When Linda is sitting at the counter in the diner her cup is facing to the left and her hand is nowhere near it, but in the next shot it is facing to the right and she is holding it, and in the next shot it is facing to the left again..
A few chapters (can't use the proper word) back, Linda had had her hair cut short. In the previous "visit" she had long blond hair. But now, it's back to the bob doo.
