Plot: Jeffrey runs afoul of the trustees when a grieving husband has second thoughts after allowing him to test an artificial heart on the body of the man's newly deceased wife; Alan comes to the rescue when a patient's HMO refuses to cover Aaron's operating on her very complicated and potentially fatal brain tumor; Jeffrey visits his wife Laurie, a straitjacketed patient in a mental hospital who apologizes for drowning their son Joey; Arthur's refusal to remove his wagging finger from Jeffrey's face during an argument leaves him with a bitten digit, and enables Jeffrey to diagnose the curable medical condition that's causing Arthur's resting tremor.
