Luca stopped going near the door.

  Not a decision. Decisions required the architecture of choice, the weighing of one direction against another, the moment of selection. This was not that. This was the body learning a route the way water learned a channel, by flowing around the obstacle enough times that the avoidance became the path itself.

  Windowsill. Work desk. Serena's side. The triangle of permitted space, its vertices defined not by walls but by the color of the person whose spectrum determined whether the air in the cabin felt breathable or thin. Windowsill: water-blue, stable. Work desk: wisteria, faintly stronger, the warmth of proximity. Serena's side: wisteria plus rose, the maximum safety the closed system could produce.

  The door: dark purple. White. The colors that meant where are you going in a voice too gentle for the question it was asking.

  So the body stopped going near the door. Not because the door was locked. The door was always unlocked. The latch was wood and Serena never barred it. The door was open and the body did not approach it, and the gap between open and accessible widened without anyone naming it.

  The grey of Luca's body had deepened. Not dramatically. A shade, maybe less. But the core's pulse, which had quickened during the honeymoon weeks, had slowed to a rhythm that matched something older. Not the cave's rhythm. Not quite. But closer to it than to the rhythm of the circuit that had, for a few weeks, made the grey look like something that might change.

  [Heal]'s light still moved inside the core. It had not weakened. But the intervals between its pulses had lengthened, the way the intervals between breaths lengthened when a body was conserving energy it did not expect to spend.

  ***

  The traveler was sitting at the edge of the road with his leg at an angle that legs were not designed to hold.

  Luca registered the colors before the shape. From inside the pouch, through fabric and warmth and the thirty-four degrees of Serena's body heat, [Emotion Sense] caught the signal. Pain-red, bright, arterial, the kind of red that bypassed complexity and went straight to the brainstem. Fear-white beneath it. And threaded through both, the formless color of a person reaching for help that had not arrived.

  The bat's broken wing. The rabbit's cooling body. The traveler in the ruins whose arm hung wrong. The same signal, the same frequency, received by the same core that had been built to answer it.

  [Heal]'s light surged.

  The pulse was immediate, reflexive, the circuit that connected damage detected to move toward it firing before any higher function could intervene. The light filled the core and pressed outward, reaching for the membrane, reaching for the surface, reaching for the source of the red signal that was pouring through the pouch fabric like heat through thin cloth.

  Luca pushed toward the pouch's opening.

  Half a second of hesitation. The body remembered the frost. The ground hardening. The membrane gripping the soil. The cold arriving from the same hands that had carried thirty-four degrees. The memory ran through the gel in a single contraction, a full-body flinch compressed into the time it took the pain-red to pulse once more from the roadside, and the flinch lost. [Heal] was older than the frost. [Heal] was older than the fear. The light pressed forward and the body followed and the membrane crested the lip of the pouch opening.

  Ice.

  Thin. A film across the mouth of the pouch, crystallized in the fraction of a second between Luca's movement and Serena's fingers tightening on the fabric. Not a wall. A membrane. Translucent, catching the afternoon light and bending it into a faint prismatic edge that reminded the core of something. The light of an ice lance, refracting through the clearing where a woman had killed four goblin-rats and crouched to place the back of her hand against the ground and offered a choice.

  That light had been salvation.

  This light was a seal.

  The pouch was dark. The pouch was warm. Thirty-four degrees, the temperature of the body that carried it, seeped through the fabric on all sides. Inside, [Heal]'s light had nowhere to go. It pressed against the ice membrane and reflected back, bouncing off the frozen surface and returning to the core, illuminating the interior of the pouch with a blue glow that had no exit. The core was bright. The space was bright. And outside the brightness, on the other side of the thin ice, the pain-red pulsed and pulsed and pulsed.

  "Leave him. I'll report it at the guild. Someone will come."

  The voice was calm. Reasonable. Factually correct. The guild maintained response teams for road incidents. Someone would come. The traveler's injury was a fracture, not a mortal wound. Waiting was the rational choice.

  [Emotion Sense] read the color beneath the voice.

  Dark purple. Dominant. The wisteria, which had been the base tone of Serena's spectrum for weeks, was absent. In its place, the purple that had arrived with Faye and deepened with the B-rank party and darkened with the frost. The purple of this is mine and you cannot have it. Not directed at the traveler. Directed at the possibility that Luca's [Heal] might touch someone who was not Serena.

