The parents did not harm Lonzie. Imagine, you raise a sweet little baby into a boy, who becomes a man. It would be hard to separate those fantasies you had while raising him from the real truth about who your kid has become. But eventually they will come to terms with it. They are being fooled by Ebron because they want to be. They are in denial. But clearly they are also slowly letting the reality of who he has become penetrate. In the meantime, they haven't done anything wrong to anyone, and like every parent here, they are holding on to hope that they don't lose their own 'baby' too.
