The shoes were white, soft-soled, and they crossed the sliver of light without hurry, the way a person walks into a room they own. Dr. Mack came through the door with her lab coat open over the silk blouse, her hair still pulled back in that severe bun, and she was carrying nothing in her right hand and a syringe in her left, the needle capped, the plunger still. Behind her, Renata reached past the doorframe and pulled the door shut, and the latch clicked soft into the wood.

The room got smaller. Tyler felt it happen — the walls pulling in a half-step, the lamp's pool of light shrinking to the circle of floor between his shoes and hers. He kept his hands on the worn arms of the chair, exactly where they'd been, because Renata had told him not to move and because moving now felt like it would cost him something he couldn't see the price of yet.

Dr. Mack stopped in front of him, close enough that he could smell the antiseptic on her hands under the mint of whatever she'd washed with, and she held the syringe up at his eye level. The barrel caught the lamplight and threw a thin white line across the wall. She turned it slowly, once, so he could see the whole of it — the graduation marks, the pale fluid inside, the capped needle — the way you'd show a child a thermometer before you put it in their mouth.

"This is the waiting room," she said.

Her voice was the same soft clinical monotone it always was. She could have been reading a chart. She could have been telling him to open wider.

"For what's next. You understand that by now, I think. You've understood it for a while." She let the syringe rest at his eye level, not lowering it, not moving it toward him. "Which means this is the last chance you get to walk out of here. The side door opens from the inside if I unlock it. Renata will walk you to your car. You'll drive home, you'll keep the molar, you'll keep the two hundred and forty dollars, and you'll never hear from either of us again."

Behind the chair, the worn wood creaked once. Tyler didn't turn his head, but he felt her there — Renata's hand coming to rest on the top rail of the chair back, just above his shoulder, the wood warm under her palm where his own body heat had been soaking into it for the last twenty minutes. Her fingers curled over the edge. She didn't say anything. She didn't need to.

"That's the offer," Dr. Mack said. "I want you to hear it clearly, because I don't make it twice."

The lamp hummed. The fluorescent tube out in the corridor hummed at a different pitch, and the two sounds lay on top of each other and made a third sound that Tyler couldn't name. His jaw ached — the deep bone ache, the one that had started after the root canal and never fully left, the one that felt less like pain now and more like a tooth that had an opinion about him. He could feel his pulse in it. He could feel his pulse in his thumb, too, where it rested on the arm of the chair, tapping once against the wood and stopping.

"If I walk out," he said, and his voice came out lower than he expected, "what happens to the chart."

Dr. Mack's mouth did something at the corner. It wasn't quite a smile. It was the shape a smile makes before it decides to commit.

"The chart stays," she said. "Charts always stay. That's what charts are for."

She uncapped the needle.

The sound was small and sharp — a single clear click of plastic against plastic — and in the damp still air of the little room it landed like a dropped fork on tile. Tyler's eyes went to it without his permission. The needle was thin and bright and it held a bead of the pale fluid at its tip that caught the light and didn't fall. Dr. Mack held it up between them, angled so he could see it, and she let the moment sit there with the bead trembling on the point.

"Here's what I'll tell you," she said. "If I inject you, you're committed. I won't tell you to what. I won't tell you how long. I won't tell you what happens after, or where, or who's there. You'll find out the way you found out about the chair — by being in it." She turned the needle a fraction, and the bead slid along the point and stayed. "If you don't want that, say so now, and Renata walks you out, and we're done. I'll even refund the two-forty."

Behind him, Renata's fingers tightened on the rail. It was a small thing — the wood creaked, the knuckles went pale, and then the grip eased again — but Tyler felt it travel down through the chair and into his back like someone had pressed a thumb between his shoulder blades. She wasn't supposed to say anything. He understood that now, in the flat place under his ribs where the answers lived. Whatever she thought about this part, she didn't get to say it.

He looked down.

The stain was still there, under the front leg of the chair, dark and old and edge-less, part of the floor now the way a scar is part of a face. He looked at it for a long time. He thought about the last patient — the one who'd asked the same question he'd asked, the one Dr. Mack said he was already better than. He thought about the lower brackets on the dental chair back in the other room, the two that had stayed open, waiting for a Friday that hadn't come yet. He thought about his keys in her drawer and his shirt in her drawer and the way he'd driven an hour and eleven minutes at dusk with the sun going down behind him, having already decided, having decided a long time ago and only now catching up to it.

He thought about the turnout, and his own hand, and the fact that he'd locked all four doors and then unlocked them to drive home.

"I'm not leaving," he said.

Dr. Mack didn't gloat. She didn't soften. She simply brought the syringe down to his forearm, and she pressed the cool barrel of it flat against the inside of his wrist, just below the crease of his elbow, where the vein ran blue under the pale skin. The metal was cold and the cold was a fact, the first clean fact of the whole night, and Tyler watched it sit there against his arm without breaking skin, the needle angled away, waiting.

"Say it again," she said.

"I'm not leaving."

"Good boy," she said, and her porcelain teeth showed, even and white and not quite reaching her eyes, and she turned the needle in and slid it home.

