Sister, Sister - Get your storyline straight...
This slip-up occurs in the season one episode Operation Deja View, when Tia and Tamera are in the hospital for their appendicitis, the doctor remarks that the twins' medical reccords are at this hospital because this was where they were supposedly born. But, in future episodes, such as You Are So Beautiful and Father's Day, it's said the girls were born in Sarasota FL. This was a major slip-up because a storyline formed into the series about the girls' biological parents.
