Betty's #10 is shown on the roller derby bench with her coach, but then we see stock footage with #10 skating. We cut back to the bench and #10 is still standing next to her coach.
The Roller Derby team that Jill has joined is named the "Tornadoes" (with an "e"). Their jackets read as such. Yet, when Bosley, Kelly and Sabrina arrive at the arena for the bout, the marquee, in part, reads "Tornados" (without the "e").
BTW, due to a very convenient, empty parking space, Bosley is able to park right in front of the arena, regardless of any spelling issues.
Kelly is driving a rental car... a dark-brown, two-door Ford. Unbeknownst to her, the brakes lines have been cut, and she is "all over the road." On that open road, a light-green car approaches and (quite needlessly) "slams on brakes." Kelly's car has changed from a dark-brown, two-door Ford in to a black, four-door car (a Cadillac, it appears).
A moment later, Kelly is driving her rental car (the Ford) once again.
The Roller Derby helmet that Jill wore was so small and so poorly placed on her head that it would have hardly offered her any protection. It is possible that Jill's extreme amount of hair would provide all the protection that she would ever need.
In the beginning of the episode, Kelly's Mustang is blown up. At the end of the episode, when they all come back to Detective Agency, Kelly's Mustang is parked out front! Kelly even asks Charlie about how it is going on getting her a new car.
Ms. Farmer describes Kelly's Mustang II as having a brown top. The top on Kelly's Mustang II is black.
The roller derby coach notices the police and starts to flee but behind him are men dressed as roller derby players even though we are watching a women's roller derby match.
After crashing through a fence and ending up in hay bales, Kelly talks to Sabrina on her car phone. Sabrina asks, "What is it with you and cars, Kelly?" Hypocritically, Sabrina forgets that Bosley, in an earlier episode, complained about Sabrina herself "cracking up" two company cars within a month.
When Kelly's car blows up you can see a split second before it blows up they angle of the shot changes and it's a first gen mustang not the one she drives.
Mrs. Farmer describes to Jeremy the Model and color of Kelly's car, but the only info about the car that Red Loomis provides seconds beforehand is the license plate number of her car.
Bosley drives Sabrina/Kelly to the roller rink late in the episode. As the car drives by a parking lot a second camera can be seen near the road as they are filming from two different angles.
When Kelly's car is blown up, it is unclear how Charlie, who is talking with her on a car phone from an undisclosed location, scolds her to retrieve the suitcase after she initially jets out of the car without taking the suitcase with her. Charlie is presumably not within visible distance, since Kelly diverted onto a random road to abandon the car.
Charlie tells Kelly that there is a bomb planted on her car, though it's never explained how he knew about it to be able to warn her and she, nor anyone else asks how did he know.
After Kelly drives away from the terminal with the suitcase of money, Charlie speaks to her on her carphone to warn her someone planted a bomb on her car. Although the script doesn't clarify this, the viewer may conclude Charlie must've been watching the bomb get planted while Kelly was inside the terminal. But this begs the question why he would endanger Kelly by letting her get in her car in the first place, and drive away.
