Dr. O'Donnell

Dr. O'Donnell arrives as a calm, clinical presence in Paul Spector's orbit — a psychiatrist whose job is to assess and treat rather than judge. Measured and quietly probing, he listens more than he speaks, watching for the gaps between what a patient says and what he actually is.

Richard Coyle plays him with a stillness that suits a show built on watching and being watched — a professional whose composure becomes its own kind of tension. The character works because he never overplays suspicion or sympathy, letting the audience do the unsettling work of deciding which one he actually feels.
