The abandoned warehouse groaned around them every time the wind hit the rusted metal siding. Rain hammered the roof hard enough to drown out the distant highway, leaving the building wrapped in a cold, echoing kind of silence between every crash of thunder.

Dust floated through weak beams of light cutting in from broken windows high above.

Dean stood near the entrance, gun lowered but tense, eyes locked on Sam across the warehouse floor.

Bobby hovered near one of the support beams, jaw tight beneath his ball cap.

And Sam—

Sam looked wrecked.

Pale. Sweating. Breathing too fast.

The second your boots crossed into the warehouse, Sam’s head snapped toward you so sharply it almost looked painful. For one brief moment relief flickered across his face.

Then Lucifer appeared beside you.

At least, that’s what Sam saw.

Lucifer leaned casually against a crate with that infuriating grin stretched across his face, suit immaculate despite the filth around him.

“You brought the girlfriend?” Lucifer mocked. “Aw. That’s adorable.”

Sam staggered back a step, gripping the handgun tighter.

Dean immediately noticed. “Sammy,” he warned carefully. “Easy.”

“You don’t see him?” Sam asked, voice cracking.

Lucifer laughed softly. “Oh, this is getting embarrassing.”

Your heart twisted at the sight of Sam unraveling in front of you. This wasn’t the Sam you knew. Not really. This was exhaustion and trauma and hell clawing its way through the cracks in his mind.

“You’re okay,” you said gently, taking a cautious step closer. “Sam, look at me.”

But Sam’s eyes weren’t really on you.

They were fixed on Lucifer.

Lucifer stepped closer to you in Sam’s hallucination, smiling wider. “C’mon, Sam. Shoot me.”

Dean slowly moved forward. “Sam, put the gun down.”

“Don’t!” Sam shouted, swinging the weapon toward Dean before jerking it back toward Lucifer again. “Stay back!”

The gun shook violently in his hand.

Your chest tightened seeing tears building in Sam’s eyes. Fear. Confusion. Guilt. He looked trapped inside his own head.

“You know I’d never hurt you,” you whispered.

Lucifer tilted his head mockingly. “Funny thing is? You already did.”

Sam flinched hard like he’d been slapped.

You took another slow step forward despite Dean reaching out slightly like he wanted to stop you.

“Sam,” you said softly, voice steady even as your heart pounded. “It’s me.”

Lucifer suddenly lunged in Sam’s vision.

Sam reacted instantly.

The gun fired.

The deafening crack exploded through the warehouse.

For a second nobody moved.

Then burning agony ripped through your stomach.

A sharp gasp left your lips as your hands instinctively clutched the spreading warmth soaking through your shirt. Your knees buckled almost immediately.

Sam’s face went completely blank.

The gun slipped from his fingers and clattered across the concrete.

“No…”

You hit the ground hard, pain radiating through your entire body while blood spread between your fingers.

Dean cursed and rushed forward instantly, dropping beside you while Bobby sprinted for the med kit stashed near the trucks.

But Sam couldn’t move.

Lucifer was gone.

Only you remained.

Your small frame curled slightly against the concrete floor, brown hair falling into your face, hazel eyes wide with shock and pain. Blood stained your shirt crimson beneath trembling hands.

Sam looked like the world had just ended.

“No, no, no…” he choked out, stumbling toward you on shaky legs. “Baby—”

His voice broke completely.

The second he dropped beside you, his hands hovered uselessly over the wound, terrified to touch you and somehow make it worse.

Your breathing came shallow and uneven.

Sam’s entire body shook violently.

“I didn’t—” His words collapsed into panic. “I thought—I saw—”

Dean grabbed Sam by the shoulder hard. “Get it together, Sam!”

But Sam could barely hear him.

All he could see was the blood.

Your blood.

And the horrifying realization that after everything Hell had already taken from him…

He’d just shot the person he loved most.
