Other: In some of the "frozen" shots for Johnny's visions, people are supposed to be completely still but clothing is blowing in the wind at normal speed. Watch for people wearing trenchcoats and long clothing for the most obvious examples.

Other: In one of the final scenes, Bruce is talking to his father and everyone in the church is "frozen" in a vision. Watch carefully and you can see some people moving slightly.

Continuity: When Johnny, the health inspector and the men in bio-suits return to the school, there are four men in bio-suits. The inspector gives three of them orders on where to search for clues and the fourth one seems to have magically vanished.

Continuity: Why does Johnny have trouble getting into the booby trapped room? He shouldn't, as it was made clear in the previous episodes that he can freely explore the scenes in his visions and see things the person or object touched did not. Why is he suddenly limited in this episode and never once previously, and never again in the series?
