Olek first appears in the pilot episode, when Lucas hood first arrives to New York to visit Job, and tried to kill Hood. He fails, but discharges many bullets in the busy Manhattan street, but somehow no police officers arrive or try to stop or arrest him. He does shoot several bystanders and causes a tour bus to flip over, causing injuries and possibly civilian casualties. (Though unclear in the series)
He works for Mr. Rabbit and appears to hold a personal grudge against Lucas Hood.
