This episode was VERY funny and VERY imaginative!
Greg and Sara's case would never get you to beleive who actually did it! The so called murder was very creative and a bit far fetched but definatly believable!
Catherine and Vartann have a disagreement and he becomes jelous and Catherine reveals to him that Sam left her some of the casino which he is not happy about as she didn't tell him. She also confesses to him about her "rape" in season 7 when she went with a "friend" to a concert, as if on cue Nick turns up with results.
The humour with Hodges and the animals was also very funny. Both cases were good, and believable while both were not actually murder; they were accidents.
This is probably one of the best CSI's and one of my personal favourites, along with classics such as "Table Stakes" from the first season. Lots of people seem to not like this season, but hopefully, after this episode, people will realize it is still very good even without the likes of William Peterson and Gary Dourdan. :)
