The Rescuer Who Was Supposed to Die

Jang Yura did not cut the cable tie all the way off. The severed end of plastic stayed on my wrist and scraped my skin every time I moved. She left it visible on purpose.

"You said 07:08."

"That's the gas ignition time."

"Location."

"Sector B ventilation control room."

"Are you certain?"

I let a beat pass before answering. The timing had already collapsed once. Certainty was a luxury now.

"I read it in a record. I didn't see it myself."

Jang Yura pushed open the inspection door behind the staff restroom without taking off her medical gloves. The door swung halfway and stopped. An electric cleaning cart sat wedged inside at an angle. It was an obstacle that had never been in the original report. A janitor had pushed the equipment out during the evacuation announcement and abandoned it there.

I moved a person, the person moved the equipment, the equipment blocked the passage.

Jang Yura looked at my face once.

"Did you calculate this too?"

"No."

"Then push."

We shoved the cart aside. With my wrists bound, it was hard to put real force into it. Jang Yura didn't curse. She repositioned my shoulder instead.

"Legs, not your back. If you're good at counting numbers, count the rhythm too."

We pushed on three. The wheels cleared the groove in the floor. Hot air spilled out from inside the inspection door. A thin, faintly sweet smell threaded between metal and dust. Gas.

The ventilation control room was quieter than I expected. In my memory, the Sector B gauge panel should have shown the needle in the red just before runaway. Right now Sector B pressure trembled inside its normal band. Instead the lower Sector C gauge was climbing slowly.

I reached for the Sector B shutoff lever.

Jang Yura slapped the back of my hand.

"What did you just see?"

"Sector B is where it originally blew."

"Not originally. Now."

She dropped to one knee and held the back of her hand against the gap in the vent cover. The air was being drawn in through Sector C, not Sector B. My memory hadn't only gotten the time wrong. The location had moved down too.

A cough came from behind us. A man in gray work clothes came up from the bottom of the stairs. Dust lay thick on his helmet, and a name tag reading O Gyeongtae hung crooked from his chest pocket.

"Don't touch that lever. Close it now and the gas pools on the level below."

Jang Yura asked at once.

"Are you facilities?"

"I've been taking the blame for every loose screw in this station for twenty-seven years. I don't know what you're trying to stop, but Sector B is the wrong leg to stand on."

O Gyeongtae took out a flashlight and opened the filter housing. Orange dust clung to the filter surface. He rubbed a little between his fingers, smelled it, and made a face.

"That's not tunnel dust. Looks like ground-up reinforcement material. Somebody left the construction passage open down there."

"Construction passage?"

"The ventilation shaft that runs toward the old barrier wall. The maps say it's sealed. Work off the maps and the machines start sulking."

O Gyeongtae said it like a joke, but his hands were fast. He lashed the Sector B lever in place with a cord and bent toward the Sector C damper. The newest control screen showed nothing but an error. He didn't look at it. He knocked on the manual shaft in the side wall instead.

"Full shutoff and it blows. You have to close the two dampers in alternation. Forty second intervals. Block it too long and the cleaners down below suffocate."

"Cleaners?" Jang Yura reacted immediately.

"There was a cleaning cart back there. One of them may not have gotten out."

I checked my watch. 07:02. Six minutes to ignition, by memory. The location had already gone wrong, so the time could have shortened too.

"We need to check lower Sector C first."

Jang Yura cut the cable tie off my wrist completely. It wasn't a release, it was an instruction to use it as a tool. She pressed the cut plastic into my hand and said:

"Count the time. If you're wrong, say so right away."

"I will."

"Hide it and I drag you out."

O Gyeongtae snorted.

"Young people these days sign contracts before a rescue?"

"Because people don't keep their word if it's only spoken."

The short exchange pressed the tension down a little. It didn't press the time down. We went down the tunnel-side passage. Lower Sector C wasn't filled with smoke but with transparent heat. You could see the shape of the air shaking. A janitor's reflective vest lay on the floor.

