What does Enzo notice about Zoë?

Enzo's observations about Zoë reveal the emotional complexities of her situation. When he notices that she feels lonely without living with Denny, it highlights the bond that they share as a family unit. Zoë's sense of loneliness reflects how the changes in their living situation affect her emotionally. This insight also underscores Enzo's role as a companion and protector, as he is attuned to her feelings and experiences.

The other choices don't accurately capture the depth of Enzo's observations of Zoë's emotional state. While she may have moments of excitement or be in the process of making new friends, the primary feeling of loneliness stands out as significant in the context of her separation from Denny. Additionally, while acting out could be a response to her feelings, the direct recognition of her loneliness carries more weight in illustrating her internal struggle during this transitional phase in her life.
