Empty Planet - S2-E8
Factual error: This episode takes place in current Seattle today (no illusions of a "Seattle in this fantasy world") including using Google earth as a means of identifying a specific area of action. But all the street signs in this episode are blue where as all street/interstate signs in Washington State are green with white letters.
Empty Planet - S2-E8
Factual error: In the opening sequence a bomb is detonated on a bus in Seattle, in the vicinity of the Seattle Center/Space Needle. Right after the explosion, as people are moving towards the now smoking bus you can see a palm tree in the background. There are no large palm trees in metropolitan Seattle and absolutely none in this area.
Factual error: Reid says that it's been speculated that Mary Jane Kelly was murdered in a flat rented by the killer - this is completely incorrect. She was murdered in her rooms, where she'd been living since early 1888.
No Way Out - S2-E13
Factual error: Gideon says that Frank is the most prolific serial killer ever, with 177 victims. This is incorrect - Pedro Lopez murdered 350+ young girls and Luis Garavito murdered 300+ plus girls.
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.
