Emotional Marla imperils a promotion; rattled Hanson tends to a 4-year-old niece; conflicted Aisha (Tamyra Gray), recast in the school musical, confronts her jealous boyfriend.

Tensions surface over Ronnie's new post; Aisha's participation in the school musical and her relationship with J.T.; Harvey's required recertification; and Danny's care for his niece.

Aisha (Gray) is shocked when her father, a one-time famous musician but now an alcoholic, makes a surprise visit to Winslow High. He is seriously ill and leaves Aisha a tattered song manuscript. She puts words to the melody, which becomes her rendition of ""Dance With My Father"" (Luther Vandross' biographical song to be released in June). Meanwhile, motherhood troubles Marcie, who's taking a parental-training course, and fears for his niece's welfare preoccupy Danny, whose sister is still using drugs.

Hanson, looking for a way to increase his chances in adopting his niece, makes a sudden proposal to Claire (Missy Yager). Meanwhile, Guber challenges a student (rap star GQ guest stars) who wants to use rap music to show why Shakespeare ""sucks""; and Marilyn doesn't trust a record producer (hip-hop star/actor Method Man guest stars) who's pushing to sign Aisha to a recording deal. Also of note for this episode, the band Lifehouse (""Hanging by a Moment"") will perform at Doyle's Bar.

Henry gives bad advice to a brainiac student who wants to become an artist; Marla has a miscarriage; Rainy is thrown out of her foster home.
