Despite attempts to create distance, Derek aggressively pushes the narrator to keep up, which adds to their discomfort. The presence of Simon, who is closely following, adds to the narrator's feeling of being trapped as they navigate the situation together.

However, Simon's actions prevent this, as he physically guides the narrator back into the inseparable duo with Derek. This interaction highlights the tension and challenges within their relationships, setting the stage for deeper emotional conflicts.
