Angst? What Angst?: Billy always seems to get his cocky attitude and thirst for adventure back, even after surviving dangerous incidents with sea monsters, sharks, and criminals.
Fair for Its Day: The second episode of the second series has Jack reconnect with an old friend, Sam, who he knew as a man, but has transitioned since he last saw her. Much of how this is handled has not aged well, from Jack's horrified reaction, to the way the rest of the crew speculate (in extensive detail) about Sam's genitals, to implying that trans people are 'in disguise' in the stinger. However, Jack's reaction is framed more as a lack of understanding and a childish difficulty dealing with his friend having changed in such major way, rather than being based in disgust or hatred towards trans people in general. His arc through the episode has him come to understand that she's still the same person he always liked and was friends with, and he becomes very insistent about using the right pronouns. The rest of the crew, inappropriate as they're being, are also merely suggested to be curious, rather than hateful. Multiple characters also state that, ultimately, it's what's inside that matters - which is a far kinder take on transgender people than many other comedic works had at the time.
