Born in Scottsmoore, Florida, Jeff had led a troubled life since its beginning. Neither especially smart nor physically strong made him the perfect target for bullies. He developed a resentful feeling against everybody and everything.
At the same time he had to improve his skills in order to survive in a society he was always considering hostile.
He joined the US army and became specialist in demolition and explosives. It came from a creative interest in electronics and communication systems.
Captain Hallen included him in his team, where surprisingly, he felt quite integrated, as nobody bullied him while his skills were mostly appreciated. It developed a strong sense of loyalty to the group where he feels secure and integrated.
He lives in a constant climate of distrust and insecurity against the outer world. Those feelings are well exploited by Captain Hallen, to ensure his blind and absolute loyalty.
