Open up. I’m the train assistant

*Thirty minutes before the train stopped.*

Under the crystal's glowing light, two hooded men stood up. One of them held up two fingers to the other, who nodded and moved left, passing the public bunk bed.

One of the masked men approached the glowing crystal displayed out in the open.

He pulled goggles from his pocket and put them on, signaling for his partner to do the same.

Then, he covered the crystal with a thick blanket, instantly plunging the space into darkness.

"Who covered the crystal?!''

"Turn it back on!''

"Don't joke around—people are pre—Ghhk…gurgle…khhrrgh….ugh…'' The woman's voice was cut off by muffled choking sounds.
