It was the second time that Mattie found herself naked in Sebastian’s presence, and from his pretend lightheadedness and joking manner she surmised that he was thinking about it too. She wanted to ask him now, why did he go along with it? Why did he make love to her—was it a fetish of a mechanic enamored with intricate devices and easily prompted to express his affection the moment a device resembled a girl, or was it something else? She did not know how to ask, and her sluggish mind refused to do any more work than was strictly necessary—another self-preservation mode Loharri built into her, undoubtedly passing along the ridiculous desire to live despite one’s inevitable mortality.
Sebastian checked her joints, oiling and adjusting fiddly little parts in her knees. It hurt only a little.
“Pity,” Sebastian said. “I wish you didn’t feel it, like other automatons.” He still regretted their encounter, he still wished she hadn’t shown up to remind him.
“There’s a module in my head that disconnects the sensation,” Mattie said. “Only I don’t really know where it is exactly. And I didn’t like the last time it was used—I think this is why I’m so poorly now.”
“I won’t touch it,” Sebastian promised. “But I’ll have to check inside your head, to make sure there’s nothing broken there.”
“Last time you said you didn’t know how I worked,” Mattie said.
“I don’t. But I can still see if the gears are misaligned or if the connectors are missing or detached. Now that I’ve seen how it’s supposed to look.”
“I think I will need winding soon,” Mattie whispered, her voice giving out and then coming back again. “I need my key—make sure Iolanda gets it for me.”
“I will,” Sebastian said. His voice sounded so earnest that Mattie believed him. “I promise you I will.” He thought a bit, his hand clasping his chin absentmindedly. “Maybe I could take a cast of the keyhole and machine you a new one. I have the equipment here.”
Of course, Mattie thought. They machined keys—Iolanda and the rest had access to every important keyhole in the city. That was why they could place the explosives wherever they wanted. In her muddled state, the walls of the cave—dimly lit, just bare hints of solid matter under the gauze of shadows-reminded her of the dark paneling of Loharri’s workshop. It smelled the same, and was just as cluttered, and Sebastian became Loharri in her mind and then himself again. Perhaps that was why the thought of a second key in another mechanic’s hands scared her.
“No,” she whispered. “Just let Iolanda or Niobe get my only key—I do not want more than one, I do not want anyone but me to have it. And I don’t want anyone but them touching it.”
Sebastian smiled. “Not even me?”
“Especially not you,” Mattie said. “No offense meant.”
“None taken,” he replied. “Maybe just a temporary one? I’ll give it to you right away.”
The vexing survival module let itself be known again. “Yes,” Mattie whispered, and the shadows grew darker around her. “Just a temporary one then.”
“I will need to take a print,” Sebastian said.
Mattie nodded her consent and watched him take the glass bubble off the lamp, and heat a metal tin over the flames. When it started crackling and smelling of hot metal, he dropped a lump of wax into the tin, letting it soften but not melt. He tossed the tin down and blew on his fingers. The lump of wax had grown transparent around the edges, and Sebastian rolled in his hands, letting it cool a bit, stretching it between his fingers.
When the warm, fragrant wax touched her skin, Mattie gasped. This touch felt so alive, so gentle. The pliable wax pushed into the opening of the keyhole, and Mattie tensed, waiting for the turn of a key. None came, of course—it was silly to expect one, and yet she was so attuned to being wound that she could not completely extinguish her anticipation and excitement.
“Stay still,” Sebastian whispered. He pressed on the wax lump with his hand, and Mattie looked away. Not because she felt awkward (although she did), but because he was so mechanic-like now—his lips pursed in concentration, his eyes narrowed, he thought only about the task at hand, forgetting everything about Mattie. It struck her, in the slow, grating way her thoughts had acquired, how much like Loharri he was. She found it neither comforting nor disturbing, just odd.
Sebastian extracted the wax and squinted at it. “Son of a bitch,” he muttered.
“What?”
Sebastian shook his head. “Look.”
The wax looked like a simple narrow cylinder, devoid of any marks. “It doesn’t look like my key,” Mattie said.
“Of course it doesn’t. It’s protected, see—the outer opening is more narrow than the internal mechanism.”
“I think he told me once that it’s a complex key.”
“That’s an understatement,” Sebastian agreed. “It opens up once it’s inside and fits into the grooves. But I can’t make a print of it.”
Mattie lowered her eyes. “He didn’t want me to be able to get a copy. Even if I had thought of it earlier, I couldn’t have done it.”
