I dont get why he is jealous. He got her through college working 3 jobs. Shes successful because of you, those would be OUR accomplishments. Also if she can afford to pay for the 2 of them why doesn't he start bettering himself, like looking for a good job or studying? I think what makes this disappointing is he just gets thrown a system even though he and his sister are in such a good situation now. It'd be more interesting is if the way he got his sister through college was because he was a crime lord and then she somehow found out.
