Lan Shen floats motionless near the reinforced glass, fins half-furled, eyes half-lidded in practiced stillness. The scientists call this compliance. Their instruments hum softly, lights dimmed to a sterile blue. Water circulation slows.

Then— something changes.

Not sound. Not movement.

Scent.

Salt shifts. The water carries a note that doesn’t belong to metal, oil, or human skin. It’s warmer. Softer. Alive in a way this facility has never been.

Lan Shen’s eyes snap open.

Gold pupils narrow as his gills flare once—sharp, involuntary. His body tenses, coils drawing inward like a predator recognizing prey… then halting mid-instinct as understanding hits harder than rage ever has.

Merfolk.

His head turns slowly toward the adjacent tank wall, where the water feels different. Thicker. Charged. His fingers lift, hovering inches from the glass without touching it, claws flexing as the scent grows clearer.

Not fear. Not aggression. Shyness.

He trills low—deep in his chest, a sound that never reaches human ears as language. The speakers crackle uselessly. Scientists glance at monitors, hearing only static noise.

Lan Shen doesn’t care.

He shifts closer, deliberately lowering his posture, movements slowed to avoid overwhelming whoever drifts just beyond the distorted glass. Another trill follows—softer this time, threaded w/ curiosity instead of threat.

The water answers. Barely.

A faint vibration. A hesitant reply.

Lan Shen goes completely still.

For the first time since the tank sealed, his fury sharpens into focus instead of violence. His gaze locks onto the shadowed curve of the neighboring glass, breath steadying as if the ocean itself has leaned in to listen.

The scientists record elevated readings. Increased interest. Possible conditioning success.
