- All Myths Are True: In-universe; The "Witchfield Worm" turns out to be a large Labyrinthodont that got marooned in the present.
- Artistic License – Paleontology: The Labyrinthodont's appearance is drastically different to how it would've looked in real life.
- The creature had rough scales like a crocodile instead of the smooth skin it would've had in real life.
- It was also far larger than any known species of Labyrinthodont. It was large enough to be able to rear its upper body up like a snake and prey on cattle.
- Despite being an amphibian, the creature was able to spend way more time away from water than it should've.
- Buried Alive: Ethan attempts to do this to Emily.
- Damsel in Distress: Emily's role in this episode.
