The Sixth Seat

The cabin felt smaller than Cassian remembered, which made no sense, because it was the same plane, the same six leather seats arranged three-and-three down a narrow aisle, the same oval windows framing the same darkening gold afternoon — and yet everything about it felt tighter now, pressurized, as if the walls themselves understood what was coming and had begun, quietly, to close in.

He took the same seat. Second row, aisle side, the window seat beside him empty because his mother had taken the row behind instead, close enough to reach him, her hand already finding his arm the moment she sat, fingers digging in with the same urgent pressure he remembered from a death that hadn't happened yet.

Bastian settled across the aisle, forcing cheerfulness into every word, asking Malcolm loud, friendly questions about flight time and cruising altitude that nobody in the cabin was actually listening to. Moira took her seat two rows back, silent, her hands folded tight in her lap, eyes fixed somewhere past the window that Cassian couldn't follow. And Zack sat directly behind the cockpit, exactly where Cassian remembered him sitting the first time, close enough to reach for Malcolm — for Zack, close enough to be reached by him — the moment the cabin door sealed and the engines climbed toward takeoff.

The sixth seat, at the very back, sat empty.

Cassian couldn't stop looking at it.

"You okay?" his mother whispered, close to his ear, and he made himself nod, made himself not tell her that his whole body had gone rigid with the certainty that somewhere between this tarmac and thirty thousand feet, that empty seat was not going to stay empty.

The plane taxied. The engines roared up through their register, and Cassian gripped the armrests hard enough that his knuckles went white, watching the ground blur and then drop away entirely, the airfield shrinking beneath them into a grey smear, and then they were up, properly up, banking gently west into a sky gone the color of a fresh bruise, exactly as it had before.

For the first few minutes, nothing happened. Nothing at all — just the ordinary hum of the engines, the small domestic sounds of a cabin settling into cruise, Bastian's forced conversation finally trailing off into silence, Zack's shoulders rigid in the seat ahead, watching the cockpit door the way a man watches a wound he already knows is going to open.

Cassian counted the minutes. Four. Six. Nine. Every second stretching, unbearable, and he understood, with a cold clarity, that this was the exact window his father had described — the eleven minutes of silence before the sound, the last stretch of ordinary time this family would ever share, if today ended the way every other version of it had ended before.

At the ten-minute mark, the cockpit door, which had been shut and latched since boarding, clicked softly open on its own.

Not swung open. Not slammed. Clicked — the small, deliberate sound of a lock releasing, as if someone inside had simply decided the time had come.

Zack was on his feet instantly, faster than Cassian had ever seen a person move, lunging toward the gap before it had fully widened, and Cassian was up too, unbuckled, half out of his seat, his mother's scream already starting behind him — and then the plane bucked, hard, a sudden violent drop that threw everyone sideways and slammed Cassian into the seatback in front of him, and through the widening gap in the cockpit door, in the strobing red wash of an alarm just beginning to sound, Cassian saw two things at once, both of them impossible, both of them true.

Malcolm was still alive. Slumped forward against the controls, breathing, a thin line of blood at his collar but not — not yet — the catastrophic wound Cassian remembered, the plane still level enough, still climbing enough, that whatever was happening hadn't finished happening.

And standing over him, one hand still gripping the back of the pilot's seat, face lit red and white by the strobing alarm lights, was a man Cassian had not seen in six weeks — thinner than he remembered, hollow-eyed, dressed in clothes that didn't fit him properly anymore, but unmistakably, achingly, his own father.

"Dad?" The word tore out of Cassian before he could stop it, disbelief and terror and a month of grief colliding all at once in a single syllable.

His father turned, and for one suspended second, father and son stared at each other across the width of a cabin coming slowly apart around them, and Cassian saw, in his father's face, not the calm menace he'd feared, not the cold calculation of a killer finally caught — but pure, undiluted horror, the expression of a man who had just realized, too late, exactly what position he'd been put in.

"I didn't do this," Tom Wintermere said, voice cracking, hands raised, empty, no blade in them at all. "Cassian, I swear to you, I didn't — I got on this plane to stop it, I got here as fast as I could, and he was already like this when I opened the door, I swear on your life I didn't—"

The plane lurched again, harder, and somewhere behind them Moira had begun, very softly, to scream a name Cassian still couldn't fully place, and Bastian was shouting something about the exit rows, and Karla's hands were locked around Cassian's arm hard enough to bruise, and through all of it, through the noise and the red strobing light and the ground beginning, terribly, to grow detail beneath them once again, Cassian's eyes found the one thing in that narrow, chaotic cabin that made his entire understanding of the last five days collapse and reassemble itself in a single, sickening instant.

A thin, bright line of red, freshly wet, on the cuff of Zack's sleeve.

Not his father's hands. Not Bastian's, not Moira's, not anyone Cassian had spent four desperate days suspecting and clearing and suspecting again.

Zack, who had wept over a cold coffee cup. Zack, who remembered the crash exactly as Cassian remembered it, who had held his own grief like a wound too tender to touch. Zack, standing closest to the cockpit door, closest to Malcolm, close enough — Cassian understood now, with a horror that swallowed everything else — to have been the only person in this entire cabin who had truly, geographically, always had the access to do what had been done.

"Zack," Cassian said, and his voice came out strange and small, swallowed almost entirely by the shriek of the alarms. "Zack, your sleeve—"

Zack looked down at his own cuff, at the blood there, and something moved across his face that Cassian had never seen before — not guilt, not triumph, but a terrible, dawning grief, the expression of a man watching the last thread of his own innocence come apart in front of a boy who had trusted him.

"It's not what you think," he said, and his voice had gone hollow, stripped of every warm, practiced note it had ever carried. "Cassian — I need you to listen to me, right now, because I am the only person on this plane who can still stop what's about to happen, and I need you to trust me for exactly the next ten seconds even though I understand you have no reason left to."

The ground kept rushing closer. The alarms kept screaming. And Cassian, frozen between his father's raised, empty hands and Zack's bloodied sleeve, understood that whatever he chose to believe in the next ten seconds was going to decide, finally and completely, whether any of them survived to see this Friday end.
