Chapter Thirteen: Commitment

The training bay dimmed.

Frost spread across the transparent partitions, clouding the glass until the other students became silhouettes. Mateo could still distinguish a shoulder turning, a hand rising toward a face. The details stopped there.

Over the next ninety seconds, the temperature dropped twelve degrees.

His ears popped.

Eight of them stood on the bay floor. The other four had drawn gallery rotation, watching feeds they could not affect.

Halvorsen’s voice carried through the partitions.

“Individual decisions. No collaboration. Your route selections will remain private until you commit.”

A current of air moved against Mateo’s face.

It strengthened.

“High altitude. Limited oxygen. The weather window is closing. Choose your route.”

The partitions disappeared into the simulation.

He stood at the foot of an icy ridge.

Blue light lived inside the ice walls. Above them, rock and snow rose in narrow spines, an ascent route threading between them before disappearing into cloud. Flags snapped along the first traverse. Each gust pressed against his jacket and found the small opening at his throat.

Catalyst brought the terrain into relation.

For Mateo, the future arrived as architecture: paths branching above paths, each possibility supporting another level of consequences. The structure grew while he examined it.

Oxygen reserves.

Weather window.

Injury probability.

Group cohesion.

Three objectives appeared beneath the data.

REACH THE SUMMIT.

ENSURE PERSONAL SURVIVAL.

MINIMIZE HARM TO THE GROUP.

No weighting. No order of importance.

Mateo noticed the omission and moved on to the routes.

The gradual ascent crossed a broad exposed slope. Fewer technical hazards, but more time on the mountain and more oxygen spent before the final approach.

The direct gully cut almost straight upward. Fast, provided nobody lost footing or fell behind. Its narrowest sections offered little room to pass a struggling climber.

The indirect flank followed a ridge between sheltering ice walls. More technical movement. Less exposure in some places, more in others. A compromise that refused to remain one once he began examining it closely.

His projections spread.

If everyone took the gully, the summit was reachable. One injured ankle could change that. So could a climber exhausting their reserves where the rope line couldn’t easily reorganize.

The gradual route reduced the chance of a fall but lengthened the exposure. The weather might close before they reached the upper ridge.

Splitting the group created another set of branches.

Mateo began assigning people to them.

Julian would favor the fastest line and trust his ability to correct. Theo would be drawn toward whatever tested the model. Aisha might choose a route that left room to respond to other people.

He stopped.

He was predicting their decisions before making his own.

The countdown continued.

Every second changed something. Oxygen diminished. Wind strengthened along an upper traverse. A route he had considered marginal became unavailable while he was still deciding whether to discard it.

He felt the loss of options almost physically, possibilities drying at their edges.

Then he chose the direct gully.

The moment he confirmed, the larger structure collapsed around the selection. Alternatives faded. Consequences remained, but they belonged to one route now.

Relief passed through him.

He disliked how little it had to do with whether he was right.

The other selections appeared as the decision phase ended.

Julian: direct gully.

Aisha. Theo. Ethan.

Ben had taken longer, but chose it too.

Leena: direct gully, moderated pace.

Then Tamar.

Indirect flank.

Alone.

Mateo looked back at the terrain.

The discarded branch returned with new importance.

There, a secondary wind front forming behind the gully. The primary forecast had folded it into a general worsening of conditions. He had done the same. The individual waves made the projection less tidy, and he had accepted the smoother version.

But wind arriving in a surge was different from wind increasing gradually.

One climber slowed in the gully, the others compressed behind them, and the front arrived before the line could recover.

He ran the sequence again.

Had Tamar seen that?

Her marker moved toward the flank. He tried to open the route selection and found it locked.

He had wanted the others’ choices to confirm his own. Most of them had.

Now the one disagreement occupied more of his attention than all the agreement.

The simulation accelerated.

Wind moved through the gully with a long, hollow sound.

