| Plot Function | Moves a discrete mystery forward | Influences season-long stakes or character growth |
| Casting Notice Language | Often listed as “guest star” or “episodic role” | Labeled “recurring” with potential for extension |
| Media Coverage | Typically highlighted at episode launch | May be referenced in season previews and wrap-ups |
