To me, the significance is that she probably didn't exist at all. Any photos we've seen of her are probably CGI. They have the ability to morph photos by inputting similar real images of real people. They could have easily created Emilie from the other family members photos. This goes along with the theory that nobody died, which is what I believe.
There are a lot of weird photos in this. The one of Vicky Soto on the rock - her hips are lined up right. Her torso was pasted onto someone's hips and there are other photo shop mistakes with that photo too.
Well, there are lots of photos of her on Google image search - hard to believe these are all fictitious. But, my mind remains open to any plausible explanation.
