Revealing mistake: At the start when the camera pans away from the dead body, the "D.B." swallows when he's supposed to be dead.
Audio problem: When Nick and Warrick find the dead man's flying equipment, Nick says "Bingo" but his lips don't move.

[To a room full of dead corpses, after Holly Gribbs was frightended into hysterics.]
Gil Grissom: You assholes!
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.