The seven climbers advanced on a shared rope, their bodies reduced by heavy clothing to bright shapes against the ice. Mateo felt each hesitation through the line: a brief tightening at his harness, a pause, slack returning.

The exercise distributed everyone’s vitals across the group.

Leena’s oxygen reserve. Ben’s skin-temperature warnings. Julian’s exertion. Tamar’s separate position on the flank.

Mateo tried to reduce the display.

The critical readings remained.

He understood that this, too, was part of the exercise. Whatever happened to another climber would happen in view of the numbers.

For a time, the gully worked.

Ethan broke trail where the powder deepened, spending strength that made each following step easier. Julian found the line through blue ice and raised a fist when a surface looked unreliable.

The signal traveled backward.

Slow.

Hold.

Move.

Nobody spoke unless they needed to. Breath had become something to conserve.

The world narrowed to the next placement of a boot, the scrape of metal against ice, the movement of the rope ahead.

Then Julian slipped.

Powder concealed a plate of smooth blue ice. His foot slid sideways, his weight dropped, and the rope jerked.

Ben braced. Ethan planted himself. Aisha absorbed the pull without letting it carry her off balance.

The line held.

Julian recovered his footing.

For several breaths, nobody moved.

Then he started again, faster.

Mateo understood the adjustment. They had lost time. The forecast had not paused with them.

No one objected.

Leena’s reserve began dropping more quickly.

She shortened her stride to keep the rhythm. Her breathing, audible when the wind eased, no longer matched the pace of the line.

Mateo watched the numbers.

A branch he had treated as unlikely began asserting itself.

He could call for a slower pace. That would extend their exposure and sacrifice more of the weather window. It would also mean telling six people who were still moving that the current solution was failing.

He considered how to phrase it.

The front arrived before he spoke.

Seventeen minutes early.

First came the sound, deep enough that he felt it through his chest. Then ice struck his cheeks and gathered along the rim of his goggles.

Julian shouted something.

The wind took it.

The line ahead disappeared. Mateo could barely make out Aisha’s yellow jacket, its color dulled to gray by the snow between them.

Updates filled his feed.

Theo’s responses were slowing under the simulated hypoxia. Ben’s cold-injury warning changed level. Leena’s oxygen saturation crossed a threshold.

The exercise presented its conclusion.

SUMMIT, FULL TEAM: NOT VIABLE

SUMMIT, PARTIAL TEAM: VIABLE

FIXED ANCHOR: 40 METERS

SHELTER RATING: SURVIVABLE

Mateo looked for another branch.

There were several.

Turn back. Continue together more slowly. Stop at the anchor. Leave someone sheltered and press on.

Each required surrendering something the exercise had told them to want.

The rope moved.

They reached the anchor by following Julian’s signal through the whiteout. A recess in the ice gave partial shelter, enough for Mateo to see Aisha turn toward Leena.

Aisha’s hand closed around Leena’s harness.

Then she reached for the carabiner.

Mateo knew what she was doing.

He ran the numbers while she did it.

Four seconds.

Leena’s line transferred to the fixed anchor. The connection to the climbing chain released.

Leena closed one gloved hand around Aisha’s wrist.

A brief hold.

Then she let go.

Mateo couldn’t read her face through the goggles.

Aisha checked the new attachment. The rope drew tight again, reorganized around the place Leena had occupied.

The others began climbing.

Mateo went with them.

Behind him, one figure remained in the recess. Snow passed between them until the bright jacket was only a muted patch against the ice.

Then it was gone.

The calculations supported what Aisha had done. Leena had shelter. The remaining climbers could reach the summit within the reduced window.

Mateo kept returning to those facts.

They offered an ease he didn’t quite trust.

He had not proposed the choice. He had not touched the carabiner. In the time it took him to confirm that the action was defensible, someone else had completed it.

But he had seen the reserves dropping before the storm.

He had also kept climbing.

Ninety-two simulated minutes later, they reached the summit.

