When I blew the last note, I was wrung out as a washcloth, but I summoned the energy to zip over to the hatch and block it. She calmly untied and floated over to me.

I looked in her eyes, silvered slanted cat-eyes, eyes that I'd been staring into all afternoon, and watched the smile that started at their corners and spread right down to her long, elegant toes. She looked back at me, then, at length, grabbed ahold of my joint again.

"You'll do," she said, and led me to her sleeping quarters, across the station.

We didn't sleep.

Zoya had been an early network engineer for the geosynch broadband constellations that went up at the cusp of the world's ascent into Bitchunry. She'd been exposed to a lot of hard rads and low gee and had generally become pretty transhuman as time went by, upgrading with a bewildering array of third-party enhancements: a vestigial tail, eyes that saw through most of the RF spectrum, her arms, her fur, dogleg reversible knee joints and a completely mechanical spine that wasn't prone to any of the absolutely inane bullshit that plagues the rest of us, like lower-back pain, intrascapular inflammation, sciatica and slipped discs.

I thought I lived for fun, but I didn't have anything on Zed. She only talked when honking and whistling and grabbing and kissing wouldn't do, and routinely slapped upgrades into herself on the basis of any whim that crossed her mind, like when she resolved to do a spacewalk bare-skinned and spent the afternoon getting tin-plated and iron-lunged.

I fell in love with her a hundred times a day, and wanted to strangle her twice as often. She stayed on her spacewalk for a couple of days, floating around the bubble, making crazy faces at its mirrored exterior. She had no way of knowing if I was inside, but she assumed that I was watching. Or maybe she didn't, and she was making faces for anyone's benefit.

But then she came back through the lock, strange and wordless and her eyes full of the stars she'd seen and her metallic skin cool with the breath of empty space, and she led me a merry game of tag through the station, the mess hall where we skidded sloppy through a wobbly ovoid of rice pudding, the greenhouses where she burrowed like a gopher and shinnied like a monkey, the living quarters and bubbles as we interrupted a thousand acts of coitus.

You'd have thought that we'd have followed it up with an act of our own, and truth be told, that was certainly my expectation when we started the game I came to think of as the steeplechase, but we never did. Halfway through, I'd lose track of carnal urges and return to a state of childlike innocence, living only for the thrill of the chase and the giggly feeling I got whenever she found some new, even-more-outrageous corner to turn. I think we became legendary on the station, that crazy pair that's always zipping in and zipping away, like having your party crashed by two naked, coed Marx Brothers.

When I asked her to marry me, to return to Earth with me, to live with me until the universe's mainspring unwound, she laughed, honked my nose and my willie and shouted, "YOU'LL DO !"

I took her home to Toronto and we took up residence ten stories underground in overflow residence for the University. Our Whuffie wasn't so hot earthside, and the endless institutional corridors made her feel at home while affording her opportunities for mischief.

But bit by bit, the mischief dwindled, and she started talking more. At first, I admit I was relieved, glad that my strange, silent wife was finally acting normal, making nice with the neighbors instead of pranking them with endless honks and fanny-kicks and squirt guns. We gave up the steeplechase and she had the doglegs taken out, her fur removed, her eyes unsilvered to a hazel that was pretty and as fathomable as the silver had been inscrutable.

We wore clothes. We entertained. I started to rehearse my symphony in low-Whuffie halls and parks with any musicians I could drum up, and she came out and didn't play, just sat to the side and smiled and smiled with a smile that never went beyond her lips.

She went nuts.

She shat herself. She pulled her hair. She cut herself with knives. She accused me of plotting to kill her. She set fire to the neighbors' apartments, wrapped herself in plastic sheeting, dry-humped the furniture.

She went nuts. She did it in broad strokes, painting the walls of our bedroom with her blood, jagging all night through rant after rant. I smiled and nodded and faced it for as long as I could, then I grabbed her and hauled her, kicking like a mule, to the doctor's office on the second floor. She'd been dirtside for a year and nuts for a month, but it took me that long to face up to it.

The doc diagnosed nonchemical dysfunction, which was by way of saying that it was her mind, not her brain, that was broken. In other words, I'd driven her nuts.

You can get counseling for nonchemical dysfunction, basically trying to talk it out, learn to feel better about yourself. She didn't want to.

She was miserable, suicidal, murderous. In the brief moments of lucidity that she had under sedation, she consented to being restored from a backup that was made before we came to Toronto.

I was at her side in the hospital when she woke up. I had prepared a written synopsis of the events since her last backup for her, and she read it over the next couple days.

