OHH HE** YES I'm so ready for this!! 
I'm thinking she's a version of our Valletta that possessed the book character, had her powers and was successfully married off to the Prince as planned due to the tiara that was on her head! It must have been tough if she decided to end it all  I don't think she'd be a version of the real book Valleta as her father had no interest in her since the original Valletta had no powers  I'm hoping they both heal each others loneliness and end up happy like the main characters
