Okay, first:




And now thoughts: I like to think that Annie really was the woman in the red dress. Was that ever confirmed? If that was her and she died there, she lived past her death. I mean, she died, in purgatory she went back in time, lived forwards there until the point where in real life she had died. And in purgatory she lived past that point.
I wonder if she was the only one. If others experienced this, what was it like for them? And does everyone arrive in the past or do some people 'timetravel' forwards? Argh, this whole concept is so fascinating, I'm sad there isn't more to explore it. I wonder if more would work. Make a third show, explore all the interesting possibilities, keep it going for a long time by changing protagonists.
