Chapter 7 - The Confession in the Lab

The sterile hum of the fluorescent lights overhead felt oppressive, pressing down on the circular chamber like a physical weight. Clara took two steps backward, putting distance between herself and Mark as if he had suddenly transformed into a stranger. Her chest rose and fell in shallow, rapid gasps.
"You authorized it?" Clara’s voice cracked, the betrayal cutting deeper than any fear of Dr. Hayes or the strange machinery surrounding them. "You were the one who signed off on the human trials? The ones that erased the entire third shift?"
"I signed off on saving this timeline from collapsing under its own data weight," Mark replied, his voice chillingly calm, though his jaw muscles twitched. He gently set Leo down on the metal grating of the floor, and the toddler immediately walked toward the central terminal, his small fingers reaching out to touch the glowing keys without hesitation. "Clara, listen to me. What you remember as an explosion in Chicago wasn't an accident. It was an extraction."
"An extraction of what?" Clara demanded, her hands curling into tight fists at her sides, ready to strike if he moved toward her. "You destroyed lives! You wiped people from history books as if they were typos!"
"We wiped timelines that were bleeding into ours," Mark stepped toward her, his expression softening just enough to show the immense exhaustion etched into his features. "Every time we made a choice, a branch fractured off. If we didn't prune those branches, the core reality would have unraveled before Leo was even conceived."
"Leo..." Clara looked down at the toddler. Leo was typing fluidly on the terminal keyboard now, his small hands moving across the keys with the speed and precision of a seasoned systems engineer, despite never having touched a computer in his life. "What have you done to our son, Mark? Why is he connected to this system?"
"He isn't connected to the system, Clara," a new voice echoed from the shadows behind the cylindrical tanks.
Both Mark and Clara whipped around. Dr. Hayes stepped out from the amber glow of the liquid-filled glass tubes, his gray trench coat swaying slightly. He wasn't holding a weapon, but his hands were bare, and the palms were marked with intricate, glowing silver scars that pulsed in rhythm with the terminal screen.
"Dr. Hayes," Mark stepped in front of Clara and Leo, his body tense. "I thought you were scrubbed from the registry."
"You can't scrub a man who invented the ink, Mark," Hayes smiled, a thin, humourless expression that didn't reach his eyes. He pointed a finger toward Leo. "He’s not connected to the system because he is the system. The boy is the stabilization anchor for the entire branch we’re standing in right now."
Clara let out a choked sob, shaking her head violently. "No. No, he's just a baby. He's two years old!"

"In this branch, yes," Hayes said smoothly, taking another step closer. "In the primary branch, he’s thirty years old, and he’s the one who sent us back here to stop you from making the choice that ends everything."
