Later that evening, Paul answers an on-line ad for an escort named Bianca. They agree to meet at a seedy motel, but Paul brings a knife with him. Just in case.
Bianca welcomes Paul into her room and tells him to undress as she departs to the bathroom. As Paul lies in bed awaiting Bianca's return, he hears voices. Panicked, Paul quickly dresses, arms himself with the knife, and tries to leave. Joel, Bianca's boyfriend and pimp, stops him. A fight ensues, and Joel is dead. In the fracas, the motel manager bangs on the door to inquire about the noise. Bianca and Paul decide to cover up Joe's death rather than call the police and letting the whole world know what they were doing.
