eh, wait... Kyo is missing from the family photo... kyo is missing from the family photo.
If this is not an error or purposeful omission (due to "Family") then this has huge implications.
My theory is that Caato can erase the existence of whatever she hides between the cards and that's where the flashback man and Kyo currently are. (this having the theory that she's the actual main villain of the part in mind, otherwise then the evolved Paper Moon King is even more terrifying, but I suppose it wouldnt be the case because he might have a reason to use it on Norisuke since he's seemingly trying to hide the body)