Jang Yura lowered herself first.

"Make noise. If you're there, hit the wall."

There was no answer. Between the sounds of the ventilation fans I heard metal scraping. Behind the pipes on the left. A position that wasn't in my memory. Jang Yura followed my eyes and moved at once. She reached in between the pipes and cut the caught vest strap with her knife.

The janitor's upper body was pinned between the pipes. He was conscious but couldn't speak. Jang Yura supported his neck and opened his airway first.

"Mr. O, the oxygen is dropping in here."

"I know. That's why we hurry. Han Igyeom, was it? You with the numbers, count the seconds."

I looked at my wristwatch. It was 11 seconds off from the network clock. I don't know which one was right. Still, there had to be a single reference. I chose the second hand on the analog pressure gauge mounted to the wall.

"Closing the first damper. Three, two, one."

O Gyeongtae pulled the lever. The airflow inside the passage changed direction. Jang Yura worked the janitor's arm free. The man coughed and dug his nails into the floor.

"Twenty seconds."

"Not yet!" O Gyeongtae shouted. "You close it when you see the pressure drop. Work off a timetable and the machine kills the man."

I shut my mouth and watched the panel. The needle fell one mark, then jumped back. The 07:08 in my memory was reference material now. The gauge in front of me had taken command.

"Now. Second damper."

O Gyeongtae pressed the second lever. Jang Yura pulled the worker out by the waist. His shoe snagged on a pipe. I pushed the pipe with my knee and cut the shoelace. Orange dust came off on my hand. The texture was coarse and dry.

The flame didn't arrive like an explosion. At the end of the tunnel a blue light folded over once, and a short pressure wave shoved down the passage. The heat vented out between the lower Sector C dampers, not the sealed Sector B side. The direction bent so the wind didn't come at us.

Jang Yura went flat on the floor with her arm wrapped around the worker's head. I held onto the gauge panel and braced. O Gyeongtae didn't let go of the lever. An old scar stood up white on the back of his hand.

After the pressure wave passed, the passage was still there. A few wall tiles had come down and one filter housing was crushed, but the door was open. We had avoided the large explosion. Three fewer of the original dead.

Jang Yura checked the worker's breathing and asked me:

"Is this man on the list of the dead too?"

I took the receipt out of my pocket. I still didn't have the original list. In the rows of the dead in my memory, Jang Yura's name was the clearest, and the janitor was near the bottom of the record. Sector B fire fatality. The name was blurred. It wasn't a list I had seen myself, it was an incident summary table.

"He was in the record. The name isn't certain."

"Then say it isn't certain. In front of the person."

I turned my head toward the worker. He lay on the stretcher and only blinked.

"I don't know your name. In the original record there was a fatality in this section. Right now you're alive."

Only then did Jang Yura look at my wrist. The mark where it had been bound was red. She didn't apologize. She pulled gauze out of her medical pouch and tossed it instead.

"Wrap it. It's a nuisance if the skin tears the next time I tie you."

O Gyeongtae laughed, then coughed.

"You're both charmers. This station could come down and I still wouldn't be bored."

When we came up to the temporary triage area, the rescue headcount board had been rewritten. While Jang Yura checked the numbers, I scanned the incident log left on the station terminal. Sector B normal. Ignition at lower Sector C. Reason for ventilation direction change, blank. Orange dust sample required.

And beside the list of rescue targets was Jang Yura's name.

Original timeline fatality. D-27, Myeongjin Station. 06:53.

A living Jang Yura was stripping off her gloves in front of me. The mechanic's blood and the orange dust were mixed together on her fingers. I drew a line on the back of the receipt.

Jang Yura scheduled death. Result X.

Sector B ventilation explosion. Location X.

Gas ignition time. Partial match.

Jang Yura took my notebook away. Her eyes stopped on the letters.

"Why is my name here?"

I sorted what I could say from what I must not. If I said regression, she wouldn't believe me. And if she did believe me, a bigger problem started. All I had so far wasn't evidence, it was a memory that had begun to be wrong.

