This episode was a huge improvment over 11x01 and 11x03. The start was creepy, something i have never seen before in CSI. The idea of a forensic proof serial killer was great, again something CSI has never done before. It was different and i loved that they didn't catch him despite all the evidence they had. Sqweegel himself was very creepy espically as everything he did was done by the worlds most flexible man. Its great it wasn't special effects. I really liked the motives behind the killings. Knowing everybodies secrets giving them an oppurtunity to confess. This would make a very good serial killer because everybody in Vegas has a secret. I am writing this after watching the finale. I have found out the sqweegel will be a focus of season 12. I think he will target the team particually Brass because of how they handled Haskells killing. To sum up this was a perfect episode. Full of suspence, they didn't catch him. I reminded me of the old school CSI.
