Very true.... and it could very well be that they didn't get married, like we saw with aladdin! everyone was sure by the end of the first that they were married.... when they didn't really officially tie the knot until the third flick!I don't really want to get into technicalities but i will anyway...
It doesn't show meg and herc getting married, same goes for belle/beast although we assume they do.... So, really the neither of them are princesses on-screen.... The only people who are in fact princesses by birth or by on-screen marriage are pocahontas, snow white, ariel, cinderella, jasmine, kida, aurora, and Eilonwy.
Oh... and another thing... I always wanted to see the black cauldren... and i never got around to! is it worth my while?