"You were scheduled to die today."

"Scheduled?"

"According to the record."

She didn't close the notebook. She didn't tear it either. She looked a long time at the words 06:53 death written beneath her own living face. Then she didn't give it back.

"From the next rescue on, we look at this together."

"It's dangerous."

"Hiding my own death record from me is more dangerous."

The station announcement declared the secondary incident closed. I checked the time of the announcement. 07:06. Two minutes earlier than the original ignition. Jang Yura put the notebook in her chest pocket.

Even after saying that, she didn't ask right away. First she repositioned the stretcher. She turned the janitor's head toward the outside of the passage and hooked the remaining oxygen tank up to the mechanic. Treatment came before questions.

That order made me uncomfortable. To me the unanswered question loomed larger, and to her the person still struggling to breathe came first. The list from the original timeline had organized the dead one line at a time, but the Jang Yura of the present started by changing the direction a person was laid down in.

O Gyeongtae held the filter bag out to the station incident commander.

"Throw this away and later you'll all blame the computer again. Seal it. Write the date, and write who picked it up."

The commander frowned.

"Is this the time to play at evidence?"

"And if we're in this mess because nobody played at evidence, then what?"

O Gyeongtae's words were rough, but the procedure was necessary. He folded the mouth of the bag and looked for tape. When the station staff were slow bringing it, he pulled electrical tape out of his own toolbox.

"I don't like the color, but it beats nothing."

I checked the time written on the bag. 07:07. A minute earlier than the original ignition time, and the incident was already over. Writing the word ignition as it stood would make the record wrong. In my notebook I corrected it to pressure wave. A small revision, but one that would change the next judgment.

Jang Yura watched my fingertips.

"What did you just erase?"

"I was going to write explosion and I changed it. The passage survived, so pressure wave is correct."

"Does that difference matter?"

"It keeps the next person from mistaking Sector B for the blast point."

She nodded once. Less a sign of trust than an acknowledgment of usefulness.

The janitor said his name from the stretcher. Park Inho. His voice was cracked, and the end of it was almost inaudible. Jang Yura confirmed the name twice. I wrote it at the bottom of the notebook. The original record had said the name was unknown, but in the present there was a name. Even information recorded as unknown changes once you meet the person.

"Where was Park Inho on the list of the dead?" Jang Yura asked.

"Near the bottom. It wasn't a list I saw myself, it was an incident summary table."

"Then don't call it a list. It's a summary table."

I corrected myself.

"The incident summary table had a fatality in this section."

"Good. Say it like that and I can make a judgment."

What she was demanding wasn't a confession. It was a source. The person judging on site needed a source before she could move.

A new alert came up on the station terminal. Ventilation route change history. The early evacuation announcement at Myeongjin Station had moved up the time the platform's automatic doors opened, and the open doors had changed the underground airflow. Not the hand of a hidden enemy, but the result of the emergency bell we pressed.

I showed the screen to Jang Yura and O Gyeongtae.

"This is why Sector B was wrong. When the evacuation route changed, the air got pulled toward Sector C."

O Gyeongtae scratched his chin.

"So you rang the bell to save people, and ringing it moved the wind paths too."

"Yes."

"Next time, look at the wind before you ring."

That wasn't a rebuke, it was field instruction. I nodded. The emergency bell had moved people and it had moved the air. Both results of the same action had to be watched together.

Jang Yura put a small dot under the line about her own death in the notebook.

"Write down what changed because I lived, too."

"I don't know the scope yet."

"Then write that you don't know."

I wrote underneath it. Jang Yura survived. Scope of effect unconfirmed. Must be disclosed for the next rescue judgment.

Only after reading that sentence did she close the notebook. Even the way she folded it was different. She folded it so the time of death stayed on the outside where it could be seen, not tucked inward. A sign that it was not to be hidden.

Beneath the face of a living Jang Yura, the notebook still read 06:53, death.
