Apologies if this was mentioned in the last few pages, but after researching today I'm fairly certain that SS24A clue is either relating to Legendary Truth or Boris specifically.
It's already been proven that the skull is the exact same one as used in last year's tribute store, but why bother to make it half-black/half-white- unless *that* is the big clue, highlighting the black and white to specifically lead to False Idols Pt. 1.
Maybe it's a stretch, but the clue already cuts off the jaw of the skull- maybe it is just comic book related, but why edit that skull even more unless there's more to the clue?
