Could Ven be Sora's older brother or something
I just went over this, good lord! Why don't you look back a page?
Also if you don't mind me asking, why didn't Ven's heart create a nobody when it came out of Sora? Namine was formed from Kairi's heart and Sora's body right, isn't this technically the same thing?
EDIT: I mean I know Roxas could have been an explanation of this, but it seems if Sora had three hearts in him it would make three nobodies.
Whoever said Ven's heart left Sora's body?
Kairi's heart had a place to go.
Sora's heart had a place to go.
Ven's heart didn't have a place to go, and thus, stayed.
