Chapter 16 - Gravity

"Intelligence is the ability to adapt to change."

—Stephen Hawking

The hangar was brand spanking new, a large space where the metal walls and deck plating gleamed under the bright overhead lights. The air was almost too clean, the kind that made him want to breathe shallowly, with a faintly citrusy tang from the final system flushes.

But here was Captain Luca, on his hands and knees, in a dimly lit corner, waging war against a stubborn, greasy stain that had the audacity to mar his damn floor. It was a dark, ugly blotch, mocking the otherwise flawless surface.

He attacked the stain with a scrub brush, sweat dripping into his eyes, the tight fabric of his bodysuit clamped against his skin. The bristles scraped against the metal, a harsh sound that blended with the steady hum of the ship's machinery. Nobody had mentioned this part of the job.

He knew enough to recognize engine grease when he saw it. He'd never thought to check if the System store had anything for stain removal. Seemed like an oversight, in retrospect.

“Fucking grease monkey,” he muttered, picturing Ryan's smug face and his usual trail of questionable substances. "You'd think one of these idiots would have the decency to clean up their own damn messes."

He paused, leaning back on his heels, to examine his handiwork. The stain had faded, but it was still there, a faint shadow against the gleaming metal. "Son of a bitch," he hissed, grabbing a fresh rag. This stain was a personal affront, a violation of the sanctity of his ship.

The bristles of the brush caught on a rough edge, jerking his hand. He swore under his breath, rubbing his knuckles before diving back in. His head was starting to hurt, the cleaning fluid working its way in behind his eyes.

Then the alarm blared.

---

It was loud, way too loud, the sort of noise that bypassed his ears and went straight into his teeth.

Luca dropped the scrub brush and ran. His brain hadn’t caught up yet, but his legs were already moving, pounding across the hangar deck toward the exit while red emergency lights strobed over the Percival’s hull. Every alarm on Europa had started like this, and the people who stood still trying to figure out what the alarm meant were the ones who didn’t make it out.

“Bridge, report! What’s our status?” he called into his comm unit.

Emily came back fast. “Captain, we have multiple system alerts. Cascade warnings from the FTL drive calibration sequence.”

His stomach dropped. They were almost at the Oort Cloud passage, and the preliminary FTL calibrations were the part where you didn’t get second chances.

“Ryan, Danny! What the hell is going on?” He was sprinting now, boots hammering on deck plating, heading for the nearest lift.

Ryan’s voice came through breathless. “Luca! We’re running the final power conduit stress tests for the Reality Anchor Field! There was a surge. Danny’s trying to isolate it, but the whole damn board lit up like a Christmas tree!”

Great, wonderful. “Is the FTL drive active?”

“Not yet! But something’s drawing power erratically!” Danny yelled, his voice cracking on the last word.

Luca stepped into the lift and the floor disappeared.

One second he was standing. The next he was floating, stomach in his throat, arms pinwheeling at nothing. The gravity had cut out completely, and then it slammed back and he hit the lift floor knee-first. Pain shot up his leg and his teeth clacked together hard enough to taste metal.

“Fuck,” he hissed, grabbing the railing to pull himself up. His knee was already throbbing. “Bridge! Report!”

“Intermittent gravity failure, ship-wide!” Zoe sounded like she was talking through her teeth. “It’s cycling! Hold on to something!”

The lift started moving, jerky and wrong, like a carnival ride that had been assembled by people who hated children. He braced himself against both walls. Power surge during FTL calibration and the gravity was cutting in and out. Every single part of that sentence was bad.

The corridor to the bridge was worse. Each step was a gamble on whether the floor would stay where it was. His body kept tensing for the next drop, and he couldn’t stop it.

He hit the bridge doors at a dead run.

Emily was already strapped into her XO station, harness tight across her chest, hands moving across her console while she rerouted power. Her ponytail had come half undone and loose blonde strands stuck to the side of her neck. She didn’t look up. She didn’t need to. She was already doing the thing he was about to ask her to do, because that was what Emily did, and even in the middle of this he noticed. He always noticed.

Zoe had both hands on navigation, compensating for the gravitational mess. Danny was hunched over his science station, sweat running down his temples, coordinating with Engineering below. He looked about two seconds from throwing up.

“Talk to me,” Luca said, dropping into the command chair.

“Massive power surge from the FTL calibration sequence in Engineering,” Emily said. Still not looking up. Her fingers didn’t stop. “Cascaded into the gravity emitter network. FTL capacitors are approaching overload. Ryan and Chris are trying to manually discharge them and isolate the surge at the source.”

Luca looked at the FTL status display, deep red and pulsing. That was not a color he wanted to see on anything related to the drive that was supposed to punch them through space.

“How bad?” he asked.

Danny answered without turning around. “If Chris and Ryan can’t start the discharge sequence in the next two minutes, we get a containment breach. Best case, the FTL drive is dead. Worst case...” He let the sentence hang there.

Luca got the picture, yeah.

