You are a counsellor and approved supervisor working in your own private practice. One of your supervisees, Mary, who has been with you for over twelve months, has told you that her sister is going through a lengthy and difficult relationship breakdown. Mary has previously suggested to her sister that she seek counselling but her sister has rejected the idea outright. Recently, however, when they met for coffee, her sister said that she would attend counselling but only if it could be with you, as she felt that she would be comfortable with you from what Mary had told her. Mary intends to continue to work with you as her supervisor.

What would you do in this situation; what issues does it raise?
