The Weight of Light

Summary:

Caitlyn Kiramman was always meant for more—for Piltover, for greatness, for a life where everything had a place, everything made sense. Vi was never supposed to be part of that equation.

They were young when they first met. They weren't dating, not really. Gravity is the reason we fall, Caitlyn had said to her. But Vi knows now—there are other forces, unseen, inescapable. Light bends under gravity. Even the brightest things carry weight. And Caitlyn had always been light to her.

Years later, Vi sees Caitlyn’s name on the news. Caitlyn, who has been in control of everything, is in a car crash. Twisted metal, shattered glass, sirens wailing into the night. By the time Vi reaches the hospital, they’re already fighting to keep Caitlyn alive. She watches from the ER doorway as doctors force air into Caitlyn’s lungs, as her heart monitor flatlines, as they shock her back to life.

Vi doesn’t go inside Caitlyn's room. Maddie does. The fiancée. The woman Caitlyn chose.

Vi should leave. She should let go. But some things never stop moving, even when they should. Even light, when it’s close enough to the edge, can’t escape.

Chapter 1: Prologue: Maximum Impact

Chapter Text

The rain smears the city into a trembling mirage, streaks of red, gold, and white bleeding across the windshield like paint rinsed from a brush. The wipers drag across the glass, slow, labored, as if each stroke is a struggle against the downpour. They clear only glimpses of the night before the water rushes back in, swallowing everything whole. 

The hum of the engine is steady beneath her hands, but her pulse is not. It hammers, erratic, a nervous staccato in her throat. The highway stretches ahead, slick and black, its painted lines dissolving under the weight of the storm. She knows she should slow down, but she doesn’t. She knows she should pull over, take a breath, but she won’t.

Her fingers ache where they grip the wheel. White-knuckled, locked in place. The pressure of bone against bone. Her body is rigid, braced against something unseen, something that has been pressing into her for far longer than this drive. The weight in her chest is unbearable tonight, heavier than it was this morning, heavier than it was when she stepped into her car and left everything behind. Her ribs feel too tight, as if they might crack under the strain of holding her together. 

She should focus on the road, on the treacherous slick of asphalt beneath her tires, but her eyes keep flicking to the passenger seat. To the phone lying face down. The notification light pulses in slow, rhythmic flashes. A heartbeat outside of her body. A wound trying, and failing, to close.

She doesn’t check. She doesn’t have to.

A name that unravels her from the inside out. A name that tastes like regret. A name that feels like the moment before impact, when you know you’re going to crash, and there’s nothing left to do but brace for it.

She should have ignored it. Should have silenced her phone the way she’s tried to silence the thoughts that always come back to her. Most nights, she does. Leaves the message buried beneath others, lets it sit there like a wound she refuses to touch. But tonight, the itch was bad. Bad enough that she gave in. Bad enough that she read it again.

It’s not new. The message wasn't even in her recent message list. But it lingers at the top of her messages, pinned there by muscle memory, by habit, by something in her that refuses to let go. A single line, one she’s read over and over, one she’s spent too many nights staring at until the words blurred.

Congratulations, Cupcake.

She told herself she wouldn’t read it again. That she’d stop torturing herself with the things she can’t change. But tonight, she tapped the thread open anyway, let the words sink into her like rain through cracked pavement.

It’s nothing. It’s everything. The casual weight of something that used to belong to her, now placed carefully at a distance. A kindness, or maybe a cruelty. She doesn’t know which is worse.

Her foot presses harder on the gas.

The engine roars, drowning out the rain, the wipers, the heartbeat in her throat. The car surges forward, faster now, too fast for a night like this, but she welcomes it. The world outside her window is a blur of wet neon and slick pavement, buildings rising and falling like faceless ghosts. The city feels endless, vast, but her vision narrows to a pinprick, her mind shrinking to the moment Vi’s name filled her screen and sent her hurtling backward into the past.

She shouldn’t have looked.
She shouldn’t have cared.
She shouldn’t still—

The wheels slip.

Impact is inevitable.

In mechanics, impact is when two bodies collide.
During this collision, both bodies decelerate.
The deceleration causes a high force or shock, applied over a short time period.

—but she is not stopping, she is gaining momentum, she is gaining speed, she is gaining ground.

The car spins, hydroplaning across the black asphalt, but she does not stop. The back end swings wide, the tires screaming, but she does not stop. The guardrail hurtles toward her, rain-slick and gleaming like the edge of a knife, but she does not stop. The world tilts, buildings bending like reflections in a broken mirror. Her heart slams against her ribs. There is no slowing, no deceleration, no breath between before and after—only the sharp, brutal lurch of motion unchecked.

The force crashes into her. The shriek of metal contorting. The explosion of glass into a thousand tiny stars. The seatbelt carves into her chest, a restraint, a tether, a cruel attempt at holding her together when everything is already unraveling. Her head snaps back, the world inverting, flipping, twisting.

Her thoughts scatter like debris across the asphalt.

The taste of copper floods her mouth. Warmth trickles down the side of her face, slow, winding. Her vision flickers—light, dark, light again. The weight in her chest grows unbearable, pressing down, pressing in. The breath in her lungs is shallow, struggling. Every part of her is screaming, but she cannot hear it over the rush of rain against twisted metal.

She is not stopping. She is still moving. The wreck is in motion. The night is still swallowing her whole.

Outside the shattered windshield, the city distorts into a mess of color and motion. Sirens wail in the distance, curling through the rain like echoes of something already lost. The world spins, shifts, and does not let go.

And then—

Darkness.
