Those scumbag WN will probably kill her. You can get the date by figuring the princesses age. (Was just mentoned wasn't it?)

They may not get her right then, maybe they decide to sty for a while and treat the FM bad, and when she steps in. ):

Also, this is a bit off topic; but I'm guessing after the Straw Hats, "destroy" Fishmen Island it will set them up for their first run in with an Emperor. (May even see the SH Flag above the FM Palace when they leave.)
