Actually, I find almost all the information here would be spoilers to someone who hasn't seen the show. For example, we frequently talk about the different time periods and story lines and refer to parallel time. Part of what I originally liked about PT was the mystery when it started. How could those people be in that room, dressed differently, leading apparently different lives and why couldn't those viewing them get in, or be seen and heard by these other people? It was such a puzzle, and then finally we got the explanation. It always seems a shame to me that almost everyone is aware of what this is now and don't get that sense of bewilderment.
