Aunt Bernice

From DariaWiki

Aunt Bernice (Lane?) is the aunt of Jane and Trent, living in Middlebury. She's known for her monstrously ugly hats... which Trent blithely mentioned on a flight to the Lane family reunion in "The Teachings of Don Jake", unaware Bernice got on the same plane to it that they did.

Bernice got her revenge by seeing Jane and Trent needed a ride, slooooowing her rental car to them.... and then speeding off. However, the Lawndale two turned the tables on her by the end of the episode, by stealing her rental car to the airport.
