Chapter 7 - THE REPORT THAT EXPLAINED THE POISON, AND THE QUESTION THAT BROKE HIM

The engineering team later identified a defect involving the renovated air-handling system and the exhaust ventilation serving gas-fired equipment.
Under certain operating conditions, the altered airflow allowed combustion gases to enter a connected return-air pathway.
That pathway carried contaminated air toward the upper bedroom wing.
The fragrance dispenser explained the artificial floral smell I had noticed, but it had not produced the carbon monoxide.
The danger came from the combustion equipment and the defective airflow arrangement.
Because the problem varied with operating conditions, the twins' exposure could also have varied from day to day.
A full reconstruction of the previous eighteen months would not be possible.
Still, the findings established that the estate had contained an unsafe source of carbon monoxide near the spaces the boys occupied.
Vincent listened to the explanation in silence.
Then he asked whether the original inspection warning should have prevented the system from being used.
The engineer answered without hesitation.
"The recommendation should have been investigated before the equipment was accepted."
Vincent closed his eyes.
I knew he was hearing more than a technical assessment.
He was hearing every night he'd carried a sleepy child upstairs.
Every morning he'd encouraged them to try walking farther.
Every moment he'd told them that the next specialist might finally help.
That evening, Lucas and Leo remained in the hospital for further evaluation.
Lucas was more alert than he had been that morning.
He asked for chicken soup, complained that the hospital television had terrible cartoons, and wanted to know whether his toy racing cars were safe.
Vincent smiled through tears.
"They're fine, buddy."
"Can you bring the red one?"
"Anything you want."
Leo was quieter.
He had experienced more difficulty with concentration and balance during the medical examination.
When I entered his room, he was staring at his hands.
"Claire?"
"Yes, sweetheart?"
"Did the house make us sick?"
I pulled a chair beside him.
"The doctors found something dangerous in the air, and they're checking how it affected you."
He thought about that.
"Will Daddy be mad?"
"He's upset about what happened."
Leo's eyes filled.
"At us?"
My heart broke.
"Never at you."
He looked toward the door.
"Sometimes we told him our heads hurt when the air started blowing."
I held my breath.
"What did he say?"
"He said the doctors were trying to help."
Leo rubbed his eyes.
"I think he thought we were scared."
"Maybe he didn't understand what was happening."
"Will he believe us now?"
I took his hand.
"He believes you."
Later, I found Vincent standing alone outside the boys' rooms.
He had heard the last part of our conversation.
"He asked whether I believed him."
His voice was barely audible.
"I heard."
Vincent leaned against the wall.
"My sons were trying to tell me what was happening in the only words they had."
He pressed a hand over his eyes.
"And I kept telling them to be brave."
I stood beside him.
"Then tell them you're listening now."
He entered Leo's room a few minutes later.
I remained near the doorway while Vincent sat carefully on the bed.
"Leo, I need to say something."
The little boy looked up.
"I should have listened more carefully when you told me how you felt."
Leo watched him.
"I thought doctors knew everything."
"They know a lot, but they don't know everything."
Vincent took his son's hand.
"And neither do I."
Leo leaned against his father.
"Are we going home?"
"Not to that house until it's safe."
"What about Mommy's flowers?"
Vincent swallowed.
"We can have her flowers wherever we live."
I turned away to give them privacy.
For several precious minutes, the room was peaceful.
Then a nurse approached and asked Vincent to meet with the pediatric specialist.
I followed him into a consultation room.
The physician had reviewed the boys' initial examinations and was arranging further neurological assessment.
She explained that their symptoms and exposure history were concerning, but their individual recoveries might not follow the same course.
Vincent leaned forward.
"Are they both getting better?"
"Lucas is showing encouraging improvement in his alertness and appetite."
"And Leo?"
The physician hesitated.
"Leo is still having significant difficulty with balance and weakness."
Vincent's face tightened.
"What does that mean?"
"We need additional assessment and continued monitoring."
"Could it be permanent?"
"We can't determine that today."
He looked toward the corridor.
"He's seven years old."
"I know."
The doctor took a breath.
"I also need to prepare you for the possibility that Leo may require a much longer recovery and rehabilitation process than his brother."
Vincent gripped the edge of the table.
At that moment, the door opened.
A nurse stood there, her expression serious.
"Mr. Moretti, Leo tried to get out of bed, and he fell before we could reach him."
Vincent pushed his chair back.
"Is he hurt?"
"He's being examined now."
We hurried into the hallway.
From inside Leo's room came a small, terrified voice.
"Daddy, I can't make my legs hold me."
Vincent stopped in the doorway.
Leo was crying as the nurses helped him safely back onto the bed.

Then the child looked directly at his father and asked the question that shattered what little composure Vincent had left.
"Daddy, am I ever going to be able to run with Lucas again?"
