Continuity mistake: When Father Bruce explodes, Nica gets covered in blood. In the final shot, we see his head fall to the ground, she's no longer covered in blood. The blood returns the next time we see her.
Continuity mistake: When Andy shoots up Chucky, Chucky lands on his knees facing away from Andy. But then he's facing Andy as Andy fires the rest of the bullets into him.
Revealing mistake: In the final shot of Father Bryce exploding, where we see his head falling back down, it seems to hit and bounce off something that isn't there. Likely it bounced off some sort-of rigging that was painted out digitally.
Revealing mistake: When Father Bryce explodes, the second shot looks incredibly unnatural. Much of the blood and pieces sort of vanish, and the lighting doesn't quite match, revealing it's some sort of added effect.
Continuity mistake: Towards the end of the exorcism, Chucks' arms are or are not being held down, depending on the shot.
Continuity mistake: When Chucky bites Father Bryce, as he stands up, the amount of vomit on his forehead changes.
Continuity mistake: When Chucky passes out during the exorcism, Father Bryce gets close to his face and starts whispering; the side Chucky's head is turned towards changes between cuts.
Continuity mistake: When Chucky taunts Jake about killing Nadine and Gary, you can briefly see the edges of the prosthetic cut on Jake's face.
Continuity mistake: Right before Chucky quotes "The Exorcist" and tells Devon his mother "sucks cocks in hell", he's being restrained by multiple people. When it punches into the closeup, there's suddenly no hands on him.
Other mistake: When doll-Jennifer is hit by the truck, we see a close-up of a puddle of blood reaching Tiffany's feet, but the doll's body is a solid 10-or-so feet away and is in pieces. There's no way it'd make a puddle like that, that would reach Tiffany's so quickly.
Revealing mistake: When the doll, Jennifer, gets hit by the truck, you can see pieces of the metal armature and wires sticking out of some of the bits and pieces that were used to make the doll stand up. You can also briefly see that Jennifer goes from looking at the truck to looking forward between cuts, but it goes by quick and is hard to see. Slow motion helps but isn't required.
Continuity mistake: When Father Bryce approaches Chucky right as the exorcism is about to begin, Devon goes from lighting a candle to walking up the steps between cuts.
Continuity mistake: When Father Bryce "suits up" for the exorcism, there's a stylish series of shots where we see him putting on his glasses from three different angles. Except he's looking in a slightly different direction in the last one, revealing it was different takes.
Continuity mistake: When the cashier at the diner recognises Tiffany and asks for a picture, he lifts his cell phone up twice between cuts.
Continuity mistake: During the standoff, when Dr. Mixter says "Do we have a deal?", right before the credits, Lexy is breathing VERY heavily in the background. But when it cuts to a closer shot of her, she's no longer breathing that heavily.
Deliberate mistake: When Jake hands Chucky to Dr. Mixter at the start of the episode, the doll he hands her is just a "stunt doll" as it's not moving or emoting like it is in every other shot.
Continuity mistake: When Jake gets angry and slams Good Chucky into the wall after he says "I didn't mean to do it!" at the beginning of the episode, in the first shot Jake is holding Chucky a few feet from the wall. In the next shot he's only a few inches from the wall.
Continuity mistake: When Father Bryce explodes, and it's shown from multiple angles over and over, the way his head flies into the air is different in some of the shots. In some of the shots, it flies straight up several feet into the air, while in other shots, it only shoots about one foot into the air and also shoots forward slightly, revealing multiple different takes were edited together.
Continuity mistake: Before the cops start interviewing them, Jake puts his hand on Lexy in a reassuring manner. It's not on her in the next shot.
Revealing mistake: When Chucky is sawing Michelle in half, as her body starts to split, a few times you can briefly see where her body has been "pre-scored" to split apart as the chainsaw moves down.
Answer: They were blamed for the death of Jake's foster brother, which was deemed a terrible accident, and they were sent to the reform school as a punishment. Presumably, when they had to leave the reform school given what happened, they were instead given community service as punishment.
