry.

Jilly seemed to be looking at this small portion of the world through an octagonal prism. Her mind rebelled at the spectacle, which defied reason to an extent that even the radiant tunnel in the wall had not done.

With the palm of her right hand still against the back of Shep's right hand, Jilly was afraid to struggle with him, for fear that any movement she made would further fold here to there, wherever there might be this time. 'Smooth it out, honey,' she urged, tremors creasing her voice as strangely as the walls were folded before her. 'Let it go, sweetie. Smooth it out like it ought to be.'

Between thumb and forefinger, Shepherd still pinched the fabric of reality.

Slowly he turned his head to look at Jilly. He met her eyes as directly as he had met them only once before: when he'd been in the backseat of the Expedition outside the house on Eucalyptus Avenue, just after Dylan had rushed away without explanation. Then, Shep had flinched from eye contact, had looked at once away.

This time he held her gaze. His green eyes appeared as deep as oceans and seemed to be lit from within.

'Do you feel it?' he asked.

'Feel what?'

'Feel how it works, the round and round of all that is.'

She supposed that by transmission through his hand, he expected her to feel what he felt between his thumb and forefinger, but she was aware only of his warm skin, of the sharpness of his metacarpals and his knuckles. She expected to detect tremendous tension, as well, to have an awareness of how hard Shep must be straining to achieve this incredible feat, but he seemed to be relaxed, as though folding this place to another required no more effort than folding a towel.

'Do you feel the beautiful of all that is?' he asked, addressing her with a directness that had no element of autistic detachment.

As beautiful as the secret structure of reality might be, this close an encounter with the mystery of it did not delight her as it seemed to enchant Shepherd, but instead crystallized an ice of terror in her bones. She wanted not to understand, but only to persuade him to close this gateway before he fully opened it.

'Please smooth it out, sweetie. Smooth it out again so I can feel how it unfolds.'

Although her father had been shot to death a year ago in a drug deal gone bad, Jilly had the fearful notion that if Shepherd didn't unfold this, if instead he folded it all the way and took them from here to there, she would abruptly come face to face with her hateful old man, as she had often opened the apartment door to the sight of his dangerous smile. She expected Shep to swing wide the gate to Hell as easily as he opened a gate to California, facilitating a father-and-daughter reunion. Come to collect the eye insurance, baby girl. You got the eye-insurance premium? As though Shep might unwittingly give her father a chance to reach out from Beyond to make good on his unfulfilled threat, blinding her in not one eye, but in both.

Shep's gaze drifted away from her. He refocused on his thumb and forefinger.

He had tweaked the pinch of nothing from left to right. Now he tweaked it right to left.

The wildly angled stripes in the wallpaper realigned themselves. The unbroken line of the corner, floor to ceiling, became clearly visible again, without a single zig or zag. What she had seemed to see through an octagonal prism, she here saw undistorted.

Squinting at the pinch point where Shep still squeezed something between thumb and forefinger, Jilly thought she saw the air dimple like a puckered film of thin plastic wrap.

Then his pale fingers parted, releasing whatever extraordinary fabric he had held.

Even viewed from the side, his green eyes appeared to cloud, and in place of the ocean's depth that had been revealed, there came now a shallowness, and in place of enchantment… a melancholy.

'Good,' Dylan said with relief. 'Thank you, Shep. That was just fine. That was good.'

Jilly let go of Shep's hand, and he lowered it to his side. He lowered his head, too, staring at the floor, slumping his shoulders, as though, for an instant liberated, he had once more accepted the weight of his autism.

Dylan moved the second chair from the table near the window, and the three of them sat in a semicircle at the desk, in front of the laptop, with Shepherd safely in the middle, where he could be more closely watched.

The kid sat with his chin against his chest. His hands lay in his lap, turned up. He appeared to be reading his palms: the heart line, head line, lifeline – and the many meaningful lines radiating out of the web between thumb and forefinger, that area known as the anatomical snuffbox.

Jilly's mother read palms – not for money, but for hope. Mom was never interested solely in the heart line, head line, and lifelines, but equally in the anatomical snuffbox, the interdigital pads, the heel of the hand, the thenar eminence, and the hypothenar.

Arms crossed on her chest, Jilly sat with her hands fisted in her armpits. She didn't like having her palms read.

Reading palms, reading tea leaves, interpreting Tarot cards, casting horoscopes – Jilly wanted nothing to do with any of that. She would never concede control of her future to fate, not for a minute. If fate wanted control of her, fate would have to club her senseless and take control.

'Nanomachine,' Jilly said, reminding Dylan where they had been interrupted. 'Scouring plaque off artery walls, searching out tiny groups of cancer cells.'

He stared worriedly at Shepherd, then nodded and finally met Jilly's eyes. 'You get the idea. In the interview there on the laptop, Proctor talks a lot about nanomachines that'll also be nanocomputers with enough memory to be programmed for some pretty sophisticated tasks.'

In spite of the fact that all three of them appeared to be living proof that Lincoln Proctor wasn't a fool, Jilly found this chatter of technological marvels almost as difficult to believe as Shepherd's power to fold. Or maybe she simply didn't want to believe it because the implications were so nightmarish.

She said, 'Isn't this ridiculous? I mean, how much memory can you squeeze into a computer smaller than a grain of sand?'

'In fact, smaller than a mote of dust. The way Proctor tells it, with a little background: The first silicon microchips were the size of a fingernail and had a million circuits. The smallest circuit on the chip was one hundredth as wide as a human hair.'
