Two wide-mouthed bottles appear out of nowhere on Miss Halloran's desk after Miss Withers searches it and finds the liquor.

When Leland claims he has written the punishment word 82 times, there are at least 86 instances of the word on the blackboards.

Withers opens the right-side bottom drawer of Louise's desk which shows a wide lid jar, she reaches in but then is shown pulling a bottle of liquor out of the left-side drawer and after taking a drink returns the bottle to the left-side drawer. Two jars are now sitting on the desk top so it appears part of the desk search was edited out.
