I liked most of this episode pretty well, but there were two things about it that I didn't care for. The first is that the show was a particularly gruesome one, similar to that of "Butterflied" and also the one where the chef was ground up in a meat grinder. I thought that the scene where Doc Robbins was explaining to Gil how to mount a human head the way an animal is stuffed and mounted was overly long and quite unpleasant to see.
The other thing I didn't like was, you guessed it, Grissom and Sara and...a dog? Oh come on! Are we supposed to believe that because Grissom is in wuv with his underling, he now has made room in his life for a pet? This is a guy who lived in an antiseptic clean townhouse where the only creatures he kept were behind a glass stuck with pins, and now we see him and Sara on the bed with a fairly large dog. Yes, I know that the dog really belongs to Bill Petersen, but it was still an unbelievable scene. In addition, aren't they worried that Catherine might just drop in on Grissom and discover the secret relationship? She'd probably be more surprised to see that Grissom has suddenly become an animal lover.
Changing subject...I was quite surprised and a little disappointed that Greg would call that woman who bit him a bitch. I understand that he was shocked and in pain, but it was totally out of character for him to call a woman a bitch, especially with her still in the room.
Nice to see Archie again.
I'll have to watch it again to see which portions of the episode I forgot to mention.
Edited because I was glad to see that Greg got a tetanus shot and some antibiotics. Human bites are so nasty!
Catherine and Greg's scenes were really good. Glad to see that she cares enough about Greg to get him to laugh at his misfortune. I liked her line to him about him having a great year as opposed to a bad year (because he's been doing a great job).
