Denise (Lisa Bonet) mistakenly believes that her handsome new geology professor Byron Walcott (David Alan Grier) has fallen in love with her. When dorm director Stevie (Loretta Devine in her final series appearance) confronts the bemused Walcott and accuses him of leading Denise on, Dwayne (Kadeem Hardison) overhears the conversation and concludes that Stevie's interest in the Professor is far more than academic. Meanwhile, Maggie (Marisa Tomei) wages war against the notion of "personal space", ending up way too close for comfort to everyone around her. ~ Hal Erickson, Rovi
