Two new engines arrive on Sodor, both of whom have unique introductions. Meanwhile, Mr. Zorro receives some bad news.
This episode provides examples of:
- Big Damn Heroes / Mundane Made Awesome: Peckett extinguishes a fire on Henry's fuel train by smashing into the milk tanker on his own train to rupture it and spill its contents on the fire, putting it out in short order. Both he and Micky refer to it as a "milkshake", and Peckett explains such an unorthodox maneuver was common on the Somerset and Dorset Railway during summers.
- Jerk with a Heart of Gold: Francine, proving that, unlike Hyacinth and Rose, not all snobbish bogie mounted coaches are that snobbish.
- Replacement Goldfish: Samantha and Peckett are this to Lily and Colin.
- Ship Tease: Between Reginald and Samantha.
- Wham Episode: Mr. Zorro is diagnosed with early-stage lung cancer, and resigns as controller.
- Wham Line: Mr. Zorro names Basil Corbett as acting controller. If you've seen the preview for the next episode, you know that the engines are not going to take this well.
- Wild Mass Guessing: In-Universe example, with Mr. Zorro being so scarce that workmen are beginning to make theories.
