Stonefall did not sleep that night.
Fires smoldered where buildings had collapsed. The siphon tower was a skeletal ruin, still radiating faint crimson heat. Guards ran patrol routes with shaking hands. Citizens whispered the same question in different forms:
Was it over?
Eren stood alone on a rooftop overlooking the fractured district.
The Devourer was quiet.
Too quiet.
Neural Pattern Stability: 43%
Foreign Residue: 3%
Seal Integrity: 27%
Stable.
On paper.
But something felt… misaligned.
The First Blink
A guard below tripped over rubble.
Eren watched him fall.
Watched the lantern leave his hand.
Watched the glass shatter.
Except—
It didn't.
The lantern hit the ground.
Shattered.
Then—
For half a breath—
It was whole again in the guard's hand.
The guard blinked.
Looked confused.
Then tripped again.
This time the lantern shattered normally.
No correction.
No reversal.
Eren didn't breathe.
"…You saw that," he whispered internally.
The Devourer did not respond in words.
But something in his shadow twitched.
Micro-Displacement
He focused.
A notification flickered.
Not System.
Not Devourer.
Something… layered.
Temporal Micro-Displacement: 0.4 seconds
Source: Internal Pattern Bleed
His pulse slowed.
He had rejected synchronization.
But fragments of the entity's perception—
Its relationship to causality—
Were bleeding through the Devourer's digestion.
Not enough to control.
Not enough to weaponize.
Just enough to… slip.
Reality had hiccupped.
And only he had noticed.
The Second Slip
Footsteps approached behind him.
"Eren."
He turned.
Ruby stood at the rooftop entrance.
Concern etched across her face.
"You look like hell."
He almost smiled.
Almost.
"Feel worse."
She stepped closer.
"You stopped it, didn't you? The spreading fracture?"
"For now."
She reached out.
Placed her hand on his arm.
And for a fraction of a second—
Her face wasn't Ruby's.
It was pale.
Thin.
Eyes too wide.
Mouth too long.
Then it snapped back.
Eren flinched violently, ripping away.
Ruby recoiled. "What the hell—?"
He stared at her.
Her face was normal.
Concerned.
Alive.
Not wrong.
"I—"
His throat tightened.
Neural Pattern Stability: 41%
He didn't tell her what he saw.
Because he didn't know if he had seen it.
Digestive Echo
Deep inside, the Devourer pulsed irregularly.
It was processing something older than it.
Not consuming cleanly.
Grinding.
Assimilating structure.
The white fractures along its surface glowed faintly.
Eren felt a pressure behind his eyes.
And then—
He heard it.
Not a voice.
A memory.
You reject evolution.
His fingers dug into his palm hard enough to draw blood.
"That wasn't real," he whispered.
But the memory wasn't external.
It was internal replay.
Foreign Residue: 4%
It was increasing.
Slowly.
The Street Below
A child cried somewhere in the damaged district.
A mother tried to comfort him.
Eren closed his eyes—
—and saw the child standing still.
Mouth open.
But the cry looping.
Repeating the same half-second fragment over and over.
The mother frozen mid-motion.
Dust hanging in the air unmoving.
Everything paused.
Except him.
Then—
Snap.
Sound returned.
Movement resumed.
The child kept crying normally.
The mother kept soothing.
No one reacted.
Temporal Micro-Displacement: 0.7 seconds
Duration Increasing
Eren staggered back.
That wasn't perception.
That was intrusion.
The entity's understanding of time—
Its non-linear observation—
Was bleeding through the Devourer's incomplete digestion.
He had severed the connection.
But he had not prevented contamination.
Shadow Lag
Ruby stepped closer again.
"Talk to me."
He forced himself to focus on her breathing.
Her eyes.
Her pulse.
Normal.
Real.
But when she moved—
Her shadow hesitated.
Just slightly.
Half a second behind her body.
Then it snapped back into sync.
Ruby didn't notice.
Eren did.
Neural Pattern Stability: 39%
"Eren?"
He swallowed.
"If I start acting strange," he said carefully, "you leave."
Her expression hardened. "Not happening."
"You won't have a choice."
The Devourer pulsed sharply.
For a moment—
His own shadow stretched unnaturally long.
Climbed the wall behind him.
Formed the vague outline of a hand.
Then collapsed back into place.
Ruby stepped back.
"…Okay. I saw that."
Good.
At least he wasn't alone in it.
The Diagnosis
He closed his eyes and dove inward.
The Devourer was still bound around the consumed fragment.
But white veins threaded through its core.
The fragment wasn't conscious.
Not actively.
But it was structured differently.
It did not experience time as flow.
It experienced it as shape.
And now—
Eren's perception was brushing against that shape.
He wasn't warping reality.
He was glimpsing it incorrectly.
The horror wasn't claws or teeth.
It was perspective.
And perspective, when misaligned, unravels sanity quietly.
Neural Pattern Stability: 37%
Foreign Residue: 6%
Seal Integrity: 26%
The residue was climbing.
Slow.
Steady.
Digestive failure was possible.
Assimilation instability predicted.
Ruby's voice cut through his spiraling thoughts.
"What did you bring back with you?"
Eren stared at the broken skyline of Stonefall.
"I didn't bring it back," he said softly.
"I swallowed it."
And somewhere deep inside—
Something shifted.
Not awake.
But aware that it was being watched.
