A Different World

During her first few days at Hillman College, Denise Huxtable finds herself at odds with her new roommate, Jaleesa, a 26-year-old freshman with a mysterious past.

As the school year begins, Dwayne faces the prospect of taking a calculus class from Col. Taylor, a tough professor nicknamed ""Dr. War."" He fears that Col. Taylor could expose his academic success as a fluke and destroy his dreams of becoming an engineer, so he asks Walter to help him get into another section. Walter believes that Dwayne could thrive under Col. Taylor's tutelage, and asks the professor to talk to him. Col. Taylor manages to change Dwayne's mind and convince him to enroll in his class. Whitley meets new roommate Kim Reese, a headstrong freshman who plans to become a doctor. Whitley hopes to intimidate Kim and drive her to another room, but finds it impossible to break her. Jaleesa's cheerful freshman roommate, Freddie Brooks, develops a massive crush on Dwayne.

Dwayne and Whitley run into each other on a flight back to school. Whitley finds that Dwayne has changed over the summer, as he is dressed in an expensive suit and seems to have matured during his successful internship at Kinishewa. Dwayne comforts Whitley when the plane experiences turbulence. Whitley kisses Dwayne in front of her entire dorm, prompting much teasing from her friends. Each insists that they are only friends. Whitley goes to Dwayne's apartment to see him, but is turned off when she finds him dancing like an idiot at a party. The residents of Gilbert Hall struggle to adjust to the fact that the dorm is now coed. Walter is the resident director, with Jaleesa as resident assistant.

Whitley thrills her friends by announcing that she has finally decided that Dwayne is the right man for her. Although she answered his love letters during the summer, she chose not to send her replies because she wanted to leave him begging for more. When she goes to Dwayne's apartment to share her feelings, she discovers that he met someone during his summer in Japan. He introduces her to girlfriend Kinu, a beautiful Japanese American who attends nearby Avery College. In addition to her emotional turmoil, Whitley does not have a place to live because she lost her apartment by failing to pay the security deposit. Jaleesa reluctantly allows her to temporarily stay at her apartment (across the hall from Dwayne's). Whitley vows that she will not screw up if she gets another chance with Dwayne. Col. Taylor's son Terrence enrolls at Hillman. His overzealous behavior around women earns him the nickname ""Pee Wee Hormone.""

Dwayne and Whitley prepare for the coming school year at Hillman. He will teach classes, and she will serve as director of a new dormitory. She accepted his proposal and only kept the New York job for the summer. Dwayne asks Ron to pick up Whitley's engagement ring while he is stuck in a meeting. Ron somehow does not realize that the 2.5 carat ring the jeweler gives him is not the one that Dwayne purchased. Street-smart freshman Lena James tries to find housing after the computer fails to give her a room. She manipulates Whitley into letting her stay in her extra bedroom. Col. Taylor and Jaleesa shock everyone by revealing that they eloped. Terrence has trouble getting used to the idea of having a stepmother.

Whitley and Dwayne recall their fateful honeymoon in L.A.