“Engineering, I need options. Right now.” His voice came out rougher than he meant it to.

Danny spoke first. “I can do a full system shutdown. Slow, controlled bleed of the capacitors. It’s safe, and it guarantees we don’t blow up.” He paused. “But it’ll cause thermal stress on the secondary conduits. Three to four days of diagnostics and repairs before we can try another calibration.”

Four days sitting dead in the water while whoever was trailing them closed the gap made Luca’s jaw tighten.

Ryan cut in before he could respond. “Forget that. The primary relays are fused. I can bypass them, go straight to the manual discharge valve, and force it instantly. But if I get the energy feedback loop wrong...” A beat of silence. “It flash-fries the entire capacitor bank. Drive’s gone. Permanently.”

Those were his options: go slow and safe and lose four days they couldn’t afford, or go fast and risky and maybe lose the FTL drive forever. He could feel Emily watching him, not pushing or suggesting, just waiting and trusting him to make the call.

That trust was heavier than the decision itself.

He could guess and pick one and hope.

Or he could burn [Crisis Routing] and actually know.

The ability sat in the back of his skull like a fire extinguisher behind glass. Twenty seconds of clarity. Twelve-minute cooldown. Not as bad as [Systems Analysis Burst], but if the crisis cascaded again before Engineering stabilized the drive, he’d be making the next call blind.

The bridge shuddered. Another gravity hiccup. Danny’s capacitor graph ticked higher.

Fine. Better stupid later than dead now.

He let the ability go.

[Crisis Routing]

The System imparts emergency-triage knowledge: what to vent, what to isolate, what to reroute, what to sacrifice, and what must remain protected to preserve ship survival.

For 20 seconds, the most effective crisis-response chain resolves into a single actionable sequence.

Base Duration: 20s

Adjusted Duration: 27s

Base Cooldown: 12m

Adjusted Cooldown: 9m 55s

The pressure hit like a spike behind his eyes. The bridge display cracked open into a triage tree and everything rearranged around what to vent, isolate, reroute, and protect. Danny’s shutdown path lit clean blue: safe, controllable, too slow. Ryan’s bypass burned red-white through the fused relays, ugly but viable if Chris got the manual discharge valve open before the feedback rebounded into the anchor field. Three seconds late and the capacitor bank was toast. If he got it done on time, the surge bled out and the drive lived.

“We don’t have four days.” The words came out hard and flat through the pain. “Ryan, do the bypass. Chris, get on that valve and stay ahead of the feedback loop. Now.”

“Got it, Captain!”

Chris came on the line, breathing hard. “He’s on it, Captain. It’s gonna be close!”

Luca watched the FTL readings on Danny’s display climb deeper into red. His hands were locked on the armrests of the command chair and he could feel every seam in the material digging into his palms. The numbers kept ticking up, and somewhere in there he stopped breathing.

Come on. Come on.

A series of heavy thunks rattled through the ship’s frame from somewhere below, followed by a high-pitched whine that dropped fast and died. The red on the FTL display flickered, held for one ugly second, and then started falling, slow at first, then faster, sliding from red to amber to green.

The bridge went quiet, not calm so much as empty, with everyone exhaling at the same time.

“Capacitors discharging,” Ryan said over the comms. His voice was shaking. “Field surge contained. We got it, Captain. FTL system is stabilizing.”

Luca let his head drop back against the chair. His hands were trembling and he couldn’t make them stop. “Good work. Stand by for full diagnostics.”

He felt Emily look at him. When he turned his head, she was already back at her console, but there was a softness around her eyes that said she’d been watching him through the whole thing. She gave him the smallest nod, not really a congratulations so much as You’re okay. We’re okay.

He didn’t trust himself to nod back, so he looked away.

The bridge doors hissed open and Joey stumbled in looking like he’d been in a fight with a storage closet. His hair stuck out in four directions, his face had a greenish tint from the gravity fluctuations, and he was clutching a datapad in one hand and a half-eaten protein bar in the other. Standard Joey.

“What in the hell was that?” Joey demanded, looking from one face to the next. “I was trying to organize the medical supplies! Did someone break something again?”

Luca almost laughed. “Almost” being the key word, because about three seconds later Ryan and Chris came through the lift doors and whatever humor he had left evaporated.

They were both flushed and soaked through their bodysuits, streaked with what looked like coolant. Ryan’s jaw was set and his whole body was wound tight, and Luca knew that look. He’d known Ryan since they were twelve. That wasn’t leftover adrenaline. That was fury looking for a target.

“What the fuck, Danny?” Ryan went straight at him. Danny was still hunched over his readings, pale and drained, and Ryan got right in his space. “You said that diagnostic sequence was isolated! You said it wouldn’t feed back into the primary capacitor array!”

Chris was right behind him, jaw locked. “We nearly blew the damn drive, Danny. The entire ship. Because you skipped the isolation protocols.”

