However, if we had to pick one character who might be considered the "lead" in terms of driving the plot, it would be Steve, the young man who initially suggests an alien presence on the street. His skepticism and accusations, although ultimately unfounded, set in motion the chain of events that leads to the downfall of the community.
While Steve is the catalyst, it's important to remember that every character, from the nervous Charlie to the seemingly calm Tommy, contributes to the escalating tensions and distrust. The play's focus is on the collective behavior of the community, and the role of each individual in that process.
