 Kimberly becomes nervous when the hospital s new chief-of-staff, Dr. Calvin Hobbs, issues a psychology evaluation for the employees because she knows about her psychotic tendencies. So, she resorts to hiring two thugs to beat up Matt in order to avoid taking the evaluation since Matt is coordinating the tests. Meanwhile, an unusually pail and emaciated Amanda starts giving everyone a hard time at work. Billy thinks she looks sick and asks Michael to inconspicuously examine her during a formal charity ball. Alison s sister, Meredith, arrives in town for a visit and falls for Billy. Sydney begins participating in Martin s activities, much to Jane s disapproval while at the same time, Sydney gets blamed for a series of incidents at Melrose, starting when Jo s apartment is broken into and all her camera equipment is stolen. Then, Jane s apartment is broken into and her dress designs are ruined. Then, Shooters is broken into and trashed and Jake blames Sydney, despite her watertight alibi. But the real culprit is Rikki who (acting under orders from Martin Abbott) is plotting to turn all of Sydney s friends against her to draw her closer to them.
