I really think there is more to the Ray's story. I wish Price would have asked how Davidson got the drugs, where did the money come from. Since this was a 2nd time he had drugs in the house the Ray's would have known better then give him money, so did he steal from them? Plus remember Dr. Brown said that she did not need to test Davidson she could tell he was on drugs from the way he was acting, so another words she did have test in the house and this was an on going thing. I do however think they tried and cared very much, I don't however believe they have kept in touch with Davidson.
