And Then There Were None - S6-E16
Revealing mistake: Samuel is very much dead, laid out on the table in the canning factory employee lounge, but as Sam stands over him, talking about whether or not it was right to gank him, you can see Samuel's chest rising and falling as he breathes. (00:26:30)
Revealing mistake: Davis, the psychiatrist, is the second man to be killed. Although he was shot at five times, only the first two wounds, which are the highest, give blood, while the lower and later three do not.
Revealing mistake: When Agent Hotchner receives a text from JJ while interviewing the suspect, it is actually a screenshot. You can see Camera Roll in the upper left hand corner, "2 of 2" where JJ's name should be, and the Share/Play/Delete banner at the bottom. It is covered by Agent Hotchner quickly tapping on the screen to clear the banners. (00:16:15)
Revealing mistake: When Allison is "seeing" the Massey house going up in flames, James flinches when the painting falls off the wall behind him, even though it is only supposed to be happening in Allison's vision.
