Before Campbell can call Julia to the stand, Sara butts in and calls someone else: a child psychiatrist named Dr. Beata Neaux.
Dr. Neaux testifies that donating a kidney would be good for Anna; she would consider herself a "superhero" (9.2.21).
Campbell cross-examines (no nudge-nudge italics) Dr. Neaux, saying that if Anna gives a kidney and Kate still dies, wouldn't that cause "significant psychological trauma?" (9.2.31).
Dr. Neaux continues, saying that Sara also benefits psychologically from keeping Kate alive.
So Campbell wonders, since Sara is just as emotionally invested as Anna is "why is [Sara] any more capable of making this choice than Anna?" (9.2.45).
The judge bangs his gavel (he must have been feeling left out) and Campbell concludes, "Parents need to be parents […] but something that isn't good enough" (9.2.46).
