As we go along, we'll be fleshing out our concerns re this new Dover as presented by NBC a few days ago. So check back for updates, edits & replies to this post.
AN is unconvinced by the new Tiffany Pontes Dover. So we discovered a youtube video made by Dover some years ago & we've added the new NBC video to this so we can compare both the appearance of the new & old Tiffany's as well as the sound of her voice.
NBC claims that, "Tiffany knows she’s not dead, and she did what she could to show the world as much." &, "The Tennessee nurse stayed quiet in hopes that her silence would quiet false claims of her death."
So... she completely disappeared for almost 2.5 years in order to help the world understand that she was not dead & not injured? Pull the other one NBC. Disappearing for almost 2.5 years can have no other effect that causing the world to consider her demise.
In the video, Tiffany claims she feared for her family's safety & was in receipt of death threats! Why would conspiracy theorists who were convinced that Dover was deceased threaten her with death? Again, this makes little to no sense.
Let's assess some of the optics.
Firstly, Dover is shown in what appears to be a very good sized house. Bear in mind she's a young, married mum of two. Her home appears to be more suited to a doctor in his forties than a nurse in her twenties or early thirties.
The new Dover's home also appears somewhat sterile. It's not just quite large for a young, working person, it's also in absolutely perfect condition. So is everything in the home, even the clothes the new Dover is wearing. Everything in the home & the clothes Dover is wearing appear to be pretty much brand, spanking new & in perfect condition.
Dover has a husband & two kids. Do you see the slightest sign in Dovers home that kids live there? There are no toys, dolls, or anything that a kid might like to play with. There are no brightly colour kiddies clothes hung over the backs of chairs, there's no brightly coloured pictures on the walls, there's no kids cups or plates visible in the kitchen & there are no crappy kiddies drawings magnetised to the front of the fridge door. In short, there is no sign whatsoever that the home the new Dover is shown in is lived in by normal people or kids at all. My missus suggested it looked more like a set of soap opera & I thought her home looked more like a show-house on a new housing estate.
Dover herself is seen smiling & raising her eyebrows in many of her old photo's & in the footage we culled from her youtube account. The new Dover smiles not once in the new NBC video & never raises her eyebrows, a habit she seems to have lost.
The new Dover also has pristine new clothes on, except in a couple of images where she in fact appears to be wearing the same hospital-blue top that she in seen wearing on the day or her vaccination. Her style has changed from casual, relaxed to conservative & austere.
