No doubt: this was the best episode of the season. Tension was created on the first seconds when it came clear to all viewers that the drama around the investigation would be exciting. The idea to insert the voiceover of a child whispering along with strong scenes showing a brutal murder filled the purpose.
All CSIs worked very well playing their caracthers, as usual, but the performance of George Eads as Nick Stoke was brilliant, specially on a storyline combining a case that could bring back to him old memories of his recent trauma.
The final scene showed the importance of CSI's job. It was very emotional and very rewarding to watch.
