The Cost of Surviving

The numbers went up on the whiteboard first. Nineteen rescued, three critical, six waiting for transport. The last line read: mechanic, right hand amputated, awaiting surgery.

I read those numbers three times. The nineteen were survivors who had not existed before. My finger stopped above that line, then came down. The mechanic's glove sat on a chair under the board. The glove had been cut away at the wrist. The blood had dried and hardened to black.

Jang Yura told me to look at the patient, not the glove.

"If they're alive, there's a next treatment."

"I know that."

"Then stay on your feet. Your hands can move while you calculate."

I reached for the lid of the first aid kit. She handed me a name tag instead of bandages. She meant for me to write names onto the rescue roster. I felt caught in the habit of counting people as numbers first. The feeling was useless. The names were necessary.

O Gyeongtae was coughing in the corner, bagging filter fragments. He folded the mouth of the bag over twice.

"Don't throw out the orange powder. Somebody's going to call it old dust again later."

"What about faulty maintenance?" I asked.

"If it's faulty maintenance, that's my name they curse. But this isn't dust from our station. It's got a different grit to it in your hand."

He spoke in the language of the field, but his hands were preserving evidence. Jang Yura added a new line to the board. Orange particulate collected. Lower Section C. She still had not given my notebook back.

Outside the station was nothing but sirens. One ambulance stopped while reversing, and another vehicle blocked it in from behind. In the original timeline, Jang Yura's vehicle had let the Haneul Hospital oxygen transport truck pass before coming into Myeongjin Station. Now that vehicle was pressed up against the platform entrance to load additional survivors.

I looked at the dispatch screen. The route for the Haneul Hospital oxygen delivery truck was flagged in red for detour. Reason for detour: emergency vehicles holding on the Myeongjin Station approach road. The alarm I had pulled and the people Jang Yura had saved were rewriting the roads.

Jang Yura looked at the screen beside me.

"Is that a problem?"

"That vehicle wasn't supposed to come through here. It went straight to Haneul Hospital."

"Drop the 'supposed to' part."

I zoomed in on the dispatch table. Position of the oxygen delivery truck, estimated arrival, detour distance. I checked whether these were numbers that changed behavior.

"At this rate the hospital arrival is at least thirty minutes late."

"Thirty minutes puts who at risk."

"The neonatal intensive care unit and the reserve oxygen for the operating rooms."

Jang Yura's face went hard. She did not blame me. She picked the thing that was faster than blame.

"Then we have to disperse the Myeongjin patients. If we hold them here, the delivery truck can't get through."

"We can't reduce the number of rescues."

"I didn't say reduce. I said change the transport order."

She opened the doors of three ambulances herself. She separated the patients who could walk, the ones who needed oxygen, and the ones whose bleeding was already controlled. I lined up the original death count against the number we could currently transport. Fixing the roster was not a matter of erasing letters. It was a matter of changing vehicles, oxygen tanks, and the width of a single doorway.

One of the paramedics shouted.

"Chief Jang, the hospital's asking about the oxygen truck detour."

Jang Yura held her phone out to me.

"You talk. If you're the numbers guy, do it with numbers."

I took the call. The voice of the hospital staffer kept cutting out.

"The oxygen truck is turning back because of the Myeongjin Station accident. Our emergency oxygen reserve is still sufficient for now, but it drops if a second surgery opens."

"Give me the reserve in minutes, please."

"Who is this?"

"Han Igyeom, Haeul City Disaster Modeling Office. I'm not the one in charge, but right now I need the number."

After a short silence I heard a keyboard.

"By current calculation, 71 minutes. That's before factoring in the delivery delay."

"And with the delay."

"Still calculating."

The call did not end there. Behind him another voice called out oxygen line pressure. Jang Yura kept issuing patient dispersal orders, and O Gyeongtae asked a station attendant about the usable width of the tunnel. Nobody was waiting on my memory of the future. That was why things moved forward a little at a time.

I went back down to the maintenance control room. O Gyeongtae had the Argos maintenance command log open. On the screen was the central command scheduling queue. Originally I had read this log in an investigation report 27 days later. Back then the Myeongjin Station accident had been classified as a minor precursor.

Now the log held a command from before the accident.

Lachesis maintenance scheduled. Priority circulation, lower Section C ventilation. Execution tag 06:49. Creation tag 06:53.

I closed my eyes once and opened them. The creation time came after the execution time. In a normal log that was impossible. The 06:53 that was the accident time in my memory now sat there as a creation tag, and the actual execution had moved four minutes earlier.

O Gyeongtae tapped the screen with a finger.

"So did the machine get drunk, or did a person mess with it?"

"It may be neither."

"Then what is it."

"I don't know yet."

The words felt strange in my mouth. But pretending to know what you don't know is how you pull the wrong lever next. I wrote B in my notebook. Official log. Not witnessed directly, but a record produced by equipment in the present. The reliability had gone up, and the cause was blank.

Jang Yura stood in the control room doorway. She was holding my notebook.

"What's Argos."

"The city synchronization network. It aligns power, traffic, evacuation broadcasts, and hospital emergency power priority."

"And it just touched a ventilation duct."

"According to the log, yes."

"'According to the log.' Convenient. There's no one accountable in it."

I could not argue. The log was a word that deferred accountability. But right now the next choice came before accountability. Jang Yura pointed at the bottom of the screen.

"If the creation tag is after the accident, then where did this command come from."

"To confirm that I need an authorization code."

"You don't have one?"

"Not right now."

"Then start with who's in danger right now."

She got the hospital back on the line. This time the staffer spoke first.

"Calculation's done. Factoring in the delivery delay and operating room usage, emergency oxygen reserve is 43 minutes."

