Continuity mistake: As the episode starts, Lulu is snoring in bed. The purple head board of her bed is in the light in such a way that it is diagonally lit up from the top left to bottom right. When the angle changes as she gets up, the lighting has flipped so the bottom part is lit rather than the top. There is also a window that suddenly appears in the wall by her bed that was not there in the previous shot. (00:01:05)Quantom X
