I think we're now seeing real Hillary again, or a great copy. The face looks old, the nose has the hump. I don't know if she's back to her flats (shoes).
Old Hillary indeed vanished on or by 9/11/16, apparently she's the woman that was thrown into the van like a sack of potatoes. Debate Hillary was a different woman: shorter (wore heels to gain the height back; orig. Hillary wore flats), thinner, younger, no neurological symptoms, straight nose with no hump.
But on "purple night" after the election, it seemed that original Hillary had reemerged and has been with us, unfortunately, since.
