Dr Patterson is the attending physician who took responsibility for Robert Knight following his collapse. Hair the colour of iron filings, posture cutting a straight line through the cluttered corridor, voice clipped but not unkind, calm in the particular way of doctors who have learned to deliver bad news without rehearsing it. She arrives at the bedside in Chapter Forty-Seven: How to Save a Life, runs every available test, and returns with a verdict that is medically accurate and entirely wrong about what has actually happened.
Her workup is thorough: penlight to the pupils — no reaction — tongue depressor against the gumline, pulse, monitor, EEG, MRI, lumbar puncture, full blood panel. The results give her nothing. No neurological cause. No infection. Nothing scanning could find. Ben’s line, delivered to the room before she returns, is You can’t scan for what this is; he is not addressing her, but he might as well be. When Patterson does come back at six o’clock with her hair flattened and shadows settled deep beneath her eyes, she lifts Robert’s hand and lets it drop. Dead weight. She straightens. She says what she has to say. There is no neurological cause we can find. Which leaves us with a functional explanation. Stress-induced. I have seen it in adolescents before — the mind does this, sometimes, when it cannot process what has happened to it. It is not malingering. Nor is it necessarily permanent.
The diagnosis is the best one available to her. It is also wrong. It rests on a model of what minds and bodies can and cannot do that has no provision for what is in fact happening to Robert. Patterson is not at fault for this. The model is the model. She is delivering, with care, the closest thing the model has to an answer. It could be weeks. It could be longer. She does not say it could be never. She does not say it because she does not believe it. The Knights, she registers without naming the registration, do not look as if they are hearing it for the first time.
