Vin gritted her teeth, burning iron as she fell. She Pulled on a pouch on her desk, whipping the coins into her hand. She hit the ground on her side, other hand down, and threw herself back to her feet. She dumped a shower of coins from the pouch into her hand, then raised them at Zane.

Blood dripped from her chin. She threw the coins out. Zane moved to Push them away.

Vin smiled, then burned duralumin as she Pushed. The coins snapped forward, and the wind of their sudden passing parted the mist on the ground, revealing the floor beneath.

The room shook.

And in an eyeblink, Vin found herself slammed back against the wall. She gasped in surprise, breath knocked from her lungs, her vision swimming. She looked up, disoriented, surprised to find herself on the ground again.

"Duralumin," Zane said, still standing with a hand up before him. "TenSoon told me about it. We deduced you must have a new metal from the way you can sense me when my copper is on. After that, a little searching, and he found that note from your metallurgist, which handily had the instructions for making duralumin."

Her addled mind struggled to connect ideas. Zane had duralumin. He'd used the metal, and had Pushed against one of the coins she'd shot at him. He must have Pushed behind himself as well, to keep from being forced backward as his weight met hers.

And her own duralumin-enhanced Push had slammed her against the wall. She had trouble thinking. Zane walked forward. She looked up, dazed, then scrambled away on hands and knees, crawling in the mists. It was at face level, and her nostrils tickled as she inhaled the cool, quiet chaos.

Atium. She needed atium. But, the bead was in TenSoon's shoulder, she couldn't Pull it to herself. The reason he carried it there was that the flesh protected it from being affected by Allomancers. Just like the spikes piercing an Inquisitor's body, just like her own earring. Metal inside—or even piercing—a person's body could not be Pulled or Pushed except with the most extreme of Allomantic forces.

But she'd done it once. When fighting the Lord Ruler. It hadn't been her own power, or even duralumin, that had let her accomplish it. It had been something else. The mists.

She'd drawn upon them.

Something hit her on her back, pushing her down. She rolled over, kicking upward, but her foot missed Zane's face by a few atium-aided inches. Zane slapped her foot aside, then reached down, slamming her against the floor by her shoulders.

Mists churned around him as he looked down at her. Through her terror, she reached out for the mists, as she had over a year before when fighting the Lord Ruler. That day, they had fueled her Allomancy, giving her a strength that she shouldn't have had. She reached out for them, begging for their help.

And nothing happened.

Please. . ..

Zane slammed her down again. The mists continued to ignore her pleas.

She twisted, Pulling against the window frame to get leverage, and pushed Zane to the side. They rolled, Vin coming around on top.

Suddenly, both of them lurched off the floor, bursting out of the mists and flying toward the ceiling, thrown upward as Zane Pushed against coins on the floor. They slammed against the ceiling, Zane's body pushing against hers, pinning her to the wooden planks. He was on top again—or, rather, he was on the bottom, but that was now the point of leverage.

Vin gasped. He was so strong. Stronger than she. His fingers bit into the flesh of her arms despite her pewter, and her side ached from her earlier wounds. She was in no condition to fight—not against another Mistborn.

Especially not one with atium.

Zane continued to Push them against the ceiling. Vin's hair fell toward him, and mists churned the floor below, like a whirlpool vortex that was slowly rising.

Zane released his Push, and they fell. Yet, he was still in control. He spun her, throwing her down below him as they entered the mists again. They hit the ground, the blow knocking the wind from Vin's lungs yet again. Zane loomed above her, speaking through gritted teeth.

"All that effort, wasted," he hissed. "Hiding an Allomancer in Cett's hirelings so that you would suspect him of attacking you at the Assembly. Forcing you to fight in front of Elend so that he'd be intimidated by you. Pushing you to explore your powers and kill so that you'd realize just how powerful you truly are. All wasted!"

He leaned down. "You. Were. Supposed. To. Save me!" he said, his face just inches from hers, breathing heavily. He pinned one of her struggling arms to the floor with his knee, and then, in a strangely surreal moment, he kissed her.

And at the same time, he rammed his dagger into the side of one of her breasts. Vin tried to cry out, but his mouth held hers as the dagger cut her flesh.

"Be careful, Master!" OreSeur—TenSoon—suddenly yelled. "She knows much about kandra!"

Zane looked up, his hand stilled. The voice, the pain, brought lucidity to Vin. She flared tin, using the pain to shock herself awake, clearing her mind.

"What?" Zane asked, looking down toward the kandra.

"She knows, Master," TenSoon said. "She knows our secret. The reason why we served the Lord Ruler. The reason why we serve the Contract. She knows why we fear Allomancers so much."

"Be silent," Zane commanded. "And speak no more."

TenSoon fell silent.

Our secret. . .Vin thought, glancing over at the wolfhound, sensing the anxiety in his canine expression. He's trying to tell me something. Trying to help me.

Secret. The secret of the kandra. The last time she'd tried Soothing him, he'd howled with pain. Yet, she saw permission in his expression. It was enough.

