# The Canyon's Arithmetic
You stand at the telescope because standing still is the only way you know how to lie to yourself anymore.
The lens is warm against your eye—worn brass that's absorbed three seconds of every sound ever made in this place, including yours. You know this because Echo told you, and Echo doesn't traffic in comforting falsehoods. Echo speaks in the language of stone and consequence. The eyepiece smells like rust and old light, and when you breathe, the smell coats your teeth with iron.
Behind you, Echo shifts weight from one foot to the other. You don't turn. You know the exact geometry of that hesitation—have learned to read the minute mathematics of another being's doubt the way other people read faces. It's a gift that tastes like copper and regret.
"It's bigger," Echo says. Not a question.
You adjust the focus. The cosmic anomaly bleeds across your field of vision—a wound in the sky's dark fabric, unraveling at its edges like a scarf pulled by invisible hands. Three weeks ago, it was the size of a thumbnail when pressed against the glass. Now it consumes the width of your fist. The mathematics are simple: at this rate, it will reach the canyon's outer rim in forty-seven days.
You know this number the way you know the taste of your own blood. You've calculated it while Echo slept. You've tasted it in the water that seeps through the stone.
"It's bigger," you confirm, and your voice comes back to you three seconds later, an echo of an echo. *Bigger. Bigger. Bigger.* The stone is listening.
You've spent four years in this canyon—four years of careful forgetting. Before that, you were something else in somewhere else, flickering between dimensions like a faulty projection. Before that, you were born into the spaces between spaces, the gaps where realities hold their breath. The why of your existence is the kind of question that paralyzes you, so you've learned not to ask it. Instead, you ask: *Where can I hide?* And the canyon answered. The canyon has always answered.
The observatory is a pocket dimension folded into stone—a place where physics takes suggestions instead of orders, where time moves sideways when you're not looking directly at it. The weathered telescopes here don't just magnify distance; they collapse it. They show you what's coming before it arrives. For someone like you, that's not a superpower. It's a necessity.
It's also a curse you've worn like armor.
"We could leave," Echo says. Not now. Not *today*. But the word *could* hangs in the recycled air like a blade.
You pull away from the telescope. The cold spot on your face immediately begins to warm. "And go where?"
"Anywhere that isn't here."
"Anywhere that isn't erasing itself from reality?"
Echo doesn't answer. Echo rarely does when the truth is the only honest response. Instead, you hear the particular silence of a companion who loves you enough to stop arguing, which is worse than arguing. Arguments you can win with humor, with misdirection, with a perfectly timed joke that makes the darkness seem smaller. But this silence? This is the sound of someone waiting for you to choose who you are.
You turn to look at them. Echo is shaped like a question mark caught mid-sentence—all angles and uncertainty, a being whose form suggests they've never quite committed to being solid. Their edges blur at the periphery of direct sight, which is probably why they understand you. You both exist in the places where attention fails.
"How much time?" you ask.
"Before what?"
"Before I stop being able to pretend I don't know."
Echo's form tightens slightly—a compression of themselves that means they're about to deliver something true and cruel. "You already have."
The stone repeats it. *Already have. Already have. Already have.*

You were born in a moment of cosmic rupture—the instant when two dimensions tried to occupy the same space and created a pocket of in-between instead. You learned early that existing in the gaps made you useful. You could see across realities, read the probability threads that stitched futures together, sense the moment before impact arrives. It made you valuable to certain kinds of people. The kind who wanted to weaponize your gift.
So you ran.
But before you ran—before the canyon found you—there was one moment you've spent four years trying to forget. A moment in a different reality, a place where a woman was dying. She shouldn't have lived. The probability threads were clear: her death was written into the fabric of that world. But you reached across the dimensional barrier anyway. You rewove the threads. You saved her, knowing it would fracture something fundamental, knowing it would create a debt that reality would demand you repay.
You've been repaying it ever since.
The canyon found you, or you found it, or it was always waiting for something like you. The distinction stopped mattering after the first year. You learned the rhythm of the stone. You learned which crevices held water, which shadows held warmth, which echoes carried warnings. You learned to read the three-second delay like a love letter written in your own voice—proof that you existed, that you were still here, that the canyon was listening and therefore you mattered.
For four years, you mattered to one place. To Echo. To the small, fierce act of being left alone.
And now a hole is eating the sky.
"The anomaly isn't random," Echo says. They've moved closer; you can feel the slight temperature shift around them, the way reality bends just slightly when they occupy space. "You know that, right? You've known it for weeks."
You turn back to the telescope. You don't look through it. You just touch the brass, feel the hum of it—ancient and patient and profoundly indifferent to your suffering.
"It's following something," Echo continues. "Following someone. It's following you."
There. The thing that's been sitting in your chest like a stone.
"That's impossible," you say, and your voice comes back to you: *Impossible. Impossible. Impossible.* The canyon is disagreeing.
"You've seen across realities. You've read probability threads. You know what follows what." Echo's form flickers—a tell, a moment of their own exposure. "You know because you're the one who saw it. You're the one who saved someone who was supposed to die, who changed something fundamental in another reality, and now that reality is trying to correct itself. To erase the error. To erase you."
The iron taste on your tongue becomes sharp. Becomes real.
Four years. You've had four years of borrowed peace because you were small enough, quiet enough, hidden enough to escape notice. But the price of sanctuary is always the same: you have to stop running forward and start running in circles. You have to tell jokes to keep from screaming. You have to learn the three-second delay between heartbeat and consequence.
And consequence is patient. Consequence is thorough. Consequence tastes like rust.