It didn't hurt the way he expected. There was a pinch, a small bright sting, and then the strange deep pressure of something going into a place that wasn't meant to have anything in it. He watched her thumb find the plunger. He watched her press it down, slow and even, the way she did everything — the way she'd written in his folder while he walked out of the room, the way she'd said long charts are the ones that stay. The pale fluid went into him in a thin cold line that he could feel travel up his forearm and into the crook of his elbow and then vanish into the rest of him, and his jaw, which had been aching for days, went quiet all at once, like a radio switched off in another room.

Dr. Mack withdrew the needle and capped it and set it on the cart without looking at where she put it, and she stepped back half a pace, and she folded her arms, and she watched him the way she watched a chart.

The room began to go soft at the edges.

It wasn't like the other times. The other times had been a flood, a heat that came up through his chest and took the fear out of him and left him pliant. This was slower and quieter. This was the lamp dimming even though the lamp didn't dim. This was the hum in the corridor getting further away and the hum of the lamp getting closer, and his hands on the arms of the chair feeling like they belonged to someone sitting very near him. He tried to move his thumb against the wood and it moved, so that was something. He tried to lift his head and his head lifted, slow, and the room tilted a half-degree and settled.

"How long," he said, and the words came out thick.

"Long enough," Dr. Mack said.

Renata's hand left the rail. He heard her scrubs whisper as she moved around the side of the chair, and then she was in front of him, between his knees, and she was going down — not kneeling the way you kneel in church, but folding, easy, like she'd done it a hundred times, her ponytail swinging forward over her shoulder and her green eyes coming up to his face as she settled onto the floor at his feet. She put one hand flat on his thigh. She looked at him, and then past him, at Dr. Mack, checking, the way you check with the person in charge before you touch anything that belongs to them.

Dr. Mack nodded once.

Renata's hands went to his belt.

His jeans were still the same worn jeans, the button already loose from the drive, and she had them open in two movements and pulled down past his hips, and the cool air of the room hit his skin and made him shiver, and then her mouth was on him and the shiver turned into something else. She took him in without preamble, without teasing, her lips sliding down the length of him and her tongue flat along the underside, and Tyler's whole body jerked against the chair and his hands came up off the arms before he remembered and put them back down.

"Hands," Dr. Mack said.

He put them back on the arms of the chair. The wood was warm where he'd been gripping it. He held on.

Renata worked him slow and thorough, her mouth wet and hot and her hand wrapped around the base of him, and the drug was moving through him in a long slow tide that made everything happen at half speed and twice as clear. He could feel every inch of her tongue. He could feel the ridge of her teeth just behind her lips and the soft press of the roof of her mouth and the way her throat opened when she took him deeper. She hummed — she actually hummed, some low tune with no shape to it, the same way she hummed when the drill was running — and the vibration went up through his cock and into his stomach and made his breath catch in his chest.

"Look at me," Dr. Mack said.

He looked at her. She was standing where she'd been standing, arms folded, lab coat open, watching Renata's head move between his legs with the same flat attention she gave a chart. She wasn't aroused. She wasn't anything. She was taking it in, filing it, the way she filed everything, and Tyler understood with the part of him that was still clear that this was the part she liked — not the act, the record of it. He was being written down.

"You're doing well," she said. "You were always going to say yes."

Renata pulled off him with a wet sound and looked up, her lips swollen and shining, and she smiled at him — the real smile, the girl-next-door one, the one that had walked him through the front door in the first place — and then she took him back into her mouth and went down further than before, her hand working the base of him in time with her mouth, and Tyler's hips came up off the chair and she took it, took all of it, her throat working around him and her eyes watering and staying on his face the whole time.

The room was going soft again. The lamp was a smear of tea-colored light on the wall and the stain under the chair was a dark shape at the bottom of everything and Renata's mouth was the only sharp thing left in the world. He could feel it building — the long slow pull from somewhere behind his balls, up through his cock, gathering at the base and tightening, and he tried to say something, tried to warn her, and what came out was her name.

"Renata—"

She didn't stop. She took him deeper and her hand tightened and she hummed again, and Dr. Mack said, from somewhere above him, in that same soft clinical monotone, "Go ahead."

Tyler came into Renata's mouth.

It went through him in a long roll, his whole body pulling tight against the chair and his hands white on the arms and his heels digging into the floor, and Renata stayed on him through all of it, her throat working, swallowing, and when he was done she pulled off slow and wiped her mouth with the back of her wrist and looked up at Dr. Mack for the next instruction. A thin line of him was still on her lower lip. She didn't wipe it away.

Dr. Mack uncrossed her arms and looked at her watch.

"Good," she said. "Clean him up."

Renata reached for the folded towel on the seat beside Tyler's thigh — the clean white square, the one that had been sitting there the whole time, waiting — and she used it on him, gentle, thorough, the way she did everything. Tyler watched her do it from very far away. The drug had him now, all the way down, and the room was dimming at the edges the way a room dims when you're falling asleep in it, and the last thing he saw clearly was Dr. Mack picking the capped syringe up off the cart and dropping it into the pocket of her lab coat, and the last thing he heard was her voice, soft and unhurried, saying something to Renata that he couldn't quite hold onto.

Then the chair was holding him and the stain was under the chair and the lamp was the only light left in the world, and Tyler let his eyes close.
