He was a covert operative who worked with Michael during his spy days in Serbia and Russia until he became disillusioned with his government and even tried to persuade Michael that it was their government that burned him. By nature, Larry is outwardly friendly and cordial, but is really extremely violent, hot-tempered, ruthless and sociopathic. During the crazy times in Serbia they were serving in, Larry seemed somewhat sane in comparison. Larry eventually saw their government superiors as restrictive and even traitorous towards their own operatives so he decided to enter "retirement" by walking into an oil refinery right before it exploded as witnessed by 15 others. Presumed dead, Larry became a contract killer. After several terrorist attacks were pinned on Michael, Larry came to believe that Michael had finally adopted his philosophy on life and business.
