For a writing project I have a scene in a psychiatrist's office. Can anyone give a little insight into how a certain part might play out?
Context: Two fifteen year olds, one male and one female, share a foster home. They attend weekly therapy for certain reasons. The female character is high strung, overbearing, bossy, and thinks she's smarter than everyone around her and she approaches each counseling session as a battle between her and and the therapist. Without going into the details of her actual motivations and beliefs, she's relentlessly domineering with her foster brother which is one of the things being explored in their sessions.
The therapist, who by this point knows the girl fairly well, has begun to grow a bit frustrated with her because she's got an excuse for everything and a reasonable explanation for why she does anything she does. He one day finally loses her cool with her briefly in reference to her foster brother. He says something to the effect of "Good lord, just ease up on the boy, will you?"
He immediately recognizes the unprofessional lapse, and in her eyes the girl has just won a great victory in their battle. However, the girl now feels like she's in the dominant position between the two, and this feeling of superiority makes her more willing to open up and be more honest.
Would the therapist exploit this, using the benefit that came from his lapse in judgement to advance their session now that she's going to be less difficult? Would he have some kind of professional obligation to remove himself from her case, or to take a step back? Something else?
