A 30-year-old man with borderline personality disorder is receiving mentalisation-based therapy. During a session, the therapist briefly glances at the clock. He becomes visibly tense, raises his voice and says, "You cannot wait to get rid of me. You have never cared about me." He remains seated and makes no threats. Which is the most appropriate immediate therapeutic intervention?

B is correct. The clock glance has triggered high affect and a rapid, certain attribution about the therapist's mind, indicating a loss of mentalising. The therapist should acknowledge the emotional intensity while maintaining a curious, not-knowing stance and collaboratively examine the sequence from observable event to interpretation. This promotes recovery of flexible thinking about self and other. A premature transference interpretation (A) risks imposing certainty and increasing arousal. Ending the session (C) is disproportionate because no immediate threat or frame violation requiring termination is described. Validation alone followed by deferral (D) misses an opportunity to restore mentalising within the live therapeutic relationship. Direct cognitive disputation (E) prioritises correcting the belief rather than exploring how the mental-state conclusion arose.
