Ohhhh She is burning his Office to claim she "couldn't find the ledge" That is a bit extreme lol. People will be able to steal from Cesar later if their are no records....why not prepare his mother with a different document saying Cesar gave them to his mother as gifts ? I mean she is his MOTHER, this makes more logical sense then "I burned my son's library down". Or It will just make Canaria seem crazy ...either way I see this plan back firing.
Its really impossible to care of Cesar's mother we have seen her twice now and she seems totally apathetic. Maybe she was scared of the Empress ? Who knows ! Since the writer of the story hasn't bothered to flesh her out. If she "died in childbirth" like so many other hero parents their would be no difference.
