>>46014044Make him an antagonist who becomes a replacement to Rose after Leon refuses to help him. Rose couldn't use Leon, so the next best thing would be his brother, right? Hop wants to be strong, he can't beat you, he got his ass reamed by Bede, all he wants is to be someone like his big bro.
Rose sees this and preys on this ideal and promises him power if he assists in helping him catch Eternatus. He manages to do so, using you and the dogs to assist him and takes Eternatus for himself to fight you again.
You still win, crushing his hopes once more but he is consoled by your actions. Then the same shit with the dogs happens in post game, showing his actual change in character following these events.