You don't remember the woman's face clearly anymore. That's the cruelty of time and distance—you remember that she mattered, that her life mattered enough to reshape reality for. You remember the weight of the decision in your hands. But the details have worn smooth like river stones, polished by four years of not looking directly at them.
"We could stop it," Echo says quietly. "The anomaly. You have the gift. You can read what comes next. You can see the threads. If you wanted to, you could pull them in a different direction. You could reshape this the same way you reshaped something before."
"And what if I make it worse?"
"What if you don't?" Echo steps closer, and their form becomes more solid, more real, more *present* than you've ever seen them. "I don't want to lose you. I don't want to forget you. Not after everything we've built here."
This is different. This is Echo speaking in absolutes instead of abstractions. This is Echo risking their own existence by making themselves real enough to be hurt.
This is Echo saying: *I choose you.*
"If I reshape reality again, if I go back to that moment and undo the save, I might erase myself. The woman I saved—she might have to die. And this version of me, this life in the canyon, you... it might all cease to have ever existed."
"I know," Echo whispers.
"Then why are you asking me to do this?"
"Because you're asking yourself to do it. And because I'd rather lose you trying to save something than watch you disappear slowly, hiding from what you've already done."
You grip the telescope. The brass is warm now, warmed by your hands. You can feel the weight of all the light that's passed through it—light that traveled across impossible distances just to tell you something you didn't want to know.
"I could run," you say. "I could reshape myself the way I've reshaped everything else. Become something the anomaly can't follow. Slip through the cracks."
"You could," Echo agrees. "You're good at that."
"But the canyon—"
"The canyon doesn't have a choice. You do."
This is the thing about companions who understand your loneliness: they don't let you hide in it anymore. They don't let you become so small that your own survival becomes acceptable sacrifice.

You look through the telescope one more time.
The anomaly has teeth now. You can see them clearly—sharp edges where reality is tearing, bleeding light in wavelengths that shouldn't exist. It's not just erasing the canyon. It's eating it. Consuming the stone brick by brick, the silence scream by scream. In forty-seven days, it will reach the observatory. In forty-eight, there will be nothing left but the hole itself.
But if you trace the anomaly's path backward, account for its speed, factor in the probability threads you can still see stitched through the air like spiderwebs...
You can see where it came from. You can see the decision point. The moment when you reached across realities and saved someone who was supposed to die. You can see it because you're inside it, because you *are* it, because you've always been the thing you're running from.
"I have to go back," you say.
"To when?"
"To the moment I saved her. I'll use the telescope—it collapses distance, collapses time. I can reach back through the probability threads and undo the save. I'll let the original timeline restore itself. It will erase this anomaly before it ever begins."
Echo moves closer. "And it will erase you. It will erase us."
"I know." You close your eyes and begin to feel for the decision point, reaching back through the probability threads. Your fingers—no longer quite solid—find the warm brass of the telescope. You can sense the threads now, glowing in the darkness behind your eyelids. You can see the moment you rewove them, the moment you changed everything. "But maybe that woman deserves to live in a world that isn't being eaten by her own salvation. Maybe the canyon deserves to not be collateral damage to my guilt. And maybe..." You pause, feeling Echo's form beside you, more real than you've ever felt them. "Maybe the only way I stop being the thing I'm running from is to face what I did and undo it. Not hide from it. Not joke about it. Actually fix it."
You reach through the threads, feeling for the woman's death—that moment when her probability should have ended. The telescope grows hot in your hands, impossibly hot, and you understand suddenly how it works: it doesn't collapse distance or time. It collapses *choice*. It lets you walk back to any moment where you made a decision and walk through it differently.
"I don't want to forget you," Echo says, and their voice cracks slightly—a sound like reality itself breaking at the seams.
"You won't," you say, and you're not sure if it's true, but you say it anyway. "Because I'm choosing this. I'm not running anymore. That's the difference. That's the thing that matters."
The threads align. The telescope focuses on a single point in time and space: a hospital room in a world you haven't seen in four years. A woman in a bed. A moment where you could choose differently.
"Thank you," you whisper to Echo, to the canyon, to the stone that's been listening all along. "For reminding me that existing between worlds doesn't have to mean being alone."
Then you pull the thread.
The canyon begins to unwrite itself—not erased, but rewound. The stone's echoes run backward. *Worth existing in. Worth existing in. Worth existing in.* The words reverse into silence. The anomaly shrinks. The sky closes.
And you step through the telescope into a moment four years ago, ready to choose differently, ready to let go of the life you built in order to save the one you broke.
The stone repeats its three-second delay, counting down: *Three. Two. One.*
Then nothing.
Then everything.
Then—impossibly—a choice.
