However, it's a common television trope to use subtle clues or oddities to hint at supernatural activity or unresolved mysteries. If the scene you described was indeed a significant detail, it's likely the show's writers intended it to be a foreshadowing of something yet to be revealed.
Possible interpretations of the scene could include:
* The sixth person is a ghost. The most straightforward explanation would be that one of the people in the group is actually a ghost, and their presence is not registering in the physical world.
* A visual error: It could be a simple mistake or a stylistic choice by the production team, intended to create an eerie feeling but not necessarily with any deeper meaning.
* A plot point for a future episode: The scene might have been planted as a seed for a later story arc, where the "missing shadow" becomes a significant element.
To get a definitive answer, you could try:
* Rewatching the episode: Look for any further clues or mentions of this scene within the same episode.
* Consulting fan forums: There are likely online communities dedicated to "Ghost Whisperer" where fans have discussed this scene and may have theories or insights.
* Searching online resources: Websites that provide summaries or reviews of the show might mention this scene and its possible implications.
Remember, television shows often leave room for interpretation, and the true meaning behind a specific scene may be up to the viewers to decide.
