I have seen all CSI episodes and they continually create amazing episodes. This episode is absolutly amazing. They also introduce the new character in a very plesent way and she is going fit in very well with the rest of the characters. The mystery of 'who done it' is cleverly presented as (almost) always and classic to the CSI writing method. It is an extremly powerful episode in seeing how everyone is dealing with what has transpired in the last few episodes and should prove to be a great transition episode for all the characters. The phychologist presence is not overdone. Her presence, in classic style, show how each character is dealing with the trauma. It is extremly rare to see a perfect introduction of a new character, an wonderful murder mystery, and the character development of many of the characters in one episode such as this. It was just amazing to watch.
