Concept: most aliens can get anxious, can get scared, can get fight-or-flight. What most aliens do not get, however, is stress. Stress is a weird thing even by human standards. It can build up over time or be something tied to a very limited situation. It can be caused by a lot of things, and it comes in a lot of different ways. But it's a core human reaction, when a situation is wrong, it causes stress until it is righted. And it even affects different people differently!
Cue Human Cassandra, on a ship with her friend and co-worker Human Pauline. The ship is crewed with a mix of species. It's a cargo ship - load up in a space port, unload in another, get news and supplies during their stops, and live as an ever-shifting family as some of the two dozen crew members, give or take, get replaced. Some leave come payday, and new ones come looking for the thrill of low-level adventure, experiencing warp drives across the safer roads of the known universe.
But getting the supplies you need, or want, in stops is never so easy. Humans are new to the galactic community, and their needs misunderstood. Most broad-edibility food is bland for them, but that's okay. A big enough bag of their condiments can last them years. But ADHD meds... now that's less easy to get, the further from Earth you are. And a contract too big for their captain to pass on came up, much farther than the two humans expected.
Cassandra's mood deteriorated, her work priorities out of order, her sleep schedule in disarray. Little by little, she grew restless, shifting moods and gears unpredictably. A few weeks in and she was a mess, barely able to keep up with the minimum her job doing maintenance and running safety diagnostics for the route charting team required of her. While Pauline could help with the mechanical aspects of keeping the ship running, picking up the "slack", the safety had to be double-checked by the charting and pilot teams. When the curves of asteroid probability reached beyond a certain level, several hundred simulations had to be run, time-consuming processes had to be used, to avoid any collision at speeds beyond speed c. Some truly exotic things happened to ships that experienced those, but none of them contained the words "surviving crew." A safe route avoided any probability of collision over .1% and when going faster than light, any choice of course required thinking in 3 dimensions plus relative time to navigate dangerous probability fields in one piece, finding time-specific corridors and accounting for a dozen variables at once.
After she had a breakdown over a path she would normally have been able to find in under a minute, Pauline spoke to a concerned pilot team member:
"You have to understand her, this is a stressful situation and she's doing her best..."
"What do you mean by 'stressful'?" Gabalt asked. The furry little creature stood on two arched legs, and barely reached up to Pauline's shoulder, opening three wide eyes with curiosity and concern in equal parts.
"Things are... getting difficult for her, and keep getting more difficult because she does not have medication to help her brain be efficient. It makes her tired, and inefficient, and as it goes on, she's less and less able to cope with the situation. The longer this goes on, the worse it gets, and that is stress. Getting more tired because it takes more energy to deal with the situation, and less efficient because she's more tired, and things get harder because she's less efficient, on and on until something can solve the problem and the stress goes away."
"That sounds... hard. Do all humans have to deal with this?"
"Well, everyone has sources of stress, but she's got a disability. Without her meds, she gets stressed all the time. Not a lot all at once, but it always adds up."
"Oh no! So she'll be stuck like that until we get closer to Earth?"
But the most momentous thing to happen this day was not her breakdown. Not an hour later, alarms blared up. The simulation holograms all displayed blinking red masses - the less-travelled "safe route" was not as well protected! An asteroid range had been detected cutting through the border field, and it was in their way!
Pauline froze up, not knowing what to do. Gabalt was too surprised to act fast. All the courses from the ship's library of regular manoeuvres suggested a crash chance of over 60%, and mere seconds to act before entering the field!
Before anyone could react, Cassandra came in running from her corner to the front of the bridge, slamming the warp drive shutdown button. Most holograms stuttered and collapsed, the exit from FTL essentially dividing one or several of their dimensions by zero.
Looking quickly at the few remaining ones and gazing at the screens showing the current outside situation like a large window would have - plus a few critical extra points of data - she adjusted the angles manually while everyone still shuddered from the gravitational and temporal whiplash of suddenly coming back into normal time. Unblinkingly, she spotted the asteroids on the route while the ship was still going, if not at relativistic speeds, still fast enough for a single pebble they met to vaporise the Whipple shields, the outer hull, the inner hull, the crew members, and the hull again coming out if they but grazed it. Confirming the angles visually, she played with the reaction wheels, the thrusters, the gravity drives, to divert the ship's course just enough to miss a collision while not risking any grave injury on board. There was no time to react - if anything showed up straight ahead on the "unaugmented" outside view screens, it was too late to not get splatted. After half the crew had had the time to get thrown to the side or on the ground due to the rough handling, she'd managed to avoid any crash.
Gabalt was reeling. While it was surely not impossible, these was the kind of moves experienced veterans would never wish to attempt, and the margins for error were ridiculously low! She'd saved the ship and everyone on it, whereas she'd been unable to do a simple safety run so soon before?
Pauline was white as a sheet, but this was nothing compared to Cassandra, shaking violently and breathing unevenly.
"Pauline? What is she doing?"
"That's... probably the adrenaline."
"It's from stress. When it comes it overcharges the body. It's like the traditional, 'fight or flight' instinct from survival in prey-predator paradigms, it lets you move fast but paralyses thought... it feels pretty bad after a lot of it is released though. Now she's crashing down, must be harrowing."
"How did she do that? And you said her thoughts were paralysed for precision manoeuvres?"
Cassandra's voice came, nearly a mutter: "I just... had to. do it."
Gabalt needed to understand what happened.
"What do you mean you had to? Someone had to do it, but why you?"
"It- it was very stressful, I saw you freeze, and so."
"But... but HOW did you do all that? That was extremely complicated, few pilots -whose main craft is directly piloting- would want to even try doing that when given a choice!?"
"I had to. do it, so I did. I couldn't. couldn't make a mistake."
"This makes absolutely no sense."
Pauline interrupted. "She just works like that. Lots of stress and when people freeze up, humans with her condition... sometimes, surprisingly, function better in the moment than others can."
"Ah. So it's a human thing. of course, it's a human thing. NOTHING MAKES ANY SENSE WITH YOUR ACCURSED SPECIES" the diminutive pilot pouted.
And so one more story of the humans doing the impossible spread around. Humans of a subtype, more easily harmed, sometimes unstable and needing help for the simplest things... accomplishing odd, unthinkable, borderline heroic feats under duress none could be expected to withstand - but only then. Cursed, blessed? No story-teller seemed too certain. But the "magical" species never stopped surprising all others. And a new proverb developed: "it's not over until the human says it is".
