Zane finally turned away from Vin. "His Majesty was hoping for us to set a date and time, Your Majesty."

"I will send another message when I have made my decision," Elend said.

"Very well," Zane said, bowing slightly, though he used the move to catch Vin's eyes once again. Then he nodded once to Elend, and let the guards escort him away.

In the cold mist of early evening, Vin waited on the short wall of Keep Venture, OreSeur sitting at her side.

The mists were quiet. Her thoughts were far less serene.

Who else would he work for? she thought. Of course he's one of Straff's men.

That explained many things. It had been quite a while since their last encounter; Vin had begun to think that she wouldn't see the Watcher again.

Would they spar again, then? Vin tried to suppress her eagerness, tried to tell herself that she simply wanted to find this Watcher because of the threat he posed. But, the thrill of another fight in the mists—another chance to test her abilities against a Mistborn—made her tense with anticipation.

She didn't know him, and she certainly didn't trust him. That only made the prospect of a fight all the more exciting.

"Why are we waiting here, Mistress?" OreSeur asked.

"We're just on patrol," Vin said. "Watching for assassins or spies. Just like every night."

"Do you command me to believe you, Mistress?"

Vin shot him a flat stare. "Believe as you wish, kandra."

"Very well," OreSeur said. "Why did you not tell the king that you've been sparring with this Zane?"

Vin turned back toward the dark mists. "Assassins and Allomancers are my concern, not Elend's. No need to worry him yet—he has enough troubles at the moment."

OreSeur sat back on his haunches. "I see."

"You don't believe I'm right?"

"I believe as I wish," OreSeur said. "Isn't that what you just commanded me, Mistress?"

"Whatever," Vin said. Her bronze was on, and she had to try very hard not to think about the mist spirit. She could feel it waiting in the darkness to her right. She didn't look toward it.

The logbook never did mention what became of that spirit. It nearly killed one of the Hero's companions. After that, there was barely a mention of it.

Problems for another night, she thought as another source of Allomancy appeared to her bronze senses. A stronger, more familiar source.

Zane.

Vin hopped up onto the battlements, nodded farewell to OreSeur, then jumped out into the night.

Mist twisted in the sky, different breezes forming silent streams of white, like rivers in the air. Vin skimmed them, burst through them, and rode them like a bouncing stone cast upon the waters. She quickly reached the place where she and Zane had last parted, the lonely abandoned street.

He waited in the center, still wearing black. Vin dropped to the cobbles before him in a flurry of mistcloak tassels. She stood up straight.

He never wears a cloak. Why is that?

The two stood opposite one another for a few silent moments. Zane had to know of her questions, but he offered no introduction, greeting, or explanation. Eventually, he reached into a pocket and pulled out a coin. He tossed it to the street between them, and it bounced—metal ringing against stone—and came to a stop.

He jumped into the air. Vin did likewise, both Pushing against the coin. Their separate weights nearly canceled each other out, and they shot up and back, like the two arms of a "V."

Zane spun, throwing a coin behind him. It slammed against the side of a building and he Pushed, throwing himself toward Vin. Suddenly, she felt a force slam against her coin pouch, threatening to toss her back down to the ground.

What is the game tonight, Zane? she thought even as she yanked the tie on her pouch, dropping it free from her belt. She Pushed against it, and it shot downward, forced by her weight. When it hit the ground, Vin had the better upward force: she was Pushing against the pouch from directly above, while Zane was only pushing from the side. Vin lurched upward, streaking past Zane in the cool night air, then threw her weight against the coins in his own pocket.

Zane began to drop. However, he grabbed the coins—keeping them from ripping free—and Pushed down on her pouch. He froze in the air—Vin Pushing him from above, his own Push forcing him upward. And, because he stopped, Vin's Push suddenly threw her backward.

Vin let go of Zane and allowed herself to drop. Zane, however, didn't let himself fall. He Pushed himself back up into the air, then began to bound away, never letting his feet touch rooftops or cobblestones.

He tried to force me to the ground, Vin thought. First one to fall loses, is that it? Still tumbling, Vin spun herself in the air. She retrieved her coin pouch with a careful Pull, then threw it down toward the ground and Pushed herself upward.

She Pulled the pouch back into her hand even as she flew, then jumped after Zane, Pushing recklessly through the night, trying to catch up. In the darkness, Luthadel seemed cleaner than it did during the day. She couldn't see the ash-stained buildings, the dark refineries, the haze of smoke from the forges. Around her, the empty keeps of the old high nobility watched like silent monoliths. Some of the majestic buildings had been given to lesser nobles, and others had become government buildings. The rest—after being plundered at Elend's command—lay unused, their stained-glass windows dark, their vaultings, statues, and murals ignored.

Vin wasn't certain if Zane purposely headed to Keep Hasting, or if she simply caught up to him there. Either way, the enormous structure loomed as Zane noticed her proximity and turned, throwing a handful of coins at her.

