I guess once you find out about the drug causing "scarifying" hallucinations the phone call at the beginning makes more sense (why there were pauses and why we never heard anything besides the voice on the other end of the phone).  Adams' character seemed odd to me that he would pick up and help the sister out so easily, but it did sound like he was a smooth operator, so perhaps not so odd (although he did go to lengths to help her out).  Not the best episode, but definitely not the worst, either.
