What is a key feature of the Whisperer’s control methods?

The key feature of the Whisperer’s control methods lies in the use of employing mind control techniques. This reflects how the Whisperer manipulates the thoughts and behaviors of individuals, particularly children, to achieve his aims. Through persuasive and psychological tactics, along with various subtle forms of influence, he gains control over their minds, leading them to act in ways that align with his objectives. This psychological manipulation is central to his strategy, distinguishing it from more straightforward methods such as physical barriers or technology-based isolation.

While creating safe environments, isolating individuals through technology, and utilizing physical barriers may be relevant strategies employed by characters in different contexts, they do not capture the essence of the Whisperer's specific approach. The focus on mind control underscores the nature of his influence, which is less about physical constraints and more about mental domination, making it a defining characteristic of his control methods.