Vin Pushed against them tentatively. Sure enough, as soon as she touched them, Zane flared steel and Pushed harder. If she'd been Pushing hard, the force of his attack would have thrown her backward. As it was, she was able to deflect the coins to her sides.

Zane immediately Pushed against her coin pouch again, throwing himself upward along one of Keep Hasting's walls. Vin was ready for this move as well. Flaring pewter, she grabbed the pouch in a two-handed grip and ripped it in half.

Coins sprayed beneath her, shooting toward the ground under the force of Zane's Push. She selected one and Pushed herself, gaining lift as soon as it hit the ground. She spun, facing upward, her tin-enhanced ears hearing a shower of metal hit the stones far below. She'd still have access to the coins, but she didn't have to carry them on her body.

She shot up toward Zane, one of the keep's outer towers looming in the mists to her left. Keep Hasting was one of the finest in the city. It had a large tower at the center—tall, imposing, wide—with a ballroom at the very top. It also had six smaller towers rising equidistant around the central structure, each one connected to it by a thick wall. It was an elegant, majestic building. Somehow, she suspected that Zane had sought it out for that reason.

Vin watched him now, his Push losing power as he got too far from the coin anchor below. He spun directly above her, a dark figure against a shifting sky of mist, still well below the top of the wall. Vin yanked sharply on several coins below, Pulling them into the air in case she needed them.

Zane plummeted toward her. Vin reflexively Pushed against the coins in his pocket, then realized that was probably what he'd wanted: it gave him lift while forcing her down. She let go as she fell, and she soon passed the group of coins she'd Pulled into the air. She Pulled on one, bringing it into her hand, then Pushed on another, sending it sideways into the wall.

Vin shot to the side. Zane whooshed by her in the air, his passing churning the mists. He soon bobbed back up—probably using a coin from below—and flung a double handful of coins straight at her.

Vin spun, again deflecting the coins. They shot around her, and she heard several pling against something in the mists behind her. Another wall. She and Zane were sparring between a pair of the keep's outer towers; there was an angled wall to either side of them, with the central tower just a short distance in front of them. They were fighting near the tip of an open-bottomed triangle of stone walls.

Zane shot toward her. Vin reached out to throw her weight against him, but realized with a start that he was no longer carrying any coins. He was Pushing on something behind him, though—the same coin Vin had slammed against the wall with her weight. She Pushed herself upward, trying to get out of the way, but he angled upward as well.

Zane crashed into her, and they began to fall. As they spun together, Zane grabbed her by the upper arms, holding his face close to hers. He didn't seem angry, or even very forceful.

He just seemed calm.

"This is what we are, Vin," he said quietly. Wind and mist whipped around them as they fell, the tassels of Vin's mistcloak writhing in the air around Zane. "Why do you play their games? Why do you let them control you?"

Vin placed her hand lightly against Zane's chest, then Pushed on the coin that had been in her palm. The force of the Push lurched her free of his grip, flipping him up and backward. She caught herself just a few feet from the ground, Pushing against fallen coins, throwing herself upward again.

She passed Zane in the night, and saw a smile on his face as he fell. Vin reached downward, locking on to the blue lines extending toward the ground far below, then flared iron and Pulled against all of them at once. Blue lines zipped around her, the coins rising and rising shooting past the surprised Zane.

She Pulled a few choice coins into her hands. Let's see if you can stay in the air now, Vin thought with a smile, Pushing outward, spraying the other coins away into the night. Zane continued to fall.

Vin began to fall as well. She threw a coin to each side, then Pushed. The coins shot into the mists, flying toward the stone walls to either side. Coins slapped against stone, and Vin lurched to a halt in the air.

She Pushed hard, holding herself in place, anticipating a Pull from below. If he pulls, I Pull, too, she thought. We both fall, and I keep the coins between us in the air. He'll hit the ground first.

A coin shot past her in the air.

What! Where did he get that! She'd been sure that she'd Pushed away every coin below.

The coin arced upward, through the mists, trailing a blue line visible to her Allomancer's eyes. It crested the top of the wall to her right. Vin glanced down just in time to see Zane slow, then lurch upward—Pulling on the coin that was now held in place atop the wall by the stone railing.

He passed her with a self-satisfied look on his face.

Show-off.

Vin let go of the coin to her left while still Pushing to her right. She lurched to the left, nearly colliding with the wall before she threw another coin at it. She Pushed on this one, throwing herself upward and to the right. Another coin sent her back upward to the left, and she continued to bounce between the walls, back and forth, until she crested the top.

She smiled as she twisted in the air. Zane—hovering in the air above the wall's top—nodded appreciatively as she passed. She noticed that he'd grabbed a few of her discarded coins.

Time for a little attack myself, Vin thought.

She slammed a Push against the coins in Zane's hand, and they shot her upward. However, Zane was still Pushing against the coin on the wall top below, and so he didn't fall. Instead he hung in the air between the two forces—his own Push forcing him upward, Vin's Push forcing him downward.
