Grissom has to divide five cases between himself (an autopsy with Dr. Al Robbins), Cath, Sara and Greg. Meanwhile Hodges calls Archie and two other lab rats together to attempt inside to find the connection between the serial killer's four crime scenes, by studying the signature miniatures: perfect scale models he left -the second however was delivered later, after a modification- over nine months and the meager case files in Grissom's office. By surprise a live rat escapes from the autopsy corps. The other technicians furiously abandon him when realizing Hodges was not asked by Grissom, but he perseveres and finds a bizarre material common point... Written by KGF Vissers

I loved this episode
7 July 2016 | by shittingSee all my reviews

I really loved this episode. I think it could have been a hair better when it comes to all the lab rats' participation. However, I enjoyed the premise and overall the execution was well done. Seeing Wendy doesn't hurt, she's absolutely gorgeous! Most importantly the humor was through dialogue. It was not born from a situation, like a farce. This was a smart way to do it. They put a lot of thought into this episode, especially with each lab rat dropping off until only Hodges is left. That I think was artistic license, and I'll have to ruminate on why they wrote it that way. Perhaps as each character drops off, the story and the interactions become more personal.

Will definitely watch again.