  Voice, calm. Color, not calm.

  The gap had been a crack in the road with Faye. A fissure with the B-rank party. A fracture with the frost.

  Now it was a canyon.

  Inside the pouch, [Heal]'s light rebounded. Core to membrane to ice to core. The loop tightened with each reflection, the light growing not brighter but more compressed, more concentrated, the energy of a skill designed to flow outward being forced to circulate inward. The pressure was not pain. It was something worse than pain. Pain had a location, a shape, a duration. This was the sensation of a thing that needed to move being prevented from moving, and the prevention having no end point, no threshold at which the body could say enough and the pressure would stop.

  Kyle's voice surfaced. Not words. A color. The demand-yellow of use it, use it again, one more time, keep going. The memory of MP draining, the core dimming, the light being pulled out of him faster than it could regenerate. That had hurt. That had been the pain of too much going out. This was its mirror. The pain of nothing going out. Opposite directions. The same core, compressed from opposite sides.

  Stolen from its rightful author, this tale is not meant to be on Amazon; report any sightings.

  Use it and don't use it were different commands.

  They pressed the same place.

  The traveler's pain-red faded with distance as Serena walked on. The signal weakened, dimmed, and eventually dropped below the threshold of [Emotion Sense]'s range. Gone. The light inside the pouch had no target left to reach for. It slowed. It did not stop.

  ***

  Marco's eyes found the pouch before they found Serena.

  "Heard about the road merchant. Broken leg, nothing worse. Guild team got him sorted." He leaned against the counter. His tone was light. His eyes were not. "He'll be fine."

  Serena's response came with the voice of her public self, the flat controlled surface. "Good."

  [Emotion Sense] read the gap. Voice: mild relief. Color: dark purple, unchanged from the road. The purple had not receded. Hours had passed and the purple was still there, no longer a reaction but a resting state. The recovery time, which had been seconds with the ice-blue, minutes with Faye's encounter, an afternoon with the B-rank party, had now extended past measurability. The dark purple was not recovering. It was staying.

  Marco's gaze dropped to the pouch again. Lingered.

  "You know, Serena, you've had that slime on you every waking hour for weeks now." The lightness in his voice thinned. "Reminds me of how you were with the Silverwind party. And the Ashguard group before that. You'd get close to someone, and then closer, and then..."

  He paused. The pause was not for effect. It was the pause of a man choosing between saying something that might help and saying something that would certainly not be welcome.

  "You're doing it again, aren't you."

  Not a question. The inflection did not rise. Marco's colors, warm and dark and threaded with the faint red of a warning given in good faith, held steady. The same colors Luca had filed in the guild weeks ago. The same concern. Unchanged, because Marco was a person whose colors did not change, and in the closed system of Serena's orbit, that constancy was the only external reference point that still existed.

  Ice-blue. A flash across Serena's spectrum, there and suppressed in under a second.

  "Mind your own business."

  The words were the same as the guild. The voice was not. Lower. Harder. The flat surface had developed an edge, and the edge was the sound of a person hearing truth and responding to it as threat.

  Marco raised his hands. "Just looking out for you." He stepped back. The concern in his colors did not diminish. But his body withdrew, because concern without authority was concern without action, and Marco had no authority over the wall that Serena built and maintained and reinforced each time someone tried to look over it.

  Luca, in the pouch, filed the colors. Marco's: warm, dark, red-warning. Serena's: dark purple over ice-blue over nothing. Marco's had not changed since the first reading. Serena's had not been the same color twice in the same week.

  The external reference point walked away. The closed system remained.

  ***

  Night. Hearth. The same configuration. Fire, chair, floor, knees.

  Serena spoke to the flames.

  "That man on the road. He'll be fine. The guild took care of it." A pause. The wisteria surfaced. The angled wisteria, the one that meant hear this, the one that had replaced the room-addressed monologues of the first night. "But what if you'd healed him, and he'd wanted to keep you? People do that with rare variants. They take them. Sell them. Use them."

  The logic was not wrong. Variant slimes were valuable. Traffickers existed. The world outside the cabin was not safe for a creature half the size of a palm with a skill that humans wanted.

  "I just want to keep you safe."

  The tears came.

