Richard Dean Anderson (Carter) and Linda Blair (Muffy) would reunite 8 years later in the MacGyver episode "Jenny's Chance" (1990)
(Good #3) -- When Nurse Charlene administers the blood pressure test to Gopher, there's a thermometer in his closed mouth. As she chats with Isaac and pumps away absentmindedly, she cuts the circulation in Gopher's right arm, which causes him to exhibit quiet signs of distress. During one of the short close-ups on his face, Gopher grimaces with an open mouth, without any thermometer in sight; one second later, the thermometer is back into his mouth.
Coleen must have had a strong death wish: when Isaac enters her cabin, not only has she got dozens upon dozens of lit candles, all her lamps are turned on and flimsy, synthetic scarves have been placed on all the shades. (Their see-throughness gives away that they're either polyester or nylon.) Double fire hazard here: it is very dangerous to have lit candles on a boat, due to high seas easily toppling them over. This, besides being overweight and constantly stuffing herself with pastries.
