Flicker

Flicker had not always trusted the half-step.

When they were small, they used to hate how their body did things without asking. A loud clap and they'd jump. A hot pan near their hand and they'd snatch it back, embarrassed, as if their arm had gone behind their back and made a decision without them. It made them feel like a passenger in their own body — like the real them was slow, and some other thing was in charge.

An old glowing elder had found them once, sulking, snatching their own hand toward a candle and yanking it away, over and over, furious.

"You're angry at the fast part," the elder said. Not a question.

Flicker had nodded, miserable. "It doesn't wait for me. It just does stuff."

The elder held a warm palm near the candle and let their own hand flinch back. "That's a good little servant, that fast part. It's not ignoring you. It's protecting you — it moves before you can, on purpose, because burning is quicker than deciding." They smiled. "Your body built a shortcut. The message hits your hand and comes straight back without even bothering the top of your head. Not because you're slow. Because this is faster, and being fast is the whole job."

Flicker had stopped, hand mid-yank. The fast part wasn't stealing from them. It was on their side. It was so on their side it wouldn't even wait around to be thanked.

That was the day the flinch stopped feeling like a stranger and started feeling like a friend who never left.

They walked into BioForge at twelve, still glowing, still watching every branch and thread in the place.

The mentor who ran the labs met them at the door — an unhurried old creature with a slow voice. No test of strength. Just one thing set on the bench: a smooth grey model of a single nerve cell, long and trailing, with a tiny gap at its end.

"Tell me what this does," the mentor said.

Flicker didn't answer with words. They touched one end of the long cell. A ripple of amber light ran the whole length of it, reached the gap, hesitated — then leapt the gap in a little chemical shimmer and lit up the next cell along. Flicker touched it again. Again the ripple, the leap, the light.

"It carries the message," Flicker said. "All the way down the long part — that's the axon. Then it hits the gap. The little bridge, the synapse." They made a leaping motion with two fingers. "The message can't just jump the gap by itself, so it throws a chemical across, and the chemical carries it to the next one. Ping, leap, ping, leap. Your whole body is millions of those, wired together."

The mentor watched the light travel, and was quiet a while. "You belong here," they said.

Flicker's workshop filled up fast, because a lab full of glowing wires is hard to walk past.

A tall kid slouched in one afternoon, unimpressed. "My teacher says my body's basically a computer," they said. "Wires and signals. That's it. That's kind of sad."

Flicker didn't argue. They handed the kid a soft rubber mallet and pointed at their own knee. "Tap it. Right below the kneecap. Not hard."

The kid tapped. Flicker's leg kicked out on its own.

"Did I decide to do that?" Flicker asked.

"...No?"

"Right. That message never even went up to my brain. It hit my spine, turned around, and came straight back to my leg. A shortcut — a reflex — so fast it skips the boss entirely." They wiggled their nose. "Some things you choose — jumping, kicking a ball, wiggling your nose. Your brain sends the order out to your fingers and toes, along all the branching wires, and they obey. But some things your body just handles — breathing, heartbeat, the flinch, the kick. You don't vote on those. Thank goodness. You'd faint trying to remember to breathe."

The kid tapped Flicker's knee again, and laughed when it kicked.

"So yeah," Flicker said, softer now. "Signals. Wires. Electricity, almost as fast as light, running from your brain and spine out to every scrap of skin. That part is like a computer." They tilted their head. "But here's the thing I won't let anybody skip. You're not sad or happy because of wires. The wires carry it — they don't decide it. What you feel, what you've been through, who's kind to you — that's bigger than any signal. Your body's the messenger. It was never the whole message."

The kid stopped tapping and just looked at them.
