Jack along with his sister Liz have been on their own since they were kids. With no family other than each other, they lived on the streets and survived by any means they could find. They even broke the law to feed, clothe and shelter themselves. But only took from the rich in a "Robin Hood-like manner, helping themselves as well as others less fortunate. Jack likes to do things his way and any authority is a threat to his survival. He is very loyal to his sister and his friends. He is always someone you can count on when he commits to something. He is playful and has a great sense of humor. He is a born leader though hates to take on that role. He doesn't like to workout, eats junk food and doesn't like to study.
