And I wouldn’t call the female rabbi character a hero, necessarily. She appears for about 10 seconds, in the operating room, in full scrubs including cap and mask. She contributes nothing to the issue of animal heart transplants and Jewish law - she just sings a couple of lines from the mishaberach for the sick just before the patient goes under. I would bet that 95% of viewers had no idea what was going on (this happened straight from a cut with no explanation or introduction) or that this masked person was supposed to be a rabbi.
