Final answer:
Juliet may feel vulnerable, embarrassed, or fearful, but also possibly relieved or connected, as Romeo hears her innermost thoughts without any pretense.
Step-by-step explanation:
Juliet experiences a complex mix of emotions upon realizing that Romeo has overheard her innermost thoughts. The texts provided do not directly describe Juliet's feelings in this situation, but using the theme of unexpected eavesdropping and self-revelation in these selected excerpts, one can infer Juliet might feel a combination of vulnerability, embarrassment, and possibly fear due to the intimacy of her exposed thoughts. However, it is also possible that she could feel a sense of relief or connection, seeing that Romeo now knows her true feelings without any pretense.