The fan sound inside the control room dropped lower. I looked at the 06:49 on the screen and the 43 minutes in the phone at the same time. Saving nineteen more people had not been undone. The mechanic's hand was not coming back either. The oxygen truck was still blocked.

Jang Yura did not ask. She ordered.

"Stop counting how many you saved and tell me who's in danger now."

"Haneul Hospital."

"The route."

I opened the dispatch screen again. The north exit of Myeongjin Station was blocked. The south road was taken up by ambulances. The east connecting passage was still open. In the original timeline it had been a route no one ever needed.

"If we go out through the east passage, we can turn two of the emergency vehicles blocking the delivery truck. The cost is that securing the maintenance control room log gets delayed."

Jang Yura still did not hand back my notebook.

"So it's evidence or people again."

"This time it's oxygen."

"Then oxygen first."

O Gyeongtae tucked the filter bag into his chest pocket.

"I'm coming too. Looking at the state of this station, no way the hospital's machines are in any better shape."

"You need to stay here and guard the log," I said.

"The log you can copy. The route I know. Young man like you goes hunting for a door with your eyes on a screen and gets there late."

He made a correct point in an uncomfortable way. I said nothing more. Jang Yura finished the patient dispersal and shut the last ambulance door. The road opened a little. The oxygen delivery truck's position started moving on the screen again. But the hospital timer had already gone down.

We ran for the east connecting passage. The receipt notebook folded over inside my pocket. Nineteen survivors. Mechanic's right hand lost. Ignition point in Section C, X. Argos command creation tag 06:53, execution 06:49. Haneul Hospital oxygen 43 minutes.

Jang Yura did not hand the notebook back even while running.

"I'll carry it."

"On what grounds."

"When you hide the numbers, people move late."

At the far end of the east passage, the emergency alert for the hospital district went off. The speaker had a lower tone than the one for the station accident.

The mouth of the east passage was narrower than I expected. For a single ambulance to get through, the station attendants had to fold back a temporary fence. The fence's locking pin was bent. O Gyeongtae bent at the waist to pull the pin out and started coughing.

Jang Yura caught his hand at once.

"That's three coughs. Get back."

"It was two."

"I counted. Three."

O Gyeongtae stepped back with a disgruntled look. Instead he threw the tool to a station attendant.

"Not the red handle, the black one. Red is the one that locks it."

The attendant did exactly that. The fence folded and the first ambulance got through. The knowledge moved even without O Gyeongtae's own hands on it. A living variable was not someone who only used his own hands. It was someone who changed what other people's hands did.

I checked the oxygen truck's route on the dispatch screen again. The detour distance had shrunk, but the estimated hospital arrival was still late. Open one road and a bottleneck formed somewhere else. The ambulances funneled in by the Myeongjin Station accident were taking up the turning space in front of the hospital too.

Jang Yura raised her radio.

"Clear the turning space in front of the Haneul Hospital emergency wing. The three critical patients go to the temporary tent on the south side. Get the oxygen delivery truck in first."

Someone protested from the other end of the radio.

"Emergency patients have to go in first."

"If the oxygen doesn't get in, the beds that take those emergency patients stop. Any family who can walk, get them out and move them on foot."

She was not pushing patients aside. She was only stating the order: the facility called a hospital has to be kept alive before patients can go into it. I wrote that distinction down. Nineteen rescued was a victory, and the victory was what blocked the hospital entrance. The cause was not fate. It was the width and the order of vehicles.

The station operations commander stood beside me. He did not grab my arm anymore. He pointed at the log on the screen instead.

"This 06:53 creation tag. It's the same as the accident time you gave us earlier."

"Yes."

"So did you create this command?"

"No."

"Can you prove that?"

The server evidence had vanished back at the very start. I could not prove it. So I said only what was possible now.

"What I can do is disclose the gap between the current log and my memory. I don't know who created it."

He was not satisfied. A dissatisfied face had to be recorded too. When information is short, people suspect. Suspicion gets in the way sometimes, but it was safer than believing me without question.

O Gyeongtae spoke while watching the log screen from the side.

"Creation time later than execution means the ledger was written backwards. Trust a backwards ledger and run the machine, and fingers go flying."

The mechanic's severed glove came into my sight again. I opened my hand inside my pocket. I tried not to look at the glove for long, but if I never looked at it, the cost would stay a number and nothing else. The mechanic is alive. The hand is not coming back. I needed both sentences at once.

A second call came from the hospital staffer. This time there was breath mixed into his voice.

"The delivery truck reached the access road but it can't get in because of the emergency vehicle queue. Recalculating the oxygen reserve."

"How much has it dropped."

"Still showing 48 minutes."

Someone beside him shouted. One more operating room had opened, he said. The staffer typed again. I felt like I could hear the number going down.

"Correction. 43 minutes."

Jang Yura did not take the phone from me. Instead she put out a hand and had me switch on the speaker. The station attendants and paramedics nearby all heard the same number. A hidden number becomes an order later; a disclosed number became action now.

I wrote 43 minutes in the notebook and split the causes into three lines beside it. Early evacuation at Myeongjin Station, ambulance detour, blocked hospital turning space. Below those I noted the Argos command executing four minutes early, kept separate. Even the same number could be a movement cost in one place and a system log in another. Mix them and the next judgment goes cloudy.

Jang Yura looked at the page.

"This time you wrote who's in danger first."

"Because you asked."

"Next time write it before I ask."

That was closer to a condition than a rebuke. I wrote must be disclosed at the top of the page. Jang Yura checked it and nodded.

I did not press the button to end the call. I let everyone hear the same alert all the way through. When the numbers cut out, people remembered whichever version suited them.

Jang Yura would not let me lower the hand holding the speaker. Even the sound of the hospital staffer calling out valve positions in the background stayed with the scene.

"Haneul Hospital emergency oxygen reserve: 43 minutes."
