As Dwayne (Kadeem Hardison) prepares to make his valedictory speech at Hillman's graduation ceremony, he must also cope with the likelihood that Whitley (Jasmine Guy) will be leaving him to accept a job in New York. Meanwhile, Ron tries to keep his dad from finding out that he isn't eligible to graduate by purchasing a cap and gown and going through the motions of attending the ceremony--a clever ruse that works for, oh, approximately one whole day. This "cliffhanger" episode brings the fourth season of A Different World to a close. ~ Hal Erickson, Rovi
