In spite of the halo being a symbol for sun worship… I took the painting of the sleeping child (with the halo symbolizing innocence maybe) on the man's back who is carrying him is supposed to represent his sons featured in the picture. It seems as though Musk is telling someone his children are innocent/unaware of what he's been involved in and he's asking for them to be spared. I notice "Grimes" didn't show up at the Vatican.
