Lisa, supportive of Rafi's relationship with a younger man, discovers the connection and finds herself not only faced with the ethical and moral dilemma of counseling David's girlfriend, but also the reality that she feels differently about the relationship now that she knows her son is involved. Lisa consults her own therapist, and they decide that it is in the best interest of her patient Rafi for Lisa to continue treatment, as long as the relationship remains the "fling" it appears to be. However, Lisa soon realizes that the relationship is serious, and tells Rafi that she is David's mother. Feeling embarrassed and betrayed, Rafi ends her treatment with Lisa.

A few days later, Rafi discovers that David had slept with Sue, and David and Rafi fight. After sulking for some time, David goes to seek Lisa's help as both his mother and as a therapist.
