Tropes featured in this episode:
- Answer Cut: to the Armor-Piercing Response below.
- Armor-Piercing Response: Edward figures that the only way to send the ghost back is to have someone from its life that it took orders from to tell it so. Lily has this to say:
- Lily: But, that can only be one person.(Cue engines from both fleets being stunned into silence.)
- Darker and Edgier: Compared to the previous episodes, this one is.
- Driven to Madness: A poor woman makes the mistake of daring to look into the ghost's coaches and is revealed to have been institutionalized afterwards.
- Enemy Mine: The Nor’ Easters and the Midis team up, and it ain't for business reasons.
- First Appearance: Of Kate, a Palette Swap version of Lady.
- Shout-Out: The night Edward has his encounter with Arthur's ghost, Edward's driver tells Edward that his son has just returned from his trip to the United States, and went to the premier of an animated picture and can't stop raving about it. He can't remember the title, apart from the words seven dwarves.
