One cold night, two children stand in front of a coffee shop. Snow blows all around them, and they are badly dressed for it. A boy and a girl, the barista thinks, noticing them through the plate glass. Young enough or short enough that the window-paint lettering coffee, retouched just that morning by the barista themself in blue to match the blue chalk on the sidewalk chalkboard, arcs over both their cold-huddled heads like a monochrome rainbow.

Strange clothing, the barista notes. The one they think might be a girl is in an oversized lime-green blazer, the maybe-boy in a white lab coat, like a tiny pharmacist. Both blazer and lab coat are buttoned the whole way up, but the blazer only goes so far. Beneath it, the girl’s got on what looks like a simple dark shirt that buttons up the front. No winter gear to speak of. No real coats, even. Snow in their hair. Window light pools around them: soft, buttery, looking much warmer than it is.

The barista checks the time on their lenses. Four minutes till closing. Quiet this time of evening, usually. Storm like this, the place is dead.

A normal day, they’d be finishing up wiping down the counters now. Flipping the door sign—like the chalkboard, a symptom of how terminally old-school their boss is—to closed. Walking the six blocks to the checkpoint, then the two blocks home. Tilting their head back, from time to time, to let the app on their lenses show them where the stars would be, if the sky weren’t wall-to-wall snow and smog instead.

Rag frozen in their hand, though, they’re just standing there. Watching these two weird kids devour that yellow light with their eyes.

Nine years old or so, the barista reckons. Then reconsiders. It’s the look on the children’s faces that’s lifting years off them, peeling them back to something less worldly, less certain. It’s in the way the upper half of the girl’s body is oscillating toward and away from the door, one indecisive degree at a time, while her feet, in their no doubt seasonally inappropriate attire, do not move. In the way the boy holds himself in perfect ready stillness, in a way that reminds the barista of nothing so much as their cat, facing down a spider, unsure which of them is the hunter and which the prey.

Eleven, maybe. Twelve at most. In any case too young for this shit. Unsupervised. Underdressed. Three hours into an expected all-night nor’easter. They look like they’re wearing half a Halloween costume apiece. And not the good kind. The kind you slap together out of stuff from your parents’ closets and basements when you can’t afford the ones at the party store.

The snow is coming down in big clumpy flakes now. When it hits the kids’ faces, it takes an alarmingly long time to melt.

In hindsight, the barista will wonder why it took them so long to act. Unpack, in bullet points, as part of a whole minute-by-minute replay of everything they should have done instead. Rationalize, albeit feebly.

• Because the children weren’t visibly injured.
• Because the barista has their implant set to alert them if there’s a bioweapon in the air and it hadn’t gone off in days.
• Because one of the best parts of this job is how it’s way out on the edge of the Stellaxis half of the city, just a couple of blocks from the Greenleaf one, near enough to the little strip of demilitarized zone that beyond a few small skirmishes this street hasn’t seen real combat since October.
• Because, due to the above, there was no quantifiable threat for them to need rescuing from. Just two kids, ogling a warm haven from the cold.

Because the real answer makes less sense.

Because the real answer doesn’t land as a thought, not a fully formed one anyway. It’s more of a catch in the barista’s breath every time this girl so much as shifts from foot to foot, or brushes the snow from her face, or shoves her hands deeper in her pockets, and every time the boy pointedly does none of these things. It hits as a tiny chemical shock, like getting slapped on the back of the skull. Danger, it’s telling them. Run.

The barista gives this due consideration. Then, deliberately, over the mental alarms this raises, they push it carefully away. They’re children on their own in the snow. Maybe they’re looking at the barista alone in the shop and thinking they can clean out the register and get gone before the barista can blink up a security patrol on their lenses. At their age—hell, at older—the barista would’ve done the same. Endless war fucks with you like that. Pares down your options to what starts to look a lot like one single, inevitable, ill-advised point.

The barista puts down the rag. Whatever the fuck this is, it’s not happening on their watch. They march across the warmth of the room and haul open the door. Two faces snap to them, too quickly, raising little hairs on the back of their neck. The word vampires skips unbidden across the surface of the barista’s mind. Have to be invited in.

But no. These are just a couple of cold kids who’ve clearly had a hell of a day. Close up, the blazer and pharmacist coat are snow damp but clean, a faint chemical smell wafting off them that the barista at first mistakes for the perfume of dryer sheets and then realizes they can’t quite identify. The kids themselves: also clean. Well fed. At a glance, no signs of chronic dehydration. This isn’t life for them, then. At least not yet. Just a misadventure. The kind that gets the mis- tacked on in hindsight, best the barista can tell. Plenty of those in their past. They know the signs.

In the children’s proximity, the barista’s lenses remain silent. Nothing airborne and deadly has seeped into their weird Halloween-costume attire, waiting to be unleashed on the shop’s interior. The barista blinks up a quick weapons-check interface—not exactly retail worker standard issue, but one can only hear so many on-the-job horror stories before going to a cousin of a friend of a friend with a month’s worth of tips backing a small software upgrade request—and, of course, the kids aren’t packing. Not so much as a rusty junk shop pocketknife or a few inches of sharpened rebar, and that’s maybe most surprising of all. They’re out here wandering around in what could at any minute renew its status as a conflict hot zone, and they’re defenseless.

So the barista props the door open with one hip. Tilts their head in toward that delicious drench of coffee-scented warmth. Letting the heat out, Rach—the owner, Rachel, the barista’s boss—would say. But Rach doesn’t stay for closing, and nothing fills the day-old bakery basket like a big-ass storm, and , these kids can wait for whoever they belong to just as well out of the snow as in it, and if the barista gets back to their apartment a little later than usual, honestly so what.

The kids pause to assess the barista, straddling the doorway in their jeans and undercut and apron like it’s a magic portal and they’ve got one sneaker in each world and finding both options underwhelming. The question of the kids’ footwear remains a mystery for now, as both have white plastic Comforts of Home shopping bags tied over what at least, thankfully, do look like decent boots. There is snow in their eyelashes. The barista’s pretty sure they’ve only been standing outside the window for five to six minutes, max. Could track their prints back behind them, before the snow dusts them back over. See where they’ve been. Who’s looking to follow after.

But that could be anywhere. Anyone. And they’re here now, and who knows what’s behind them. Some paths are best left unwalked, or unrepeated. It’s a big city, and not all of it as nice as Rach’s place. Not nearly.

All at once, both kids straighten as something passes between them invisibly, and despite themself, the barista shudders. Something’s off about their movement, something dreamlike, something the barista has seen before, grasps after, glances off.

It won’t be until tomorrow that they’ll realize, hands shaking hard enough to drop the stack of to-go cups they’re carrying out from storage, what exactly it is they’re looking at. By which point it will be too late to either help or hinder them. Both of which hypotheticals will strike them, suddenly, as absolutely laughable.

They’ll tell the story of this night for years to come. They live and work in a city that’s been at civil war with itself for decades and this, right here, is probably the closest they have ever come to death.

For now, whatever this weird feeling is, it only lasts that one nanosecond. Then they’re kids again and cold and hungry, and they’re tracking grimy snow onto the just cleaned tile, and the barista sighs and flips the sign to closed behind them, and then goes to fetch a mop.
