how are izzy, retty and marion significant to Tess and angel?

Mrs. Crick insinuates that a romance in her household is the cause for the stalled butter churn, while Tess's roommates (Retty Priddle, Marian, and Izz Huett) become jealous that she receives the most attention from Angel, whom all of them adore. The jealousy that her roommates feel leads Tess to a realization that she may have a future with Angel Clare, for she believes that he would want to marry a working woman and not a lady of his own social rank; in fact, Tess represents both social spheres, having the family history of a noble lady and the actual history of a working class girl.
