I don't think that I could stay in my chair after laughing at Fisi's realization of just how many half-siblings her brats will have and the rather laien nature of some of them.
Just casually telling her that you have upwards of 20 children in the nursery a few floors up that she had no idea about. I can see that being amusing. Especially when she learns I have a brood of 10ft tall hermaphroditic dragon daughters who's mother is bigger than my ship.
