I'm having an issue when taking the princess' quiz. I've tried all the nickname options on question 3, but she says they're all wrong. Did I miss something?
To answer the nickname question, you have to unlock that option from another character. You can talk to Perle (the maid) to get a hint if you get stuck!
(And if that's not helpful, here's another more obvious hint: Talk to Emeric while wearing the last item you haven't used for any other puzzle so far.)
