You know, the significance or non-significance of that TV Guide photo does depend a lot on who at TVG magazine originated the blurb. If it's their person who might have been given access to the teams before the teams started filming, and they get the media review copies of the episode, then it may be significant. On the other hand, it may be a media-induced red herring. Depends on who it was, and whether they're given anything as guidance.
And since that item is unsigned, I guess we'll never know for sure.
