The protagonist reflects on Franz's character, recognizing that while he possesses external strength, he lacks the strength to assert himself in personal relationships. This inner weakness stems from his inherent goodness, preventing him from exerting control over others, unlike Tomas. Franz's inability to give commands, such as asking Sabina to walk on a mirror, highlights a fundamental difference in their approaches to love and intimacy.

Furthermore, the text suggests a complex interplay between love and violence, positing that genuine physical love cannot exist without an element of force. This notion challenges traditional views on the nature of affection, emphasizing that deeper connections may involve a struggle or exertion of power. Kundera's exploration of these themes reflects on the paradoxes within human relationships and the emotional ramifications of strength and weakness.
