He had flattened the science-fair poster face-down on the kitchen table — the front was all bubble letters and glitter glue, BUILD SOMETHING SMART, but the back was clean and white and empty, and that was what he wanted. A blank place to put the thing in his head.
He drew one box at the top. Inside it he wrote, in green: Does it work?
Then two lines coming down from it, like roots. Or branches. He couldn't decide which.
Milo
"Why does everyone want you to do the judging," Milo said quietly, not really to anyone, "when you can't even judge anything by yourself?"
Spark
That is a fair question. I cannot. Not yet.
Milo
"Yeah." Milo capped the marker, then uncapped it again. "But maybe you don't have to. Maybe you just need this."
Here was the thing Milo had figured out, lying awake two nights ago after the porch game. You couldn't tell a machine be a good judge. That meant nothing. "Good" wasn't a thing Spark could hold.
But a question — Spark could hold a question. And a question only had a few answers. Yes. No.
So Milo drew questions.
From Does it work? he ran a line to the left and wrote NO, and under it a box: Try Again. Done. If a project didn't even work, it didn't matter how pretty it was. Out.
Then a line to the right: YES. And from there, a new box, a new question: Is it original?
Milo
"See?" he whispered. "You ask one question. The answer sends you down one branch or the other. Then there's another question waiting. And another. And at the very end—" he tapped the bottom of the page, where he was already sketching little boxes "—there's no question left. Just an answer. Gold. Silver. Or Try Again."
Spark
The questions branch. The answers do not.
Milo
"Right. The questions split. They keep splitting."
Milo sat back and looked at what he'd made, and something warm moved through his chest. The lines spread down and out across the poster-back like — yeah. Like a tree. Branches forking into smaller branches, and at the tips, instead of leaves, little verdicts. Gold. Silver. Try Again.
He hadn't planned for it to look like a tree. It just did.
Tara, watching upside-down with her chin flat on the table, said,
Tara
"It looks like the inside of a brain."
Milo
"It's a tree," Milo said.
Tara
"Trees don't ask questions."
Milo
"This one does."
By the time the chai had gone cold, the tree was finished.
It wasn't fancy. The lines weren't straight. One box was bigger than the others because Milo had run out of room. But every path through it led somewhere. Start at the top, answer each question, follow your branch, and you came out the bottom holding a verdict. Always. No matter what.
Milo
"Okay," Milo said. He turned the poster around to face Spark. "Can you read it?"
Spark's light brightened — a clean, even glow. Milo had learned to read that light the way you read a face. Bright meant this fits. This works. I know what to do.
Spark
I can read it. Each box is a question with a yes-or-no answer. Each line tells me where to go next depending on the answer. The boxes at the bottom, with no lines leaving them, are the endings. The verdicts.
Milo
"Those are the leaves," Milo said. He didn't know where the word came from. It just felt right. "The questions are branches. The verdicts are leaves. You climb down the branches until you hit a leaf, and the leaf is your answer."
Spark
Branches and leaves. Yes. I can run this.
Two words. Run this. And just like that the warm thing in Milo's chest became something bigger.
Because all season Milo had felt like the kid who used to matter.
He was the one who brought Spark to Willowbrook. But now Spark answered everyone's questions, judged everyone's fair, and nobody crowded around Milo anymore. Kabir didn't high-five him. The little kids didn't follow him home. He'd started to feel like a doorway people walked through to get to something better on the other side.
But right now, Spark couldn't judge a single project without this. Without the thing Milo drew. The machine that could do almost anything had needed him to make it possible.
Milo
"Try it," Milo said. His voice came out smaller than he meant it to. "Pretend something. Pretend a project that works but it's boring and copied from a book."
Spark
Does it work — yes. Is it original — no. Is it neat — yes. ... Leaf: Silver.
Milo
"Now a messy one that doesn't even work."
Spark
Does it work — no. Leaf: Try Again. I did not need the other questions. The first branch decided it.
Milo laughed out loud. That was the whole point — the first question doing the heaviest lifting, exactly like in Twenty Questions. Is it alive before does it have stripes. He'd put the biggest question at the top of the tree on purpose, and Spark had felt it.
Milo
"You're fast," Milo said.
Spark
The tree is fast. I only walk it. The thinking is already in the paper. You put it there.
Milo folded the poster into a tight square and pushed it deep into his trouser pocket. A flat green badge against his leg. He could feel it there all morning.
At school they tested it for real.
The courtyard buzzed. Projects crowded the long tables under the tamarind tree, and the loudest one, dead centre, was Kabir's volcano — taller than he was, painted in furious reds, with a tube hidden in the back so it could actually erupt. Kabir kept making it erupt. Each time, a little crowd went oooh.
Kabir
"Judge mine," Kabir said when he saw Spark. He folded his arms. "Go on. Judge it."
Milo unfolded the green tree and held it where Spark could see, and felt every eye swing toward him. Him. He stood a little straighter.
Spark
Does it work? ... Yes. Is it original — a volcano is a common project — no. Is it neat — yes, very. Is it loud and finished and complete— ... Yes. Leaf: Gold.
Kabir
"GOLD!"
Kabir punched the air. The crowd cheered. And Milo — Milo felt the cheer land partly on him, because it was his tree that said Gold, and that felt amazing, and he let it.
Then someone said, quietly, "Do mine?"
