it's the angle. not always the case but here it is the case
on the picture on the left, his right nostril (our left) is curved outward.
in the picture on the right, that curved nostril is in the shadows.
the rest of his nose is symetrically proportioned so compare it without looking at the deformed nostril. it is the same

good point

i know ppl are alive that we thought dead, that there are body doubles and all-out replacements.
schiff being replaced would not shock me.
im just observing these two images and from that, my belief that i conclude, is that the men in these two specific inages are one and the same
