Little White Lies

S18, E85: Gina is in Okaro's bad books for ruining the operation at the department store. Gemma sleeps with Melanie from Marilyn Costello's club where she is working undercover, unaware that she is the insider at the store. Gilmore steps in when the store wants Kerry to pay for the ruined wedding dress, and Kerry finally breaks down over Cass' death. Under the pretence of helping her escape the country, Gemma brings Melanie into Sun Hill, where Melanie makes a statement about Marilyn. The police raid the club, but SO19 are forced to take action when Marilyn takes her son Tommy hostage at gunpoint. Cathy assumes the worst when she is stabbed in the arm with a hypodermic needle. An HIV test proves negative, but she tells a sympathetic Brandon a different story.
