this is totally off the wall but here's a different perspective... the recruiters told Juliet that she was special... there's that word again... I think that Juliet may have some powers similar to Walt and she may have put that thought out there and it manifested it's self... also she may have helped her sister get pregnant with a little of her mojo...
She was depicted as a wallflower and completely under the thumb of her husband... she probably kept herself in that position because she believed him so much... the recruiters were the first opportunity where the focus was on her... she was given an opportunity... she wanted it and boom she makes things happen...
Like I said just another perspective.... humor me....

Innnnnterrreessssting.

Now that you mention it, it is a little reminiscent of Walt's bird flying into the window.
I still feel like it may be a bit of a reach, though, when the story that Alpert & Ethan caused it still supports the plot of the show as well. It's not set up as a mystery, so IMO, I don't think we should make it into one. But I do love hearing your mind...sparkle.
