Honestly princey boy isn’t even that bad he’s just a (spoiled) brat being lead by the nose by his sister.
He hasn’t really shown any aggressions or discrimination towards blondina that wasn’t brought on by outside influence, at times he even talks to her rather freely with a mutual stance (as in he’s not out to get her)
I don’t need some grand redemption for the brother but I want some sort of bond to form and communication, with him maturing and questioning his sister
