I hate that even the younger brother is involved in this and not the princess, and just as he said he is the second candidate to the throne, when he should be the third. Noone is taking the princess seriously and decided that she must be a good girl waiting clueless in the castle. It would have been fine if the younger brother wasn't involved in this as well, but not that he is it shows that they aren't just protecting the young ones and that this is just plain sexism.
