Baby discovers that Johnny 's dance partner, Penny Johnson, is pregnant by Robbie Gould, a womanizing waiter who is cheating on Baby 's older sister, Lisa. Baby borrows money from her father to pay for Penny 's illegal abortion without explaining why. Penny eventually accepts the money but identifies another issue. Penny will miss her weekly dance performance if she goes for the abortion, forfeiting Penny 's and Johnny 's salary for the season. Billy suggests that Baby fill in for her. Johnny 's scoffing overcomes Baby 's initial resistance. Billy and Penny insist that Johnny can teach anyone to dance. Johnny teaches Baby the mambo, and the two spend several awkward practice sessions together. Baby gradually improves, and they develop a romantic attraction.
