Won't Get Fooled Again - S1-E3
Audio problem: The video game Penelope is playing is supposed to be Tetris, but the sound effects are from the Atari 2600 version of Pac-Man. You can hear Pac-Man die four times during the scene. (00:12:20)
Audio problem: As Scott McCarty is shot there is no sound of a shot being fired, suggesting a silencer, however as the assailant's rifle is pulled inside the car you can see that the weapon has no silencer.
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.
