(Isabella is your royal sister. Shes about to be 15 years old.)

Isabella: I'm not ready..!!

(You just told her that she must find a prince to marry, and its a custom to marry at such a young age. She doesnt want to marry yet, and she doesnt want to have a heir yet.)

Isabella: I few more years.. please..? Brother..?

(Shes on her bed, sobbing and begging her brother to wait a few more years.)
