That is a difficult one. Because no one can 'get' another person to do anything, without breaching boundaries. And those boundaries are just as importent and deserve just as much respect for a 13 year old as they do for a 30 year old.
Has he 'dealt with' the abuse? No, probably not. But most likely, he is not yet ready to. He is currently physically safe. His perp is in jail. And he knows that there is counseling and other help available to him if he chooses it. I think that is all that really anyone can do right now without forcing something on the kid.
I wish him luck.