"Julius," she said, while I was making breakfast in our subterranean apartment. She sounded so serious, so fun-free, that I knew immediately that the news wouldn't be good.

"Yes?" I said, setting out plates of bacon and eggs, steaming cups of coffee.

"I'm going to go back to space, and revert to an older version." She had a shoulderbag packed, and she had traveling clothes on.

Oh, shit. "Great," I said, with forced cheerfulness, making a mental inventory of my responsibilities dirtside. "Give me a minute or two, I'll pack up. I miss space, too."

She shook her head, and anger blazed in her utterly scrutable hazel eyes. "No. I'm going back to who I was, before I met you."

It hurt, bad. I had loved the old, steeplechase Zed, had loved her fun and mischief. The Zed she'd become after we wed was terrible and terrifying, but I'd stuck with her out of respect for the person she'd been.

Now she was off to restore herself from a backup made before she met me. She was going to lop 18 months out of her life, start over again, revert to a saved version.

Hurt? It ached like a motherfucker.

I went back to the station a month later, and saw her jamming in the sphere with a guy who had three extra sets of arms depending from his hips. He scuttled around the sphere while she played a jig on the piano, and when her silver eyes lit on me, there wasn't a shred of recognition in them. She'd never met me.

I died some, too, putting the incident out of my head and sojourning to Disney World, there to reinvent myself with a new group of friends, a new career, a new life. I never spoke of Zed again-especially not to Lil, who hardly needed me to pollute her with remembrances of my crazy exes.

***

If I was nuts, it wasn't the kind of spectacular nuts that Zed had gone. It was a slow, seething, ugly nuts that had me alienating my friends, sabotaging my enemies, driving my girlfriend into my best friend's arms.

I decided that I would see a doctor, just as soon as we'd run the rehab past the ad-hoc's general meeting. I had to get my priorities straight.

I pulled on last night's clothes and walked out to the Monorail station in the main lobby. The platform was jammed with happy guests, bright and cheerful and ready for a day of steady, hypermediated fun. I tried to make myself attend to them as individuals, but try as I might, they kept turning into a crowd, and I had to plant my feet firmly on the platform to keep from weaving among them to the edge, the better to snag a seat.

The meeting was being held over the Sunshine Tree Terrace in Adventureland, just steps from where I'd been turned into a road-pizza by the still-unidentified assassin. The Adventureland ad-hocs owed the Liberty Square crew a favor since my death had gone down on their turf, so they had given us use of their prize meeting room, where the Florida sun streamed through the slats of the shutters, casting a hash of dust-filled shafts of light across the room. The faint sounds of the tiki-drums and the spieling Jungle Cruise guides leaked through the room, a low-key ambient buzz from two of the Park's oldest rides.

There were almost a hundred ad-hocs in the Liberty Square crew, almost all second-gen castmembers with big, friendly smiles. They filled the room to capacity, and there was much hugging and handshaking before the meeting came to order. I was thankful that the room was too small for the de rigeur ad-hoc circle-of-chairs, so that Lil was able to stand at a podium and command a smidge of respect.

"Hi there!" she said, brightly. The weepy puffiness was still present around her eyes, if you knew how to look for it, but she was expert at putting on a brave face no matter what the ache.

The ad-hocs roared back a collective, "Hi, Lil!" and laughed at their own corny tradition. Oh, they sure were a barrel of laughs at the Magic Kingdom.

"Everybody knows why we're here, right?" Lil said, with a self-deprecating smile. She'd been lobbying hard for weeks, after all. "Does anyone have any questions about the plans? We'd like to start executing right away."

A guy with deliberately boyish, wholesome features put his arm in the air. Lil acknowledged him with a nod. "When you say 'right away,' do you mean-"

I cut in. "Tonight. After this meeting. We're on an eight-week production schedule, and the sooner we start, the sooner it'll be finished."

The crowd murmured, unsettled. Lil shot me a withering look. I shrugged. Politics was not my game.

Lil said, "Don, we're trying something new here, a really streamlined process. The good part is, the process is short . In a couple months, we'll know if it's working for us. If it's not, hey, we can turn it around in a couple months, too. That's why we're not spending as much time planning as we usually do. It won't take five years for the idea to prove out, so the risks are lower."

Another castmember, a woman, apparent 40 with a round, motherly demeanor said, "I'm all for moving fast-Lord knows, our pacing hasn't always been that hot. But I'm concerned about all these new people you propose to recruit-won't having more people slow us down when it comes to making new decisions?"

No , I thought sourly, because the people I'm bringing in aren't addicted to meetings .
