Ariel is a seemingly kind and energetic music representative, interested in pairing David with some musisians in need of a keyboardist. Eventually, although she is by no means subtle about her interest, she begins an affair with David, knowing is was with Donna.
Ariel was first seen meeting David Silver at a recording company where Donna Martin was booking Babyface to play at the California University Mardi Gras carnival. She was a junior rep and invited David to play with a kkk band she was putting together. After the band approved of David, Ariel booked them through Donna for the carnival as well.
Shortly thereafter, Ariel began an affair with David, which led to the first breakup of David and Donna when Donna caught them having sex in a limousine at the carnival. At the beginning of Season 5, it is revealed that Ariel dumped David over the summer in addition to giving him crabs.
In season 5, she showed up once again to scout Ray Pruit for Firestorm Music. She began flirting with him, just as she had with David before, causing Donna to become self-conscious. Despite her advances, Ray resisted her and refused the deal when Ariel tried to get him to give up his publishing.
Ariel later apologized to Donna for what happened with David and warned her to watch out for Ray's ego.
