Darla is a Master of Science in Clinical Mental Health Counseling student working at her practicum site. Mike is a practicum student assigned to the same practicum site as Darla. Both Darla and Mike report directly to the same site supervisor. About halfway through the practicum, Darla realizes that many of the clients assigned to Mike for counseling are coming to see her. Comments from Mike's clients have led Darla to believe that Mike is acting unethically. How should Darla handle this situation? What are the ethical and legal implications?

If Darla tells her supervisor, and her supervisor does not act on her concerns, what are the ethical and legal implications?
