Continuity mistake: When Cho finds Archie's notebook under the bed, he turns to near the end and starts reading Archie's entry. But the position of where Cho has the notebook open changes, depending on the camera angle.
Revealing mistake: Any time any character is driving a Suburban, or any other vehicle with a column mounted shift lever, the shifter is in park while they appear to be driving.
Kimball Cho: What do you need?
Patrick Jane: Backup.
Kimball Cho: I don't like it when you say you need backup and nothing's happened yet.
