I thought it looked familiar…..
Plus, I wonder if Scavino purposely chose bad grammar.
"who I can trust" instead of "whom I can trust"
Something about WHO and wearing masks?
Come to think of it, it appears as if the wall hanging doesn't have a mask on, as if he took it off after so long, and his skin is pink from no sun while the rest is tanned.
So the figure was masked, as if unable to reveal himself. Now he's unmasked, and will reveal himself.
