Like her brother Tad, Tricia has been raised to be a perfect little angel. Her interests include current events, weather forecasting, and natural foods. She enjoys dancing to an old scratched record that tells of the virtues of self-esteem.  Usually Quinn is he babysitter, but on one particular occasion Daria gets the job.

Her first impression of Daria as a babysitter is somewhat negative, but Tricia warms to her after a while, mostly because she likes Daria's unique interpretations of classic fairy tales. By the end of one evening with Daria as her sitter, Tricia is embracing the ways of the cynic, much to her parents' horror.
