theon wasnt ned stark kid he had with a side chick, he was basically a hostage to make sure his dad Balon didnt try to flex again because in that world if you dont have sons the bloodline cannot continue
So thinking that they are his and legitimizing a b*stard is the same thing?
So a king could 'legitimize' kids that have none of his blood? Does this mean Theon could've been 'legitimized' as a Stark?
