Long before the outbreak Jim was kinda lost in life between lack of confidence and family struggles (alcoholic american mother with suicidal tendencies and absent french father made his life as a young man more complicated then expected as he had to manage the family's house and take care of his mother's problems).
He's a social guy but he knows only a few are really worth it with all those fake masks people were wearing and living carefree.
He was jumping from shitty job to shitty job (security agent , salesman, Mc Donald employee) until he found out what he was made for, designing websites, but, he did not found any company to stay in, so Jim decided to be a freelance web designer (it was also some sort of therapy for him to finally be the one in charge and something he could possibly be proud of). Two month before the outbreak he decided to leave France (were he was born) since the taxes and charges for a french company were really hard to handle as a starting freelancer. He heard about Chernarus being one of those countries where life is cheaper and from where he could work for anybody in the world making good money.
When the outbreak started he decided to not follow the masses toward any extraction sites as he never really liked doing things the same way as everyone for not having the same point of reference everyone had : good family, fake friends and so on.
All the events he witnessed after the outbreak, the bombings, people dying everywhere when running around like headless chickens and the ambiant panic appeared to Jim as just another shit hitting his already dirty fan. "So be it" he said to himself when going toward the nearest forest "Maybe something good could happen after all this panic settles down, something less fake".
Jim proceeded to live the hunter life, real and simple he thought ... until he met a rat ...
