This episode provides examples of
- The Maiden Name Debate: Paired with Single Line of Descent and a reversal of Lineage Comes from the Father. Apparently Beverly is the first Howard woman to not keep her maiden name and pass it to her children since at least the seventeenth century.
- Our Ghosts Are Different: Ronan is a spectral entity made of "anaphasic energy".
- Scotireland: It's supposed to be a planet of Space Scotsmen, but the accents of the people are hardly Scottish. Amusingly, the actor who plays Ned Quint was actually Irish.
