The danger wasn't coming.
It was already there.
Hidden.
Silent.
Patient.
Earlier—
When the train had stopped—
Something had entered unnoticed.
Small enough to ignore.
Fast enough to disappear.
Now—
Its effect had begun.
A middle-aged woman sat three rows behind them.
Still.
Too still.
At first—
No one noticed.
Why would they?
Everyone's attention was fixed on the door.
On the noise.
On the fear outside.
But not his.
His instincts pulled his attention elsewhere.
Scanning.
Observing.
Looking for what didn't fit.
And something about her—
Didn't.
Her posture was rigid.
Unnaturally so.
Her hands rested in her lap—
But her fingers trembled.
Then stopped.
Then trembled again.
His eyes narrowed slightly.
A thin line of blood appeared beneath her nose.
Slow.
Dark.
No one else saw it.
Her breathing changed.
Subtle at first.
Then uneven.
Her chest rose sharply—
Then fell too slowly.
Her head dropped forward.
Then—
Snapped back up.
Too fast.
Too sudden.
The husband took a step forward.
Something was wrong.
Very wrong.
Behind him—
The wife shifted slightly.
Now fully awake.
Now aware.
But not understanding.
And then—
The woman screamed.
Not in fear.
Not in pain.
Something else.
Something broken.
Her body jerked violently.
Her back arched against the seat.
Her hands clawed at the air—
As if fighting something invisible.
"Help her!" someone shouted.
But no one moved.
Because everyone felt it.
That instinct.
That warning.
This wasn't something you could help.
This was something—
You needed to run from.
