Continuity mistake: At the end of the episode, as Spike's getting his T-shirt on, from one angle he gets his arm completely through a sleeve, then we cut to a different view and he's still pulling it on.
Continuity mistake: In every other episode it's seen in, room 314 is a room directly off a corridor, but in "The I In Team" Walsh walks through the door off the corridor, then there's another shot of her walking through a door. Where did the second door come from? (00:13:50)
Continuity mistake: The first shot of Maggie Walsh being impaled from behind with the skewer indicates that there is no one standing close by, judging by the amount of negative space around her. However, following shots reveal that the skewer is coming straight out of Adam's wrist, therefore he should have been visible in the previous shot.
Continuity mistake: When you first see Adam lying on the bed, before he wakes up you see his human side of his face on his right side. In the next scene the camera is over Maggie Walsh's shoulder and the human side of his face is now on the left side. Then just after he stabs Maggie it switches back again.
Chosen answer: He had larangitis and because of the shooting specifications they had to have him shoot the scene with a bad throat, they then re-recorded his lines and dubbed them. At various points during the scene and indeed the episode you can see him touch his throat or rub it.
