[NARRATOR: There is a kind of fear that only exists underwater — the fear of lungs that has started counting down without permission. Tonight, Tails learns that fear from the inside, alone, in the dark, with no one left to reach for.]
PART ONE: THE CURRENT'S CHOICE
The tunnel had torn Tails away from Locke with a violence that felt almost deliberate, water screaming past his ears in a black rush that stole every sense of direction he thought he understood. When it finally spat him out, he hit a shallow pool hard enough to lose his breath entirely, surfacing into a chamber lit by pale green moss and the low, patient hum of something waiting for him in the dark.
[TAILS' INTERNAL MONOLOGUE: I used to think being alone just meant nobody was around. I didn't know it could also mean being the only one left who has to be brave.]
"Locke?" His voice bounced off wet stone and returned smaller than he'd sent it out. Nothing answered. A shape uncoiled from the far end of the flooded chamber — a bulbous, propeller-driven capsule breaking the surface, Eggman visible behind its curved glass front, grinning even through the murk of disturbed silt.
"Well, well," Eggman's voice crackled, muffled and strange underwater. "The little fox, all on his own. No anomaly to hide behind this time." Tails' hands curled into fists beneath the surface, twin tails flicking with nervous energy he refused to let show on his face. "I don't need him standing next to me to fight you." "Bold words," Eggman said, "for someone about to drown."
PART TWO: THE FIRST BOMBS
The Egg Vortex's propeller roared to life, and the current it generated slammed into Tails like a wall, dragging him sideways past jagged rock outcroppings he barely avoided in time. He fought the pull with everything his tails could give him, spinning them into a blur that cut just enough resistance to keep him from being smashed against the stone.
Eggman's machine released the first bomb into the water ahead of him — a dull metal sphere sinking slow, a red light blinking steady beneath the surface like a countdown made visible. "Tails!" The shout came muffled through rock and current both, distant but unmistakably Locke's voice, somewhere above and to the left. "Tails, where are you?" "Down here!" Tails called back, though he doubted the sound carried far enough to matter. He didn't wait to find out. Whatever came next, he'd have to meet it alone.
The bomb detonated on its own timer, and the displaced water shot upward in a column with enough force to fling loose debris toward the surface far above. Tails watched it happen once, then twice more as Eggman dropped additional charges, cataloguing the pattern the way his mind always catalogued things when he was frightened — timing, force, trajectory.
Eggman released a second bomb, closer this time, clearly testing him. Tails held his position, counting under his breath, and when the detonation came, he was already moving — not away from the blast, but toward the rising column of water, timing his leap to the exact half-second the burst reached its peak. The water caught him and threw him upward like a closed fist opening. He broke the surface gasping, and slammed both feet into the Egg Vortex's hull before gravity could remember him. The capsule rocked hard, sparks spitting from a seam near its propeller housing. "Impossible!" Eggman's voice broke with real surprise. "You used my own bomb against me?"
"Copied it off your last machine," Tails shot back, treading water, stomach already heaving. "You should really stop building the same weakness into everything you make."
PART THREE: THE SECOND STRIKE
Eggman didn't waste time being embarrassed. The propeller spun harder, dragging Tails through a fresh current toward a field of jagged formations jutting from the chamber floor like broken teeth. He twisted through the gaps at the last possible instant, one tail-tip scraping stone hard enough to sting straight through the cold.
[TAILS' INTERNAL MONOLOGUE: Sonic would've done this without thinking twice. I keep thinking, and thinking, and thinking, and somehow I'm still here. Maybe that's its own kind of brave.]
Two more bombs dropped in quick succession, spaced closer together than before, clearly meant to overwhelm whatever rhythm he'd found. Tails forced himself to breathe evenly despite the burn already spreading through his lungs, tracking both spheres at once, weighing which burst would carry him higher and cleaner. He chose the second, angled slightly wide.
The explosion caught him off-balance, sending him spinning instead of straight upward, but he corrected mid-air with a sharp flick of both tails, adjusting his trajectory just enough to land another solid hit against the capsule's hull. Sparks cascaded downward through the water in slow, glittering arcs, dimming as they sank.
