Skywalker, who is officially assigned to protect Amidala from an assassination plot, begins crossing professional and personal boundaries as soon as he’s alone with her. While Amidala is packing her bags for a long trip with her state-appointed protector, Skywalker starts making inappropriate advances. She flat out tells him, “Don’t look at me like that,” because “it makes me feel uncomfortable.” He simultaneously offers a facetious apology and undermines her own position of authority over him.
Skywalker has already overstepped his boundaries in a professional setting. She calls him out on it, and it should be the end of the story. But he insists on harassing Amidala for the duration of the film, making her feel, at turns, uncomfortable and unsafe.
