Yeah she gets to know little parts every time. First in. Skypiea, then in FI and now in Dressrosa. I'm guessing they will have defeated the Donquixote Pirates at least in chapter 800.

Also, if she does find out the whole history then,she isn't the main character. They have other reasons to keep on sailing, lik getting the OP.
