I'm the first episode, Nicole is overwhelmed with the loss of her husband and she is seen in her bathtub with a glass of wine. She starts crying, and the scene cuts back an forth between her son, and her. Nothing explicit is shown, but she is clearly naked.
There is a scene where a woman gets in bed on top of another woman and they kiss. It is then implied that they are in a romantic relationship. This woman/woman relationship is referred back to at least three times, at regular intervals.
