Jack Johnson was born in the town of Troy, South Carolina. 
The calm wilderness of southern South Carolina North of Georgia was home. 
He spent a stupid amount of his time before the outbreak as a drunkard logger. Hunting for logs. 
He grew up in with alot of wildlife he had to help fend off, lest he get a beating from his parents, fending off bears, cougars(women as well), other hungry critters, and many a wolf.
Jack was abused as a child by their drug addict parents. 
Jack later became an extreme drunkard, and did many drugs. 
By 25 he was completely focused on when he would get his next drink. He had developed Schizophrenia and multiple personality disorder as a result of a terrible head injury sustained while drinking.
He and his cousin John Jackson found themselves in Norway for a job opportunity as loggers seeing as one of them was already well experienced.
Jack was in Norway when the virus hit. 
Luckily he was in the wilderness away from large populations when it did.
he is now living in the forests nearby of Nyheim, surviving but never thriving..... don't let him see you.............
