Jack was born to a Starfleet Security Officer father and mother who
was a botanist. He grew up mostly on Starships going planet-side for
vacations. When he was about 10 years old, his parents had a daughter.
He took the role seriously of protecting her. As he got older, he got
into more than one scrape with boys that wanted to get fresh with his
little sister.
As he finished college, he still had no real direction in life. Some
good investments his family had made had insured they had enough money
to live on comfortably for life. Eventually, he got a job on a freighter
and went to travel the universe, dropping notes home every so often.
When he was 28 years old, he learned that his father had been killed
in the line of duty. His mother and sister were returning to Earth where
they were going to hold a memorial for him. Immediately, Jack went home.
Many people were there for the service, but Jack couldnt stay
long. The pain it evoked in him was something he couldnt take.
With money that his father had set aside for him, he bought his own
small cargo ship and began his own business. Sometimes hauling cargo
and sometimes people, but he felt cargo was easier.
Though he still keeps in touch with his mother and sister, he still
keeps pretty much to himself. He has his dog and his business and doesnt
figure he needs much more.
