This scene seems to imply that nobody since Roger was able to steal/read Big Mom's road Poneglyph (Until Brook of course).
So what do you think Kid is referring to when he says "I wounded one of her commanders, stole what I was after and left", I checked the official translation and it says the same. Is he referring to a rubbing of the Road Poneglyph but Big Mom is unaware he stole it? Or is he referring to something else?
