It’s time for the Johnson kids’ first school dance, but before Bow can dance the night away, she’ll have to consider the social impact of her date choice. Johan finds an outfit for the dance and discovers his love of fashion, while Santamonica spends some time with Harrison.

In the wake of the Challenger tragedy, Rainbow and her family handle their grief in different ways. Denise realizes that life is too short, so she vows to right all the wrongs she’s done in her life (and she’s done a lot of bad).

Rainbow’s friend Rebecca gets mono (“the kissing disease”), and after helping her out, she becomes interested in the medical field. Alicia fibs to Paul about getting a flu shot, and when Denise gets sick, their distrust of the medical community comes to light. Meanwhile, Johan and Santamonica go to live with Harrison while Denise is sick and start to enjoy his lavish lifestyle.

Paul surprises the family by inviting one of his students to live with them, and Paul and Alicia compete to be his mentor. Meanwhile, Rainbow has a crush on their new house guest.
