Continuity mistake: In Episode "Happily Never After": In the opening when the CSI team is looking at the puncture wound of Fiona Chisolm, there is no blood coming from the wound. It is actually mentioned that there is no blood. Then it is determined that she was dead for about 6 hours, but now there is an L-shaped blood drip pattern to the chest wound.
Audio problem: When Stella sprays Felix's chestnut cart with Luminol, she visibly stops, but the sound of the spraying continues. (00:35:40)
Plot hole: In the beginning, they state that "Wendy" fell on the bus at another location. Don quickly states the bus was parked in the same location all weekend. Later, they find the primary location and find a window and hypothesize that a bus could've been parked outside the window, and that's where she landed on it. It's weird that they wouldn't check out the parking spot for the bus right away, only finding the spot once they find the classroom.
Chosen answer: Probably to broaden the scope of the show's plot and give the audience a chance to see the characters in a different setting, People act differently at home from the way they do at their workplace. By the ninth season, the characters would have become overly familiar and predictable. It gives the writers a chance to do something different with them.