“We’ve been pulling eighteen-hour shifts trying to prep this drive!” Ryan was pacing now, hands in his hair, then pointing back at Danny. “You think we’ve got time to babysit every stress test you run? This wasn’t some harmless glitch. People could’ve died.”

Danny flinched. He pulled in on himself, shoulders curling, and Luca watched it happen with a sick feeling in his chest. Danny was the kid who’d apologize for breathing too loud. Always had been. And the worst part was that Ryan wasn’t wrong. Danny had screwed up. The interlocks were there for a reason and he’d gone around them.

But Ryan being right didn’t mean Ryan got to do this.

“I... I thought I had,” Danny said so quietly Luca almost missed it. “The schematics showed a fail-safe. I ran the simulation...”

“Simulations don’t mean shit when you’re manually overriding safety interlocks on a system that can tear reality a new one!” Ryan was in his face now, close enough that Danny had to lean back. “This isn’t some college lab experiment!”

Luca moved. He put himself between them and shoved Ryan back a step, palm flat on his chest. “Hey. Back off.”

Ryan’s eyes snapped to him, wild. “He nearly got us all killed, Luca!”

“I know what he nearly did.” Luca kept his hand up. His voice was steady, which was impressive considering his heart was trying to exit through his ribs. “Screaming at him isn’t going to un-fuse the relays.”

“That wasn’t a minor error,” Chris said from behind Ryan. “That was negligence.”

And there it was. The word hung in the air and Luca could see it land on Danny like a physical blow. He looked at Ryan, his best friend since forever, vibrating with anger he’d earned. He looked at Chris, who’d been elbow-deep in the drive with Ryan when the surge hit, who had every right to be furious. And he looked at Danny, who had already gone somewhere deep inside himself where he was going to stay for days.

Luca needed to say something captain-shaped, something that acknowledged Ryan and Chris were right without letting Danny shatter. He had no idea what that was.

Danny saved him the trouble. His jaw tightened and he met Ryan’s eyes. “I know.”

Luca could hear what it cost Danny to hold himself steady.

Then Zoe stepped in. She slid off her console and planted herself between Ryan and Danny like she’d been waiting for her cue. She was six inches shorter than Ryan and it did not matter even a little bit.

“That’s enough,” she said. She didn’t raise her voice, and somehow that was louder than Ryan’s shouting. “Both of you. He made a mistake. A big one. But you screaming in his face isn’t teaching him anything he doesn’t already know.”

Ryan opened his mouth and Zoe talked right over him.

“He knows he fucked up, Ryan. Look at him.” She didn’t break eye contact. “You think he’s not already ripping himself apart? What he needs is to understand how the fail-safes got bypassed and why his simulations didn’t catch the surge. Not... this.”

Luca stood there and let Zoe do the thing he should have done. She was better at it and always had been. He was good at making the call under pressure. The people part afterward, the part where everyone was scared and angry and needed someone to hold it together, was where Zoe ran the show.

She turned to Danny, her shoulder brushing his arm. “Danny. What happened with the interlocks?”

The shift cut through whatever Danny had locked down. He swallowed hard, looked at the floor, then back up at Zoe.

“I thought the simulation accounted for the cascading effect from the secondary conduit when I stressed it to theoretical maximums,” he said. His voice was raw. “The interlocks, I had to manually disengage them for that specific test parameter. I was trying to find the absolute breaking point of the pre-charge cycle. Give us a better margin for error on the actual jump.” He stopped. Swallowed again. “I didn’t think the feedback would jump the primary relays that fast. It was instantaneous. I miscalculated. That’s on me.”

Zoe turned back to Ryan and Chris. “There’s your explanation, not an excuse. Now we can pull the logs, find where the simulation parameters went wrong, and make sure it doesn’t happen again.” She held Ryan’s stare for another second. “Unless you’d rather keep yelling. Your call.”

Ryan ran a hand through his hair, which was already a disaster. He didn’t say anything, but he stepped back. Chris looked away first, some of the rigidity going out of his shoulders.

Joey, who’d been frozen by the door this entire time, cleared his throat. “So... anyone want some meatloaf? Or maybe a sedative?”

Nobody laughed, but the silence after it was lighter. Joey’s timing was terrible and perfect at the same time, which was just Joey.

Zoe moved closer to Danny. “You’re good. Go get some water or something before you pass out on me.” She squeezed his arm once and let go.

Danny managed a thin smile. Some of the color came back to his freckled cheeks. Not much, but enough.

“Yeah,” Luca said. He let out a breath that felt like it had been stuck in his lungs for twenty minutes. “Let’s try to keep the near-death experiences to one per day, alright? I can’t keep doing this.”

His legs were shaky. He wasn’t sure anyone else could tell, but he could feel every muscle in his thighs buzzing with leftover adrenaline that had nowhere to go.

“I need a drink,” he said, and walked off the bridge before anyone could answer him.

The corridor was quiet. The ozone smell from the surge still hung in the recycled air, sharp and chemical. His hands were still trembling. He shoved them in his pockets and kept walking.
