But nobody could make the grief disappear.
Three years after Sophie died, Doc had two words tattooed across his knuckles.
GO ON.
They were the words he remembered hearing from her whenever he hesitated during one of their imaginary adventures.
"Go on, Daddy."
She would say it when he paused a story.
"Go on."
She would say it when he stopped pushing her swing.
"Go on."
She would say it when he pretended to be too tired to chase her through the backyard.
The tattoo wasn't a command to forget.
It was a reminder that continuing to live wasn't the same as leaving her behind.
Doc had spent years trying to believe that.
Some days he succeeded.
Some days he didn't.
But on the evening he met Ellie Forrester, the words seemed to have found a new meaning.
He placed the pink ribbon back inside his vest.
Then he looked toward the motorcycle on the lift.
An ordinary passenger seat would never work for Ellie.
Rachel had been clear.
The girl's condition made normal motorcycle riding unsafe, and Doc had no intention of risking her life simply to keep a promise.
He knew what it meant to watch a medical team fight for a child's safety.
He would not pretend that mechanical enthusiasm could replace medical judgment.
But another thought had begun forming.
What if the motorcycle didn't need to be ridden in the ordinary way?
What if there were a carefully engineered way for Ellie to experience being part of the machine without requiring her to balance behind a rider?
What if the experience took place somewhere controlled, with support, supervision, and every necessary approval?
Doc looked at the black Harley.
For the first time in years, an idea made him feel both frightened and hopeful.
He pulled a notebook from the workbench.
At the top of the first page, he wrote one word.
Ellie.
Then he drew a line beneath it.
And he began to sketch.
The next morning, Rachel Forrester was standing in the kitchen preparing Ellie's medication when her phone rang.
The number was unfamiliar.
She considered ignoring it.
Her mornings had become carefully arranged routines, and interruptions made everything more difficult. Ellie had already needed help getting dressed, Mark was preparing to leave for work, and Rachel still had to organize the equipment and supplies required for the day's appointments.
