Well let's face it- all the adults in his life that reported the abuse and told Jonathan they felt Emily was abusing him, didn't help the poor child at all. If anything, I think she probably abused him even more, every time one of them either reported it or tried to talk to his father to get him to see the light. His father chose to ignore every single sign, every single bruise. All the articles and reports that we have seen clearly show abuse was happening, and we're complete strangers, and we all can see the abuse that occurred. Nothing short of kidnapping him and placing him in a safe home far away was going to save him, because a certain individual put someone else ahead of his own son. He loved her so damn much, that he didn't allow his family to see Lucas ever again, after they tried once more, back in November, to open up his eyes.
So think about it- Daddy doesn't believe you, Daddy doesn't believe that Emily is being mean to you, that Emily doesn't like you anymore. Why in God's name would this poor child not vomit every day? He was afraid of more hits coming, more threats, afraid for his own life, no one around to protect him because everyone was told to back the hell off, so they did. Legally, they had no recourse, because DCF and police closed up the incidents and let this child stay there, in spite of the fact that the witch didn't have custody of her own children from a previous relationship.
