She turned another page.
Jack’s name appeared again.
“What did you do there?”
“Systems design.
Hardware integration.
Whatever needed doing.”
“Your Nexus file says ‘various employment.'”
“That’s what I wrote.”
“Why?”
Jack leaned back against the bench.
“Because when I applied for the cleaning job, nobody was hiring me to design systems.
They were hiring someone to clean bathrooms and empty bins.”
Catherine studied him.
“You worked on the original architecture.”
“Parts of it.”
“Parts?”
He pointed toward the document she was holding.
“The fault-tolerance layer.
Thermal monitoring.
Some of the physical routing logic.
Other engineers did the rest.
It wasn’t a one-man miracle.”
That answer sounded like an engineer’s answer, not a boast.
Catherine looked around the garage again.
What she had first interpreted as a secret laboratory now looked more like the remains of a career carefully boxed and stacked around domestic life.
Old boards labeled in marker.
Test meters patched with tape.
Technical manuals.
A desk squeezed between a lawn mower and shelves of canned food.
“How does someone who designed systems end up cleaning the building that uses them?”
For the first time, Jack looked tired rather than defensive.
“Slowly.”
He told her the smaller company had collapsed after funding disappeared.
Its assets were sold.
Employees scattered.
Jack had no degree, only years of practical work and recommendations from people who themselves soon lost jobs or moved away.
He found contract work, then temporary work.
At the same time, his marriage ended and he became the primary parent.
Reliable hours mattered more than impressive titles.
His mother Elaine helped when she could, but Jack needed health benefits, predictable shifts, and a job he could keep while raising his child.
Nexus had an opening on the night cleaning crew.
So he took it.
“For four years?” Catherine asked.
“For four years.”
“And you never told anyone here what you used to do?”
Jack met her eyes.
“Would it have mattered?”
Catherine almost answered immediately.
Then she remembered Marcus looking at Jack’s thin personnel folder that morning.
Quiet guy.
Reliable.
That’s what we’ve got.
She said nothing.
Jack turned toward the workbench and picked up the failed sensor with tweezers.
“About seven weeks ago, I noticed the cooling cycle in one of the R&D racks was pulsing wrong.
You can hear it if you know the old hardware.”
