Remember to breathe. We may not have to, but you do, so use it. Strike on the exhale, it gives you more power. Great advice, but the trick was managing to land a blow at all, which was suddenly a lot harder. Parry, retreat, strike, lunge—I was moving on autopilot as Pritkin kicked it into high gear. I guess he'd decided playtime was over. And I hadn't even realized that was what we'd been doing.

Within a minute, the burn of tired muscles was working its way through my arms and shoulders, down to my spine. Sweat was dripping in my eyes, turning my vision hot and grainy, and an exhausted headache was building inside my skull. But Pritkin's sneaker-clad feet made hardly any sound against the polished wood floor, and he'd stopped telegraphing his movements. While the mirrors threw back images of him as an almost living extension of his weapon, his word flowing seamlessly into muscle and sweat and bone, I had to concentrate just to stay in the fight and not trip over my own feet.

There's no such thing as a fair fight! Use what you have, all you have: throw sand in their eyes, kick dirt, hit below the belt. Remember, your goal is survival, not a prize for chivalry. That last was one lesson, at least, that I'd never had to be told twice. I ignored the blade coming at me, concentrated on the space behind Pritkin, and shifted. A second later, I had the point of my sword in the small of his back.

I hesitated, foolishly assuming that would end it, but Pritkin apparently had other ideas. He whirled, his weapon catching mine and spinning it out of my hand, his sword point under my chin, all practically before I could blink. "I wondered how long it would take before you remembered you can do that."

I shifted before the look of amused superiority on his face had completely coalesced, and grabbed my sword from where it had skidded to a stop under the windows. I turned to find him almost on top of me, having crossed the room at a run, and I shifted again just before he got a hand on me. I tried something a little fancy, hoping to save the few seconds it would take me to turn around, and ended up facing him.

Unfortunately, my inner ears didn't appreciate the sudden change in direction and a wave of dizziness cost me more time than a spin would have. It also made me stumble into him as he started to turn and we tripped and went down to the floor together, trying to move our swords out of the way before we fell on them. I tried to pin him, but he rolled us over and grinned down at me, eyes bright, face flushed.

"That's thrice now, practically back to back. What's your limit again? Four?"

I shifted out from under him and heard him fall to the floor with a thump as I grabbed my sword back. Or maybe it was his; my hair was in my eyes, along with a lot of sweat, and I wasn't seeing too clearly. "It varies," I panted, denting the sweatshirt over his heart with the point. "On the motivation."

Pritkin's leg caught me behind the knee, and I stumbled, barely managing to move the sword before I impaled him with it. A hard body slammed me the rest of the way to the floor before I could recover, and warm breath was in my ear. "You're not sure?"

"Haven't had reason…to find out yet," I said savagely, trying to buck him off. Of course, it didn't work.

"It's a good trick," Pritkin said, not letting me up, "but of limited use if it's the only one in your arsenal. We're going to have to work on—"

I gave a final heave, and when it had no more effect than the others, shifted once more. It was perceptibly harder this time, and the dizziness on landing was a lot stronger. I'd aimed for the far side of the room, but by the time I recovered, Pritkin was almost there. "Enough, already!" he yelled. "Making yourself sick isn't going to—"

"You're just…a sore loser," I panted, trying to get my breath back. Shifting the first time had been like running up a couple of stairs; this one had felt more like ten flights.

"I wasn't aware that I had lost," he replied, sword point getting friendly with my ribs. But he wasn't taking me seriously, wasn't watching my body language, probably expecting me to shift again. So I didn't.

A twist and a step took me inside his reach, the pommel of my sword caught his chin and my foot hooked around his ankle. With a pull we were on the floor again, but this time I was on top, with a wooden blade against his neck. He made a choked noise of surprise, or maybe it was protest over the fact that I had pressed a little too hard. It wasn't enough to break the skin, but it left a mark, red and raw-looking. I rolled off, my heart threatening to pump out of my chest, my legs rubber.

I leaned back against a mirror, chest heaving. I would have liked to gloat, since I'd likely never have the opportunity again, but I didn't have enough air. "I win. So talk."

"What would you like to hear?" he asked, sitting beside me. His tone was even—the bastard wasn't even breathing heavily—but he dragged the sword point across the floor hard enough to scratch the wood. "That that creature forced himself on my mother, knowing she would die in childbirth like the hundreds of other women he'd assaulted? That only the small amount of Fey blood she possessed gave her the strength to survive until their child was born? That I exist solely because of his perverse curiosity to see if such a thing was even possible?"

I blinked. I'd had a mental list of arguments lined up to talk him into telling me something, all of which now had to be trashed. The one thing I hadn't expected was for him to just come out with it like that, with no embarrassment, no twitching. And therein lay the problem with every single conversation Pritkin and I had ever had.

I was used to the way vamps quarreled, in convoluted, subtle conversations, a dance of lies and hidden truths, more silent than spoken. I knew that dance, those steps. But with him, there were no convoluted discussions, implied threats or discreet bargains, just blunt statements of fact that left me oddly confused. I kept looking for the hidden meaning when there wasn't one. At least I hoped there wasn't.

"I'm beginning to understand why you hate demons," I finally said.

"I hate demons because they exist solely and utterly to plague humankind! They have no redeeming qualities—they are pests at best and scourges at worst—all of which should be hunted down and destroyed, one by one!"

"You're saying that in an entire race there isn't one good—"

"No."

I knew what it was to grow up feeling that something important was missing from life, to have no reason to mourn people I never knew, yet to feel their absence like an ever-present ache. Pritkin certainly had reason to hate Rosier, maybe even demons in general, but I thought genocide might be taking things a little far. "And you've met them all?" I asked, trying not to flinch under that burning green gaze.

"You grew up with vampires," Pritkin said savagely. "Would you care to guess where I spent my formative years?"

A little late, I remembered Casanova saying something about Pritkin being thrown out of Hell. I'd assumed he was exaggerating. Or not, I thought, as Pritkin jumped up and began pacing, his face redder than when we'd finished practice.

"You grew up with those creatures, yet you defend them! I have never understood that, how any human could align herself with the very beings who feed on her!"

"You're confusing demons and vamps again." He'd had that problem all along, and living around Casanova, the only incubus-possessed vamp, probably hadn't helped.

"Am I?" Tension radiated from his body, and his mouth tightened to its usual downturned line. "They're self-centered, morally bereft predators who feed off any humans foolish enough to give them the chance. I fail to see a great deal of difference!"

I was beginning to understand why Pritkin had never been a big fan of vamps. The way they and incubi fed might seem a little too close for comfort. Vamps took blood, while incubi fed directly on the life force itself, accessed through the emotions. But the distinction might get a little blurry for someone with his background.