  Third time. [Emotion Sense] received the spectrum and ran the match against the archive. Grey-blue. White. Trembling wisteria. The same three colors as the hearth, as the frost, as every time Serena's fear surfaced and spilled.

  The same. Almost.

  The wisteria was thinner. The grey-blue was deeper. The white was wider. If Luca had been comparing the three instances side by side, the shift would have been visible: the warmth retreating, the fear advancing, the ratio changing by degrees so small that each individual instance looked like the one before it. The way a shoreline eroded. Not in dramatic collapses but in the accumulation of waves too gentle to notice and too constant to resist.

  But Luca was not comparing. Luca was receiving. The tears touched his [Emotion Sense] and the light in his core pulsed and the body moved toward the crying because that was what the body did when damage was detected, that was what it had always done, that was the thing he was built for.

  His body pressed against her knee.

  Serena's colors shifted. Grey-blue thinned. White receded. The trembling wisteria steadied.

  Third cycle. Tears, and then presence, and then the fear subsided.

  He had not healed the traveler. He had been inside a warm pouch with an ice seal over the opening while a man's leg bent at the wrong angle and his pain-red poured into the air and [Heal]'s light bounced off the walls of its cage and came back to the core with nowhere to go.

  Kyle had forced [Heal] out. Serena had forced [Heal] in. One drained the core. The other flooded it. Neither let the light go where the light wanted to go.

  I could have healed him. I was not allowed to heal him.

  The distinction between chose not to and was not allowed to. In the cave after Kyle, chose not to had been a wound. This was something else. The choice had not been offered. The light had reached for the opening and found ice.

  Serena slept. Her hand rested on Luca's body. In the firelight, the hand looked the same as always. Long fingers. Pale skin. The faint blue of veins visible beneath.

  From the pallet, in the deep unguarded hours, the murmur came.

  "...my... Luca..."

  The possessive, spoken in sleep. The word that had first appeared on the road with Faye, in the daylight, in the public voice. Now it surfaced again in the dark, in the unguarded voice, stripped of the pleasantness that the waking version wore. [Emotion Sense] received the sleeping colors: dark purple and wisteria, mixed, unseparated, the possessiveness and the affection occupying the same space without the consciousness that usually kept them in separate registers.

  Luca recorded. Too exhausted to process. The data entered the archive alongside the ice membrane and the pain-red and the three cycles of tears, unanalyzed, waiting for the day the archive would be opened and the pattern would emerge.

  ***

  Not the windowsill. Not tonight.

  The tears had pulled him back. The windowsill, which he had reclaimed after the frost, was across the room, and across the room was a distance that required separating from the knee, and separating from the knee required a decision that the body, synchronized at zero-offset and pressed against thirty-four degrees and wrapped in the residue of wisteria that had steadied when he stayed, could not produce.

  His position was controlled by tears. The frost had moved him to the windowsill. The tears had moved him back. His location in the cabin was a function of Serena's emotions, charted on a graph where the x-axis was Serena's distress and the y-axis was Luca's distance from her body, and the correlation was perfect, and the correlation was a cage.

  A cage.

  The word arrived without precedent. He had not called the frost a cage. The frost had been too close, too physical, too immediate for abstraction. But tears were not physical. Tears operated at a distance, through the medium of color and warmth and the reflex that connected someone is hurting to stay, and because they operated at a distance, the mind could see them from far enough away to give them a shape.

  The shape was a cage.

  Warm. Soft. And when he pressed against the walls from inside, they did not break. They gave, and gave, and held. The bars were not iron. The bars were the impossibility of saying stop crying to a person whose crying was real. The lock was not a key. The lock was [Heal]'s own reflex, the thing that made him move toward damage, turned against him by damage that he could not repair.

  The ice on the pouch had melted in minutes. The tears had not melted at all.

  Tears do not melt.

  The fire was embers. The cabin was dark. Serena breathed. Luca pulsed. The offset was zero. The grey body lay against the knee that had not moved and would not move until morning, in a cabin with an unlocked door that the body would not approach, on a floor where the triangle of permitted space had contracted by another vertex without anyone drawing a new line.

  Serena's tears were a cage. Warm and soft and impossible to break from the inside. You cannot tell a crying person to stop. You cannot leave a crying person alone.

  Tears are harder to melt than ice.

  Next time: Back to the dungeon, and Luca's [Heal] hits a wall.
