10 Things I Hate About You

Walter Stratford, an obstetrician, is overly concerned about teenage pregnancy and wants to protect his daughters. He imposes a rule that neither Bianca nor Kat can date until the other does, thinking this would prevent them from getting into trouble. This rule becomes the central obstacle that drives much of the plot's complications.

The rule is introduced early when Cameron learns about it from Michael, immediately setting up the story's main conflict.

Patrick pulls away because he realizes Kat is vulnerable and intoxicated from drinking too much at the party. He doesn't want to take advantage of her emotional state and decides to wait until she's in a clearer frame of mind. This shows his genuine respect for her, though his timing is unfortunately poor and hurts Kat's feelings.

Earlier at the party, Kat feels vulnerable after seeing Bianca with Joey, leading her to drink excessively.

Joey wants to date Bianca, but he can't because of Walter's dating rule. Cameron and Michael convince Joey that if Patrick dates Kat first, Bianca will be allowed to date, clearing the path for Joey to pursue Bianca. Joey agrees to pay Patrick because he believes it serves his own interests, not realizing the scheme will backfire.

The plan is established early when Cameron explains the dating restriction and proposes using Patrick as a means to an end.

Kat tells Bianca about her past encounter with Joey because she wants to protect her sister from making the same mistake she did. Kat had a negative experience with Joey and regrets it, so she shares this information hoping to prevent Bianca from being hurt by him. This revelation creates tension between the sisters initially, but ultimately helps Bianca see Joey's true nature.

This confrontation happens when Joey tries to manipulate the prom situation, pushing the sisters apart.

Patrick's serenade matters because it represents a genuine, grand romantic gesture that breaks through Kat's defenses. Despite being initially hired to date her, Patrick has developed real feelings for Kat. The elaborate performance with the marching band demonstrates his commitment and sincerity, finally convincing Kat that his intentions are genuine despite her suspicions.

Kat's feelings become complicated when Patrick insists she attend prom with him, making her doubt his motives.

Kat becomes suspicious because she knows Patrick was originally hired to date her, which makes her question whether his feelings are genuine or just part of the scheme. When he insists she attend prom with him, she wonders if he's still being paid or manipulated by Joey. Her suspicions reflect her protective nature and fear of being vulnerable again after being hurt.

This doubt emerges from the earlier revelation that Joey paid Patrick, making Kat question the authenticity of their relationship.

Walter changes his mind about Kat attending Sarah Lawrence after witnessing her maturity and independence during the prom events. When Kat stands up to Joey's aggression and defends her friends, Walter sees that his daughter has grown into a responsible young adult capable of making good decisions. This moment of confidence in Kat reflects his growth as a father.

Earlier, Walter wanted Kat to attend the nearby University of Washington to keep her close to home.

Kat's poem '10 Things I Hate About You' is a Shakespearean-style sonnet that reveals her lingering feelings for Patrick despite her initial tough exterior. The poem lists the things she hates about him, but underneath the criticism is her deep affection. It's her way of publicly expressing vulnerability and admitting she loves him, even though she's been difficult and defensive throughout their relationship.

The poem is presented in class as a creative assignment where students interpret Shakespeare's Sonnet 141.

Patrick buys Kat the Fender Stratocaster using the money Joey originally paid him to date Kat. Rather than spending it on himself, he uses it to gift her something meaningful that connects to her dream of forming a band. This gesture shows his genuine affection and that he invested in their relationship rather than just treating it as a job.

Joey paid Patrick to take Kat out as part of the original scheme to get to Bianca.

Bianca chooses Cameron because she realizes he genuinely cares about her, while Joey only wanted her for superficial reasons. Through spending time with both boys, Bianca sees Cameron's sincerity and kindness, contrasted with Joey's manipulative and selfish behavior. At prom, when Joey's true colors are fully revealed, Bianca makes the clear choice to be with Cameron.

Earlier, Bianca notices Cameron's genuine affection and rewards it with an unexpected kiss.
