The Kindness of Poisons

Summary:

Katara has completed eight jobs for Hama. The ninth is a Fire Nation prince with gold eyes and the inconvenient habit of asking if she's all right like he means it. She has six weeks. Her brother has four. The math only goes one way.

It was supposed to be simple.

Notes:

Assasin fics were mentioned in Zutara Reddit, and the muse took over from there really.

Chapter 1: The Last One

Chapter Text

The mirror was small and age-spotted. In it, Katara could see the pale rectangle of light falling from the narrow window cut into the roof.

Katara sat with her spine straight and her hands loose in her lap while Hama moved behind her, unhurried as ever.

On the small table to her left sat two vials. One dark. One clear. Katara knew them by shape now. Beside them lay small pots, brushes, a folded square of black cloth, and a lantern burning at the table’s edge.

Hama’s fingers worked oil through her hair first. Starting at the ends, she pulled and twirled the strands into tight spirals before she let them rest, letting them unwind with gravity.

The smell of the oil hit before the touch: fire lilies, thick and sickly sweet. The kind of scent that sat at the back of the throat and stayed there. Katara’s eyes prickled. She pressed her tongue to the roof of her mouth and held back the sneeze, but the itch lingered. Crawling up her throat to somewhere behind her eyes. In the mirror her eyes had gone glassy and bright.

Hama didn’t comment. Watery eyes were nothing new around her. 

When the last strand had been worked through, Hama set the bottle down and reached for the comb.

Something in Katara went very still.

The comb was bone and shell, carved in the Southern style. Katara had known it since she was small enough that the sight of it meant her mother settling behind her just like this, in better light, in a room that smelled of salt and open water. Not fire lilies. Not sealed stone. Not the faint, bitter edge of whatever Hama kept in the vials.

She had asked, once, how Hama came to have it.

The slap had snapped her head sideways. Hama’s nails had caught her jaw on the backswing and the gash had wept for hours, and her tears had made Hama smile in that particular way she had. Slow. Satisfied. 

Katara learned two things that day. The comb was not a subject. Tears cost more than they were worth. Hama collected them.

She had learned not to question Hama at all. She saved her tears for when she was alone. Or for Sokka, on the rare occasions Hama allowed her to see him.Those brief supervised minutes that were less a kindness than a reminder of what obedience bought. She had learned to read him fast. Whether he was eating. Whether he was sleeping. Whether the thing behind his eyes was still him.

She watched the pale light on the floor and sat still.

“The Fire Nation court expects softness from a lady,” Hama said, pulling the comb through a tangle. “Give them softness, and they won’t look for anything else.”

“I know.”

“You’ll be selected at the first viewing. I’ve made sure of it.”

Hama set the comb down and met Katara’s eyes in the mirror. The face that looked back was a grandmother’s face. Soft-jowled, white-haired, the kind of face that belonged in a kitchen or a sickroom. 

But the eyes were wrong. Pale blue, almost colorless, sunken deep beneath the shelf of her brow. Glacial. Her thin lips didn’t move but something in those eyes did, a slow tightening, and the message was as clear as anything Hama had ever said aloud: Don’t move. 

Then her gaze dropped, her attention returning to the hair in her hands, fingers dividing and sectioning without hurry.

Katara sat still. 

In the mirror, Hama’s hands sectioned and pulled, winding the braid up and back in the unfamiliar style. The pins came next, sharp little bites at her scalp. Katara’s jaw tightened. A small hiss escaped her once, when Hama pulled a section too tight, but Hama’s hands didn’t slow.

“Pay attention,” Hama said. “Once you’re inside, no one else can do this for you.”

Katara winced at another sharp tug, but still watched. She catalogued the sections, the tension, the placement of each pin. The style swept up at the temples and left the nape exposed. Fire Nation. Court style.

Hama reached forward and opened one of the small containers. “Watch,” she said, and loaded the brush with the particular economy of someone who had done this many times on many faces. “Light at the cheekbone. Heavier at the lid. The mouth last.” The color went on in strokes. Painting Katara’s cheeks, the bow of her lip, the corners of her eyes in something dark that made them look larger and more liquid than they were. “The effect is softness. The technique is precision. One without the other reads false.”

“I’m watching,” Katara said.

Another container. A different brush. Hama tilted Katara’s chin up without asking. Katara let herself be tilted, her eyes tracking everything in the mirror. The layering. The order. Hama’s smallest finger blending at the temple.

In the lantern’s warm light, she looked like something that had bloomed there by accident.

“You’ll practice before the viewing,” Hama said. Not a question.

“Yes.”

