Why bringing her in if he don't want to take care of her and if she is a weakness ? He could have just pretend that she stole the ring somehow and just take back the ring and leave her there. Since she doesn't have golden hair and eyes noone would have thought of her as a royal, problem solved. Or just take the ring and kill her. But why bringing her in and risking to expose a weakness if it's not for love ? She just trade her old prison for a golden one. She needs to find a way to get the fuck out of there without having to live on the streets, as quickly as possible.
