Factual error: In a number of episodes people are shown eating and drinking in the laboratories. For instance, in "Miss Willows' Regrets" Nick and Greg are seen eating fried chicken in the lab, and in "Overload" Sara eats a sandwich while watching Grissom experiment with her deli pickle. There are other examples. No reputable laboratory (which this is supposed to be) would allow its staff to eat or drink while in the lab. It is basic scientific protocol to prevent contamination of samples or the person picking up toxins on their food.

David Hodges: You know, you and me, we're not the marrying kind. The intricacies of our nature can't be understood by just one woman.
Gil Grissom: Would you close the door, please?
[David Hodges shuts the door with himself still in the office.]
Gil Grissom: From the other side.
Trivia: For those who don't (or can't) read American Sign Language, at the end of the episode, Grissom says to Dr. Gilbet is that his mother lost her hearing when she was eight years old. He once asked her what is it like to be deaf, and she told Grissom (who loved to swim) that it was like being underwater. She also taught him that being deaf does not make one inferior to others. Dr. Gilbert then replies that she teaches her students the same lesson.
Question: Why would Catherine take the blame for the lab explosion? If anyone was to blame it was Hodges. Since he accidentally turned on the hot plate and even admits that sometimes it gets switched on by others accidentally, if he had bothered to make sure he didn't switch it on before leaving the room, the explosion never would have happened.
