The case is itself intriguing. A sweet teenager has a rare form of cancer and has a death sentence. If this were a conventional medical drama, there would be a miraculous recovery. Here, that is never the case. Other than encouraging her to enjoy the time she has, she is not going to make it. The deduction is excellent and the characters are driven by love. Brennan is her usual autistic self and Booth gets in the way at first; however, they follow through with their investigation. There is one thing I take issue with. To call a poor man with horrific cancer a "serial killer" is just wrong. The serial killer is the one who went after untested grafts and sold them in an illegal way to unsuspecting medical facilities.
