(I'm sorry, I accidentally replied to the last post on the last page, this makes this one irrelevant, but I'll leave my question from it
When it was that Amy told the Doctor she's not pregnant? It was much later than seeing the Eye Patch lady, right?
Anyway, I doubt she was abducted when she was the Silence on the ceiling. It is the best spot to do it - the marks on her face make you wonder what happened in there, something did happen, and there is some mystery about it and then she saw the Eye Patch lady right away. But she must have already been 3 months further in the pregnancy at that time, so I think that makes it improbable, and I think all clues suggest that she was a ganger all the time, and there's little reason for the clues to be misleading about something like this.
Though the Eye Patch lady said “No, I think she is just dreaming”, which suggests that it is the first time Amy's mind became aware of her real surroundings, and perhaps also that the Eye Patch lady didn't know about the ganger at that time. Does that suggest that the abduction was a recent thing?
P.S. I've got a feeling that this arc will be a much better watch once it is resolved. Suddenly the apparent confusion and non-sense will have some meaning. I look forward to watching all those episodes again once everything is solved. I hope that the next one doesn't end with a cliffhanger again... And I hope it solves everything... So far... (And if it introduces a mystery, it's an entirely new one, still resolving all the old ones)
