Sister, Sister

The twins discover each other in a clothing store, but learn that they may be separated again when Lisa confesses that she was fired weeks ago and has found a new job in St. Louis. The twins conspire to run away together to Minneapolis-St. Paul, the ""twin cities,"" but are discovered by Ray and Lisa, who agree to share Ray's house together despite their strong mutual dislike.

Having found a date, Tamera sidesteps a pact with Tia in which they agreed to forego the school dance unless they both had dates.

Tia and Tamera host a slumber party, while Lisa puts her hopes of romance to rest after catching her two-timing beau in the act.

To impress her dad with better grades, Tamera persuades honor student Tia to take a history test in her place.

Meanwhile, Lisa convinces Ray to take Little Ray to the vet and Ray doesn't want to pay for the bill.

When Tia's anxieties about a prominent pimple come to a head, she asks Tamera to go out on a date in her place.