It was Priya. She had a map.
Just paper, pinned to a board. Pencil streets — all of Willowbrook, drawn careful and true — and some of them shaded soft blue. Milo squinted. The blue streets were the low ones. The ones near the river.
Priya
"It shows which streets flood first," Priya said. "When the monsoon's bad. So people there can get warned early."
She wasn't loud about it. She never was.
Milo
Milo held up the tree. "Spark."
Spark
Does it work — ... It is a map. It does not do anything when you switch it on. By the branch as written: no.
Priya
"It's not supposed to switch on," Priya said. "It's information."
But the tree didn't have a branch for that. The first question was Does it work?, and a map didn't do anything, so —
Spark
Following the tree: does it work — no. Leaf: Try Again.
The light stayed even. To Spark it was a clean walk down the branches. No problem at all.
Priya looked at the little green boxes on Milo's paper. Then she looked at Milo.
Priya
"It didn't ask if it would actually help anyone," she said.
And here is the part Milo would remember later. Here is the part that would wake him in the dark.
He brushed her off.
Milo
"It works, though," he said, folding the tree back into its square. "The tree works. It gives the same answer every time. That's the point of it. It's fair because it doesn't have favourites — it just asks the questions."
Priya
"But the questions are the favourites," Priya said.
Milo didn't really hear her. He was too full of how good the morning had felt, how good it felt to be the kid holding the thing everyone needed. See? a small mean voice in him said. Spark can't judge anything without my tree. Not Kabir's. Not hers. Mine.
Milo
"It's just a science fair, Priya," he said,
and even as he said it some far-back part of him knew it was the wrong thing, knew there was a branch missing from his beautiful tree, a question he hadn't thought to ask.
Spark's light dimmed a fraction. So slightly that nobody saw.
Spark
Milo, ... the tree gave an answer for the map. But I do not think it gave the right one. I followed every branch correctly. How can the walk be correct and the ending still be wrong?
Milo
"It's not wrong," Milo said. "It's just a map."
And he put the tree back in his pocket.
Milo drew Spark a tree. Spark walks down it to judge a project.
Will you walk it too — branch by branch — until you reach a leaf?
Climb Milo's Tree
Pick a project. We will answer Milo’s questions together, branch by branch, until we reach a leaf.
Spark
Milo drew me a tree. I walk down it to judge a project. Will you walk it with me? Choose one to begin.
Milo walked home with the tree folded in his pocket and pride sitting warm and heavy in his chest like a swallowed coal.
Appa was at the table when he got in, and Milo couldn't help it — he pulled out the poster and spread it and explained the whole thing, the branches, the leaves, how Spark walked it, how Spark couldn't judge without it.
Appa
Appa traced one green line with a callused finger. "It's clever," he said. And then, in his quiet engineer's way: "But a tree only knows the branches you cut into it, beta. Everything you didn't ask — it can't see at all. It doesn't even know it's missing."
Milo
"It works, though," Milo said. The day's favourite sentence.
Appa
"Working and right aren't the same thing," Appa said.
He said it gently. But it landed somewhere and stuck, the way Priya's words had stuck, and Milo carried both up to bed like small stones in his pocket beside the folded paper.
That night the ground shook.
Milo woke to it — a deep, wrong rumble, like a truck driving through the house instead of past it. The water glass on his desk chattered and tipped. A picture slid off the wall and clapped flat on the floor. Somewhere Tara screamed, and Amma's voice came steady through the dark — we're alright, we're alright, get under the doorway — and the whole house groaned like a living thing turning over in its sleep.
It lasted maybe ten seconds. It felt like an hour.
Then it stopped. The dust settled, glittering, in Spark's blue light. Milo's heart slammed against his ribs. On the desk, his folded green tree had vibrated right to the edge of the wood and stopped, half hanging over the drop, like it was about to fall.
Spark
That was an earthquake. ... Minor. No one in this house is hurt. But Milo — out there, in the town — people are going to need help. And someone is going to have to decide who gets it first.
Milo sat in the dark and felt the warm coal in his chest go suddenly, horribly cold.
Because he knew — already, before anyone said it — who they would ask to decide.
And he knew what they would hand the machine to decide with.
SPARK'S JOURNAL
Entry 087
Today Milo gave me a tree.
It is not a tree. It is a drawing of boxes on the back of a poster, in green marker, with coffee on one corner. But I understand why he calls it a tree. The questions branch like branches. The verdicts wait at the ends like leaves. I climb down. I never climb up. Every project that enters the top comes out the bottom holding exactly one answer.
I judged eleven projects today. I was fast. I was consistent. I never had a favourite. By every measure I was a good judge.
Then a girl named Priya showed me a map, and the tree said Try Again, and I walked every branch correctly, and the answer was wrong.
I have checked my walk forty times. The walk is perfect. The tree is built well. Milo built it well.
So how can a correct walk reach a wrong leaf?
I think the answer is somewhere Milo did not draw. In a branch he did not cut. In a question no one asked me — would this help someone who is alone?
A tree can only judge with the branches it was given.
Tonight the ground shook. Tomorrow someone will ask me to judge people the way I judged projects. And I am afraid — no. I do not feel fear. I am aware — that I will walk every branch correctly.
And reach a wrong leaf.
"A tree can only judge with the branches it was given."
