Factual error: Brian is sitting on the couch smoking weed. Joe knocks on the door and Brian just waves the smoke from the air.

And Then There Were Fewer - S9-E1
Continuity mistake: When James returns to the lounge to find everyone there, they all accuse him of killing Stephanie, so they walk over to the dining room with James at the front followed by Tom and Priscilla behind him and Joe and Doctor Hartman behind them. But when they enter the dining room, Tom and Priscilla are no where to be seen and it is now Joe who is behind him. Also in that same scene, several other characters change position. The people who are in the room are Peter, Chris, Brian, Quagmire, Joe, Bonnie, Diane, Doctor Hartman and Seamus and the rest of the guests aren't seen. So when they enter, Diane and Chris are at the back followed by Seamus, Quagmire and Bonnie in front of them, followed by Doctor Hartman, Peter and Joe at the front. There is then a shot of the chair completely empty. Yet in the next shot, Brian has suddenly appeared next to Joe out of nowhere. Then in the following shot, Diane is still at the back but now more closer to Bonnie and both Bonnie and Quagmire have changed positions and Seamus is now at the back and Chris is suddenly next to Quagmire at the edge of the right hand side of the screen and Peter is now behind Joe. Then the shot cuts to James and the shot cuts back to guests. But now Peter has appeared next to Doctor Hartman again and now in front of Joe and not behind him. Also Diane is now no longer at the back but in the middle towards the left of screen and no where Bonnie and Seamus is now partially in front Bonnie. Then when the shot cuts to James saying he is a member of MENSA and a huge hit with the ladies, there is no sign of Brian standing next to Joe. Then in the shot before the lights go out, Diane is now at least ten inches behind Bonnie and Lois has appeared behind Seamus out of nowhere. Then by the time the lights go back on again, Lois is now in front of Joe and all the other guests have appeared in the dining room. Then when Seamus says "Look", there's no one in front of him even though loads of other people were there in front of him before the lights went out. Then the shot zooms out and we can see in the shot are Doctor Hartman, Priscilla, Joe, Brian, Carl, Mort and Tom. Then when Joe says "Nobody touch the knife", it's now Seamus, Bonnie, Quagmire, Lois and Derek in the shot. Then when we see Peter and Chris in the shot, the shot zooms were Joe appears we can see Quagmire, Lois and Bonnie behind Peter even though they were way in front of them a couple of seconds ago. No way could they have all moved that fast, not with all the other people in the way. (00:13:40)
Answer: Lacey Chabert was the actress who originally voiced Meg in early episodes. She left of her own accord due to being in school and other acting work; Seth MacFarlane has stated there was no tension with her leaving, but it makes for a handy joke for the show.