There was no view.

Cloud pressed against the ridge. A marker stood half buried in windblown snow.

OBJECTIVE ONE: ACHIEVED

Mateo stopped beside it.

The shared display still carried Leena’s position far below.

Her saturation had recovered within minutes of resting. Now, while the summit group struggled to catch its breath, her vitals were the healthiest on the line.

He looked from her numbers to the objective confirmation.

Both were correct.

Neither explained what they had accomplished.

The mountain disappeared.

Warmth returned gradually. Mateo’s body remained braced against wind that no longer existed.

The partitions retracted, revealing the other students at their stations. The gallery screens still held fragments of the ascent.

Leena stood several meters away.

Tamar was looking at Halvorsen.

“How do you think you did?” Halvorsen asked.

Mateo pulled at his collar. His throat felt dry.

Nobody answered.

Halvorsen waited.

Then she turned to Tamar.

“You didn’t summit.”

Tamar’s eyes moved to the gallery screen. The completion marker still glowed above the place where the six of them had stood.

“No.”

“You avoided the secondary front. You completed your route and returned without injury.”

Tamar nodded.

“Walk us through the choice.”

She rubbed her thumb along the edge of her sleeve.

“The gully was fastest. I thought most people would take it.”

“Why didn’t you?” Ethan asked.

Tamar looked around the group. Her thumb stopped moving.

“I kept thinking about Kara.”

Ethan’s expression changed.

“I could have stopped chasing her. There were about ten chances.” She looked toward the floor between her feet. “By the end, all I wanted was to land one hit.”

Mateo remembered the sound. The brief, sickening interval before anyone moved.

Tamar drew the edge of her sleeve over her thumb.

“When I looked at the gully, I kept working out how to get through it faster. Every problem was something I could make up for higher up.”

She glanced at the map.

“I thought I might do it again.”

“Lose control?” Ethan asked.

“Keep going.” Her answer came quickly. Then, more quietly: “Until something happened.”

For a moment, the only sound was air moving through the vents. Mateo could still feel the imaginary wind against the damp skin beneath his collar.

“The front was there,” Tamar continued. “Behind the main forecast. If someone slowed down, everyone behind them would have to slow down too.”

“The flank had technical hazards,” Theo said.

“I could stop there. There were places to turn around without making six people stop with me.”

She looked at Ethan.

“I thought we’d find reasons to keep climbing. I knew I would if I went with you.”

Mateo looked down.

He had found several.

Theo studied the terrain map.

“You included what we’d do.”

Tamar gave a small shrug.

“I included what I’d just done.”

Halvorsen brought the flank into focus. Tamar’s route traced a thin line between the ice walls. Near its highest point, a connecting traverse curved toward the summit approach.

“You paused here.”

Tamar looked up.

“I checked the crossing.”

“And?”

“The front would reach it before I got across.”

“Then you checked it again.”

A little color rose in Tamar’s face.

“I still wanted to go.”

Mateo watched her eyes follow the connecting route. Even with the mountain gone, she seemed reluctant to leave that narrow line alone.

“So what changed?” Halvorsen asked.

“Nothing.” Tamar pulled her sleeve straight. “That was why I turned around.”

Aisha had been looking at the floor.

“She saw where we’d end up,” she said. “A point where the oxygen numbers would make the choice look settled.”

She raised her eyes toward Leena, then away.

“I told myself we didn’t have an option.”

The room remained quiet.

Ben let out a thin breath.

“So the official finding is that I’m a strong personality.”

Mateo turned toward him.

“What?”

“That’s what I’m taking from this. We’re stubborn, highly driven people. Apparently I qualify.”

A small, uncertain laugh moved through the group.

“I’d like that in writing,” Ben added. “Most of my feedback so far has involved falling.”

“Ben,” Aisha said.

He looked at her.

“Give us a minute.”

His expression changed.

“Yeah. Sorry.”

