Just learned a new word: Lone Wolf. From Wikipedia: As a person, a lone wolf is an individual who prefers solitude , is introverted , or who works alone. In literature, lone wolves are aloof and emotionally unable or unwilling to directly interact with other characters in the story. A stereotypical lone wolf will be dark or serious in personality; they are often taciturn, and will distinguish themselves through their reserved nature. From the media : Teroris yang bertindak sendiri dan tak berafiliasi dengan organisasi internasional.