She slammed TenSoon with a Soothing. He cried out, howling, but she Pushed harder. Nothing happened. Gritting her teeth, she burned duralumin.

Something broke. She was in two places at once. She could feel TenSoon standing by the wall, and she could feel her own body in Zane's grip. TenSoon was hers, totally and completely. Somehow, not quite knowing how, she ordered him forward, controlling his body.

The massive wolfhound's body slammed into Zane, throwing him off Vin. The dagger flipped to the ground, and Vin stumbled to her knees, grabbing her chest, feeling warm blood there. Zane rolled, obviously shocked, but he came to his feet and kicked TenSoon.

Bones broke. The wolfhound tumbled across the floor—right toward Vin. She snatched the dagger off the ground as he rolled to her feet, then plunged it into his shoulder, cutting the shoulder, her fingers feeling in the muscle and sinew. She came up with bloodied hands and a single bead of atium. She swallowed it with a gulp, spinning toward Zane.

"Now let's see how you fare," she hissed, burning atium. Dozens of atium shadows burst from Zane, showing her possible actions he could take—all of them ambiguous. She would be giving off the same confusing mess to his eyes. They were even.

Zane turned, looking into her eyes, and his atium shadows disappeared.

Impossible! she thought. TenSoon groaned at her feet as she realized that her atium reserve was gone. Burned away. But the bead had been so large. . ..

"Did you think I'd give you the very weapon you needed to fight me?" Zane asked quietly. "Did you think I'd really give up atium?"

"But—"

"A lump of lead," Zane said, walking forward. "Plated with a thin layer of atium around it. Oh, Vin. You really need to be more careful whom you trust."

Vin stumbled backward, feeling her confidence wilt. Make him talk! she thought. Try to get his atium to run out.

"My brother said that I shouldn't trust anyone. . ." she mumbled. "He said. . .anyone would betray me."

"He was a wise man," Zane said quietly, standing chest-deep in mists.

"He was a paranoid fool," Vin said. "He kept me alive, but he left me broken."

"Then he did you a favor."

Vin glanced toward TenSoon's mangled, bleeding form. He was in pain; she could see it in his eyes. In the distance she could hear. . .thumping. She'd turned her bronze back on. She looked up slowly. Zane was walking toward her. Confident.

"You've been playing with me," she said. "You drove a wedge between me and Elend. You made me think he feared me, made me think he was using me."

"He was," Zane said.

"Yes," Vin said. "But it doesn't matter—not the way you made it seem. Elend uses me. Kelsier used me. We use each other, for love, for support, for trust."

"Trust will kill you," he said.

"Then it is better to die."

"I trusted you," he said, stopping before her. "And you betrayed me."

"No," Vin said, raising her dagger. "I'm going to save you. Just like you want." She snapped forward and struck, but her hope—that he'd run out of atium—was in vain. He sidestepped indifferently; he let her dagger come within an inch of striking, but he was never really in danger.

Vin spun to attack, but her blade cut only air, skimming along the top of the rising mists.

Zane moved before her next attack came, dodging even before she knew what she was going to do. Her dagger stabbed the place where he had been standing.

He's too fast, she thought, side burning, mind thumping. Or was that the Well of Ascension thumping. . ..

Zane stopped just in front of her.

I can't hit him, she thought with frustration. Not when he knows where I'll strike before I do!

Vin paused.

Before I do. . ..

Zane stepped away to a place near the center of the room, then kicked her fallen dagger into the air and caught it. He turned back toward her, mist trailing from the weapon in his hand, jaw set and eyes dark.

He knows where I'll strike before I do.

Vin raised her dagger, blood trickling down face and side, thunderous drumbeats booming in her mind. The mist was nearly up to her chin.

She cleared her mind. She didn't plan an attack. She didn't react to Zane as he ran toward her, dagger raised. She loosened her muscles and closed her eyes, listening to his footsteps. She felt the mist rise around her, churned by Zane's advent.

She snapped her eyes open. He had the dagger raised; it glittered as it swung. Vin prepared to attack, but didn't think about the strike; she simply let her body react.

And she watched Zane very, very carefully.

He flinched just slightly to the left, open hand moving upward, as if to grab something.

There! Vin thought, immediately wrenching herself to the side, forcing her instinctive attack out of its natural trajectory. She twisted her arm—and dagger—midswing. She had been about to attack left, as Zane's atium had anticipated.

But, by reacting, Zane had shown her what she was going to do. Let her see the future. And if she could see it, she could change it.

They met. Zane's weapon took her in the shoulder. But Vin's knife took him in the neck. His left hand closed on empty air, snatching at a shadow that should have told him where her arm would be.

Zane tried to gasp, but her knife had pierced his windpipe. Air sucked through blood around the blade, and Zane stumbled back, eyes wide with shock. He met her eyes, then collapsed into the mists, his body thumping against the wooden floor.

Zane looked up through the mists, looked up at her. I'm dying, he thought.

Her atium shadow had split at the last moment. Two shadows, two possibilities. He'd counteracted the wrong one. She'd tricked him, defeated him somehow. And now he was dying.