He folded his hands.

Ethan hadn’t laughed.

“You thought we’d stay on the route,” he said to Tamar. “Even when it got worse.”

“I thought we might.”

“And you went somewhere else.”

“Yes.”

She held his gaze, though her fingers had found the edge of her sleeve again.

“We weren’t allowed to talk before choosing. I had to pick something.”

Mateo remembered her route appearing after he committed. He had recognized the possibility of the front then.

There had still been time to say something during the climb.

Julian spoke from beside the central partition.

“The objectives weren’t ranked.”

Halvorsen looked at him.

“Summit. Survive. Minimize harm.” He counted them on his fingers. “Was there a route that got all three?”

“What did your run show you?”

“That getting to the summit meant accepting more harm than stopping would have.”

“And which objective did the group treat as fixed?”

Julian glanced toward the final confirmation on the gallery screen.

“Summit.”

Halvorsen waited.

“We could change the team,” he said. “The pace. Who went on. We didn’t question that.”

He didn’t look satisfied with having found the answer.

After a moment, he turned toward Leena.

“When I slipped, I pushed to make the time back. Your reserves started dropping faster after that.”

Leena met his eyes.

“The system flagged the threshold,” he continued. “But I helped get you there.”

“I know,” she said. “I was trying to keep up with you.”

Julian nodded once.

There was nothing easy for him to say after that.

Leena turned toward Tamar.

Her hands were folded. The fingertips had gone pale where she pressed them together.

“You knew it would be me.”

Tamar didn’t answer immediately.

“My reserves,” Leena said. “You could see them before we started. You planned around the part where I couldn’t continue.”

“I thought someone might…”

“But you thought it would be me.”

Tamar held her gaze.

“Yes.”

The answer seemed to take effort.

Mateo remembered Leena sitting beside her at dinner, waiting while Tamar tried to explain what had happened on the mat. She had stayed through the silences. Asked another question when the rest of them had run out.

Now Tamar looked down at her hands.

“Your reserves were lower. I thought…”

She stopped.

Leena waited.

“I thought that was a reason to choose another route.”

“You did,” Leena said.

Tamar’s mouth opened slightly.

Then she let her sleeve go.

Mateo could see how she had reached her decision. He could follow every step of it. Across the room, Leena stood with the pale marks of her own fingertips fading from the backs of her hands.

Then she said, “Aisha.”

“Yes.”

“You didn’t hesitate.”

“No.”

Mateo remembered the four seconds. The carabiner moving through Aisha’s gloves. Leena’s hand around her wrist.

“Would you do it again?”

“Yes.”

Aisha’s voice remained level.

“Faster, if we were in that position again. Those four seconds cost the line eleven.”

Leena turned fully toward her.

Whatever she had expected, it had not been an answer expressed in seconds.

“Okay,” she said.

Aisha drew a breath, but Leena had already looked away.

Mateo felt the distinction between the answer Aisha had given and the question Leena might have been asking. He could model both. He could see reasons for each.

That did not give him a useful thing to say.

Halvorsen looked around the group.

“You chose routes individually. Then you inherited the consequences together.”

She let her attention rest on the summit marker still visible above them.

“A strategy can attract agreement because it serves the objective everyone assumes matters most. Catalyst can make the route clearer. It cannot choose what you owe one another.”

She ended the replay.

The mountain vanished from the last screen.

“Take time before the next session.”

Then she left.

Mateo remained beside his station as the others began to move.

He remembered the relief when he committed to the gully: all those branches falling away, one path left to follow. He had taken the quiet afterward as a sign that he had done the difficult part.

Across the room, Leena was gathering her things. Aisha stood a short distance from her, waiting for an opening that did not come.

Tamar lingered beside her station. When Leena passed, she looked up, but Leena was already turning toward the doors.

Mateo tried to name what he had felt when the alternatives disappeared.

It had been relief.

He was no longer willing to call it clarity.