“There,” Hama said, behind her, to the mirror. It was almost the worst part, every time. Looking at the finished thing and recognizing it as herself.

Hama set the brush down and reached for the dark vial.

Hama removed the stopper and moved to Katara’s side. Katara held out her arm without being asked.

This, too, she had learned.

The needle was small. Hama had a gift for small things: small pains, small cruelties, small corrections. The poison entered her bloodstream with almost no sensation. Just a prick of cold, travelling up from the puncture site like snowmelt through stone.

Hama set the dark vial down. She picked up the cloth and pulled out a third vial. Smaller than the others, the glass clouded pale, and held it briefly to the lantern light before setting it on the table beside the clear one. "Persuasion," she said, in the same tone she used for weather. "One drop in something warm. It won't harm him." A pause that contained no kindness. "Just makes the evening easier. Use it if the access requires it. Don't use it otherwise."

Katara looked at the three vials. Dark. Clear. Clouded pale. Poison. Antidote. Persuasion.

Hama had always liked giving things clean names.

“How long?” she asked, eyes trained on the floor.

“Six weeks from today. After that, the compound binds too deeply. The antidote must be administered before then.” Hama set the vial down and faced her.

“Complete the job. Come home. This ends.”

Katara met her eyes. “You’ve said that before.”

“I mean it this time.”

She had said that before, too.

Hama adjusted the collar of Katara’s robe with two fingers. A precise, maternal gesture. Then her thumb brushed Katara’s cheek, her skin dry and papery, like the texture of old maps. Katara kept her eyes on the pale edge of light on the floor and felt nothing. 

“You’re my finest work,” Hama said. Not proudly. But as an assessment, not affection. “The prince won’t know what touched him.”

Katara nodded once.

Hama picked up the clear vial, the antidote, and held it to the lantern light. The gesture was almost contemplative.Something almost contemplative in the gesture. Then she set it down and said, flat and factual as weather, “Your brother’s last dose bought him another month. Complete this, and he gets the rest. All of it.” A pause. “No more counting.”

The room seemed to lose its air.

Katara looked at the clear vial on the table. 

She had suspected. Hearing it plainly was its own kind of violence and temptation. Not sharp. Heavy.

She tucked the emotions away, putting them with all the other things she couldn’t survive feeling.

But how could she deny the flicker of hope? After all these years. So she let it burn, but, guarded. No where Hama could see it on her face and twist it. It was hard. Freedom now close enough to touch. Close enough to be another trap, spoke the logic of past hurt.

“When do I leave?”

“Tomorrow.” Hama folded her hands. “His name is Zuko. He is twenty. Your age. The court is pushing for an heir to stabilize succession after—” a brief pause that was the closest Hama ever came to delicacy, “—recent events with the sister. He has no wife. The concubine arrangement is traditional. You’ll be presented in a viewing with four others and you’ll be selected and from there you’ll have access.”

“Method?”

“Your discretion. You have the compound. A cut, a drink, whichever serves. He doesn’t need to suffer, Katara. I’m not asking for suffering.” She said this as though it were kindness. As though the distinction mattered from the receiving end. “Quick and clean and then you come home. Both of you.”

Katara nodded.

“Get some sleep,” Hama said, already turning away. “You set out at dawn.”

At the door, Hama paused. Her shadow stretched long across the floor, swallowing the pale rectangle of light.

Then she left.

Katara did not sleep.

She sat on the edge of her cot and watched the moon crawl across the roof window. Six weeks. Four for Sokka. The math began without her permission. She ran through the job as she had been taught. Clean. Clinical. The mark was reduced to variables: access, method, timeline, exit. She had done this eight times before. The math always worked if you kept it math.

She checked the small container at her wrist. The compound, sealed, undetectable. She pressed her thumb against its small, solid weight and thought of Sokka in whatever room Hama kept him, counting his doses, trying not to count his doses.

When he was afraid, he used to count other things instead: knives on the wall, fishhooks in Gran Gran’s basket, the number of times he could make Katara roll her eyes before she cracked and laughed.

Hama had taught him better.

Six weeks for her. Four for Sokka.

Hama had always liked giving people different deadlines. It made desperation tidy.

The math only worked one way.

Prince Zuko. Twenty years old. A throne come to him bloody and sideways through a tragedy she had been briefed on in flat, factual terms: Ozai dead, Azula somewhere no one named directly, a succession crisis cracking the Fire Nation down the middle. 

She moved on.

This was the last one.

She almost believed it.

She lay down and watched the moon finish its crossing and disappear. Then she watched the dark ceiling and waited for dawn.
