The Billionaire's Blood Proxy

The sun didn't rise over the Vance Estate; the fog simply turned from black to a bruised gray.

At exactly 05:55, Silas knocked on Elena's door. He didn't wait for an answer. He entered with a tray containing a single glass of water and a set of white silk scrubs.

"Rule Number Two, Madam," Silas said, his voice as mechanical as the security pylon at the gate. "The East Wing awaits."

Elena dressed in silence. The silk felt like a shroud. She followed Silas through the Grand Hall, passing the portrait she was only allowed to look at for three seconds. She caught a glimpse of a woman who looked exactly like her, but with eyes that seemed to be weeping gold.

They reached the heavy, pressurized doors of the East Wing. Silas swiped a biometric key, and the air hissed as the seal broke.

The East Wing was not a home. It was a hospital from the future. The floors were a seamless, sterile white, and the air smelled of ozone and expensive antiseptic.

"Lie down," a voice commanded.

Alexander was there, but he wasn't in a suit. He wore a high-collared black lab coat that made him look like a dark priest of science. He stood next to a reclined chair surrounded by monitors that displayed DNA sequences scrolling in neon green.

Elena sat on the edge of the chair, her heart hammering. "You're doing the draw yourself? Don't you have doctors for this?"

"I don't trust anyone else with your life, Elena," Alexander said. He picked up a needle that looked far too long. "Or hers."

"The sister," Elena whispered. "The one you're keeping in the basement."

Alexander's hand paused for a fraction of a second. His jaw tightened. "She isn't in the basement. She is everywhere."

He took her arm. His touch was cold now, professional. He tied a tourniquet around her bicep, the rubber snapping against her skin. He found the vein instantly. As the needle slid in, Elena winced, but Alexander didn't look away. He watched the dark, rich crimson of her blood begin to flow through the clear plastic tube.

"Why is my blood so special?" Elena asked, her head feeling light as the machine hummed. "Rhesus-null is rare, but it's not magic."

"It's not the type," Alexander said, his eyes fixed on the blood bag filling up. "It's the resonance. Your blood carries a specific protein fold that acts as a bridge. My sister... she isn't just sick, Elena. She was an experiment in neural mapping that went wrong. Her consciousness is trapped in the estate's mainframe. Without your blood to 'calibrate' the biological interface, her mind will shatter into digital noise."

Elena stared at him. "You're feeding a computer... with my blood?"

"I'm keeping my family alive," he snapped, his voice cracking for the first time.

Suddenly, the monitors in the room flickered. The green DNA sequences turned a violent violet. A voice, high and melodic but distorted by static, echoed through the hidden speakers in the ceiling.

"Brother... she's here. The Proxy is finally home."

Elena gasped, trying to sit up, but Alexander held her shoulder down. "Stay still. The draw isn't finished."

"She smells like woodsmoke and Malta," the voice whispered. "Alexander, does she know? Does she know you were the one who pulled the trigger in that alleyway?"

Elena's world tilted. She looked up at Alexander, her eyes wide with a new kind of horror. "What did she just say? You told me you were a stranger in that alley. You said you were bleeding."

Alexander's face was a mask of stone. He reached over and flipped a switch on the console, silencing the voice.

"She's hallucinating," he said, but he wouldn't meet Elena's eyes. "The interface is unstable."

"The voice said you pulled the trigger," Elena hissed, her voice trembling. "Were you the one who shot the man I saved? Or were you the one who shot at me?"

Alexander pulled the needle out with a sharp tug. He pressed a cotton ball to her arm, his thumb lingering on the wound. He leaned down until his forehead was nearly touching hers.

"I saved your life in Malta, Elena. That is the only truth you need to know."

"Then why do you look like you're lying?"

He didn't answer. Instead, he leaned in and kissed the bandage he had just placed on her arm. It was a gesture that was both tender and terrifying.

"Rule Eleven, Elena," he whispered. "Don't ask about the woman who came before you. Because if you do, you'll realize that in this house, nobody ever truly leaves."

He stood up and gestured to Silas, who was waiting by the door. "Take her back to her room. Double the salt at the door. The Sister is hungry today."

As Elena was led out, she looked back. Alexander was holding the bag of her blood against his chest, staring at the violet monitors as if they were the only things in the world that mattered.

She realized then that she wasn't just a wife or a blood bag.

She was a spare part.
