*Possible Spoilers*
A man and woman are presumably fully nude. We only ever see them from the waist up, thus the man's bare chest and woman's bare breasts are seen. The woman strips off her clothes to join the man, who is already unclothed, in bed. Man climbs on top of her covered by sheet. Sex is implied.
A woman, who we can safely assume is a prostitute, receives a client during the day. She brings him to her room, commenting that he looks familiar and has likely been with her before. Nothing more is seen or heard.
