Continuity mistake: At the end of the episode, the team and their SUVs are spike stripped and then hit by a semi. When the team is shown in the SUVs and when the SUVs are shown hitting the sticks, the SUVs are eleventh generation Suburbans, but when the semi is shown hitting them, they're ninth generation, at least nine years older.
Continuity mistake: They keep showing the aerial view of one type of jet (such as Gulfstream 100 with its rectangular windows), but the inside shots are always in a "heavy" Gulfstream (such as Gulfstream IV or Gulfstream V, which have round windows). Also, the tail numbers (the N-numbers written on the engine) are always different in the aerial views. Some end with GV, some with SP etc.
Continuity mistake: When Reid is talking there's a big crack at the top of the window that might be a problem since they're supposed to be flying. Then a few seconds later they cut back to him and it's filled with putty. (00:05:00 - 00:06:00)
Continuity mistake: After Emily shoots the unsub in the head and he falls on the bed, the gun falls beside him. A second later they show her walking over to his body to remove the gun from his hand. (00:51:00)
Protection - S10-E22
Continuity mistake: In the final stand off, Daniel fires 16 rounds through the door/wall at the team. We've already been told his gun only holds 14 bullets. Not to mention without reloading he fires a few more bullets shortly afterwards.
Continuity mistake: The clock on the bomb's secondary timer doesn't match with reality while Prentiss is trying to defuse it - going from 15 seconds to 10 too slowly, then skipping the final few seconds so it can end on 1 second remaining.
Protection - S10-E22
Continuity mistake: The vigilante is on the couch drinking vodka. First shot it's in his right hand then the next shot it's in his left.
Magnum Opus - S8-E13
Continuity mistake: In the scene where you first watch the killer drain a victim's blood, the upper part of the glass jar is coated with blood, but when he puts it in the fridge this part of the jar is clear. On the other hand some of the jars in the fridge are still fully coated with blood, which shouldn't be as the blood had the time to gather at the bottom. (00:07:15)
About Face - S3-E6
Continuity mistake: This episode is a flash back to when Agent Gideon joins the team, but agent Prentiss is already a member. She didn't join until season 2 (when agent Gideon was already an established character).
Answer: "The Boogeyman", s02e06. Spoiler alert: The kid is Jeffrey Charles and at that point he had already killed 3 other kids. Jefferey basically hated and resented other kids after his mother abandoned him and his father spent a lot of time with other children because of his job. Jeffery would lure kids Into the Woods and then beat them to death with his bat just because of hate, no particular "reason." The scene you're describing, Jefferey agrees to walk Tracy home when her "buddy" leaves her (at this point the FBI announced there's a serial killer on the loose and kids should walk with a buddy). Jeffrey gets mad at Tracy for walking too slow and for complaining, and he takes a swing at her, causing her to flee Into the Woods and have Jeffery chase her.
