I know, there's actually nothing Brazilian about except her "background". They portray her with a Latina flair and not a Brazilian one. Her complete name includes Bonilla, which a surname of Spanish origin. One of her other surnames is Corvalho, which is a misspelling of Carvalho. It seems like the writers didn't really care to establish her Brazilian identity, but rather give her a Latin one. They should have just made her Venezuelan, IMO.
