Mara Ellison paused outside her father's door, one hand on the frame, listening for signs of the man she remembered. The assisted living facility was quiet this early, its hallways filled with the faint scent of disinfectant and the occasional murmur of staff preparing for shift change. A television flickered somewhere down the hall, soft and distant.
She tapped lightly, then stepped inside.
Robert sat in his recliner by the window, a philosophy-of-mind book open in his lap. The spine had been bent so many times it looked close to tearing, margins crowded with his neat, looping handwriting from the years when he had taught philosophy, before Richard Vale persuaded him to help build a biotechnology company around questions they had once debated in seminar rooms. Morning light fell across his face, softening the deepening lines at the corners of his eyes.
He turned toward her and hesitated, as if searching for the right association.
Then he smiled. For a moment he looked like himself.
"You're here," he said. "Your mother will be home soon."
Mara stopped mid-step. "Dad. Mom's been gone for a long time."
He blinked, confused for a beat, then nodded as though the correction had clicked into place. She had learned to accept these slips without letting the disappointment reach her face. The disease took him piece by piece, and she had become practiced at pretending each missing fragment weighed nothing at all.
"Of course. Mara." He glanced down at the book. "I must have drifted."
She moved through the room with the practiced grace of someone who knew every misplaced bottle and forgotten detail. She adjusted a half-open drawer, straightened his blanket, counted the pills in his weekly organizer. Routine gave her something to hold onto when emotion threatened to overwhelm.
On his dresser sat the old science fair photo again. He must have placed it there recently. Eleven-year-old Mara beamed beside a lopsided solar system model, her father kneeling beside her with chalk dust still on his sleeves from the lecture he had rushed away from to make it in time. Behind it, half hidden, was a photograph of Robert and Richard Vale outside Vale Biotech's first leased laboratory, younger men squinting into the sun beneath a temporary company sign. He had always rearranged his life so she never felt second to his students, the company, or anything else.
He watched her quietly. "You always took it better than I did," he said.
"Took what?" she asked, though she knew he wouldn't remember the origin of the phrase.
His expression tightened. "I don't know. I had it a second ago."
She knelt beside him. "How are you feeling today?"
"Scattered. I start a thought and lose it halfway through. Then I can't remember what I was trying to say."
She took his hand, feeling the tremor in his fingers. "I know." She squeezed his hand. "I'm sorry."
His gaze sharpened. "If my memories go, what is left of me?"
Mara froze. Every clinical answer felt evasive, and she had nothing comforting that was true.
"I... I don't know," she whispered. "You'll still have me."
He nodded gently, a loving smile spreading across his face.
The moment broke. His attention returned to the book in his lap. She watched him struggle to track the words on the page, a task he once performed with the ease of breathing. He slipped his finger along the margin to keep his place. His handwriting filled the edges, the annotations of a mind that used to move with precision and curiosity.
Now those notes only reminded her of what he was losing.
She stood and smoothed the front of her coat.
"I have to get to the lab," she said.
He nodded again, but she wasn't sure he understood.
As she reached the doorway, he spoke in a soft, fragile voice.
"Please. Don't let me disappear."
The words followed her into the hallway. She kept walking before the fear could reach her face.
She stepped into the bright morning, jaw tight, breathing steady. Vale Biotech was running out of time.
Her father had even less.
