Her no-nonsense, all-business demeanor and arrogant and stand-offish attitude earn her the dislike of the other staff. Frasier makes an advance towards her in a moment of anger-induced passion, similar to a scene in an episode with Kate Costas, with Frasier even using some of the same insults and quoting the famous line by Sam Malone to Diane Chambers in Cheers "Are you as turned on as I am?", which results in the entire station being forced to attend a sexual harassment seminar until Julia promises not to sue Frasier or the station, after which the entire staff leave the seminar.
When Frasier discovers that his accountant and former Oxford classmate, Avery (John Hannah), is cheating on his wife with Julia, he confronts Avery, unaware that Julia is hiding in a closet, overhearing the entire conversation. Julia's attitude towards Frasier begins to soften after this display of chivalry on his part, and she uses her connections to have Ben, a British street musician (Elvis Costello) whom Frasier and Niles find annoying, then playing a regular gig at Café Nervosa, offered a full-time job elsewhere.
She and Frasier have a brief romantic encounter, although her boorish and coarse behavior towards Martin, Niles, and Daphne ultimately persuades Frasier to break off their relationship.