"You're improving," Eggman snapped, and it didn't sound like a compliment so much as an accusation leveled at the universe itself. "Make me stop," Tails said, and surprised himself with how much he meant it. The chamber's air pockets were thinning fast. Tails felt his vision blur faintly at the edges, lungs screaming louder now than his determination could quiet. One more hit. He needed exactly one more, and he wasn't certain his body had one left in it to give.
PART FOUR: THE LAST BOMB
Sensing the fox's exhaustion, Eggman went for overkill — three bombs released at once, spaced wide in a deliberate arc meant to leave no safe gap between them. "Let's see you calculate your way out of that," he said, smugness crackling through the speaker despite the damage already scarring his machine. Tails' mind raced through the geometry of it the same way it had raced through blueprints and broken schematics his whole life, hunting for the flaw nobody else would bother to look for. Three bombs. Three rising columns. If they detonated close enough together, at close enough range—
He didn't wait for the first one to fall. He swam directly into the center of the triangle they'd form and held his position there, forcing down every instinct screaming at him to flee.
The bombs went off almost simultaneously. The three columns of displaced water collided at the center point and erupted straight upward in a single massive geyser — carrying Tails with it, fast and high enough that for one weightless second he saw the entire flooded chamber spread beneath him like a map he'd finally, finally finished drawing. He came down on the Egg Vortex with both feet and his full weight behind them, and the hull caved inward with a shriek of failing metal.
"No — no, this is — full retreat!" Eggman's voice pitched into something close to genuine panic as the capsule sputtered, spun once on a dying propeller, and began sinking toward the chamber floor in a trail of bubbles and extinguishing sparks. Tails broke the surface gasping, treading water on legs that had nothing left to give him, and let himself laugh anyway — short, disbelieving, entirely real.
PART FIVE: WHAT HE CARRIED BACK UP
Locke found him twenty minutes later, hauling himself out of a side channel with his jacket soaked through and his ribs still aching from the Big Shaker's parting gift. "There you are." Relief broke across Locke's face so openly it looked almost painful to wear. "I heard explosions. I thought—"
"I handled it," Tails said, and something in the way he said it — steady, quiet, nothing at all like the frightened kid who'd first stared down a dimensional anomaly three days ago — made Locke stop mid-sentence to actually look at him. "Handled what, exactly?"
"Eggman's submarine thing," Tails said, wringing water out of his ears with the exhausted efficiency of someone who'd just done something enormous and hadn't fully caught up to it yet. "Bombs everywhere. Almost drowned twice. Beat it anyway." Locke studied him for a long moment — really studied him, the way a person looks at someone they're seeing clearly for the first time. "Alone."
"Alone," Tails confirmed, and didn't look away from it. "That's..." Locke searched for the right word and settled on the truest one available to him. "That's incredible, Tails." The fox ducked his head, but the small, proud smile he couldn't quite suppress said more than any answer could have managed on its own.
PART SIX: THE GUARDIAN, UNMOVED
They found Knuckles waiting near the surface exit, arms crossed, expression carved from something that hadn't cracked yet and had no intention of starting now. "You're both still alive," Knuckles said, flat. "Shame." "We're not your enemies," Locke said, tired down to the bone but steady regardless. "You'll figure that out eventually."
"I already know everything I need to," Knuckles said. "The doctor's told me exactly what you both are, and exactly what you're after." "Has he told you what happens once he doesn't need you anymore?" Locke asked quietly. Something flickered behind Knuckles' eyes — not doubt, not yet, just a flash of irritation at a question he didn't have a ready answer for. He turned without responding, vanishing back into the treeline, and neither Locke nor Tails moved to follow.
[LOCKE'S INTERNAL MONOLOGUE: I know how this ends between us, eventually. I've watched the shape of it play out in other worlds, other versions of this same betrayal waiting to happen. But knowing where a bridge leads doesn't make the distance any shorter to walk. He has to fall before he'll let us catch him.]
Behind them, deep in the ruins, the wreckage of the Egg Vortex sank the last few feet to the chamber floor, silt settling slowly over sparking metal — one more piece of Eggman's plan drowned, and one more piece of Tails quietly, permanently changed by having done it himself.
[NARRATOR: The guardian's trust will not come easily, and it will not come soon. It will come the way it always has — after betrayal finally shows him a face he refused to imagine, at a launch site not yet built, on a night not yet arrived. Until then, Locke and Tails have only each other, and a fox who just learned, alone in the dark, exactly how much weight he's able to carry on his own.]
