Continuity mistake: In the scene where Rube shakes hands with the animal protesters, he is not wearing the trash bag while shaking their hands. He is wearing the trash bag immediately before and after. (00:04:45)
Suggested correction: He is wearing the trash bag because one of the posters commits on it.
Plot hole: People who do not have their souls retrieved, before they are killed, will suffer the effects of the death on their soul, eg. the autopsied man has scars and cuts on his soul. So how come the woman who was crushed by a piano (whose soul was only ever retrieved afterwards) is unharmed in soul form?
Continuity mistake: After George dodges the toad on the floor, she walks backwards up onto some steps, yet she walks up the same step twice.
Continuity mistake: When Rube and Betty are speaking to George at the site of her death, Betty's scarf continuously changes positions.
Continuity mistake: When Mason and George are about to go into the house of the murdered accountant they show the lock from the inside of the apartment and it's unlocked. When they show it again it's locked and then Mason unlocks it.
Continuity mistake: When George delivers the files to some guy, while at her job, her hair keeps on changing position over her shoulder.
Continuity mistake: When George is filing, she is told it is her lunch hour. Between shots her hair flips over her shoulder.
Continuity mistake: George drops the red file from her stack of files to deliver, yet in the next shot you can still see the red file in the stack.
Continuity mistake: When George is flicking through files in a drawer, they change positions between shots, when the man tells her its her lunch hour.
Revealing mistake: Reapers look 'different' in reflections and recordings, yet sometimes you can catch them with 'normal' reflections, eg. Rube in the diner window.
Continuity mistake: When the first Reaper who touched George magically disappears, people in the background appear out of nowhere and disappear out of nowhere.
Continuity mistake: When George is sitting on the train, watching the little girl she is supposed to reap, the position of the ticket on the seat beside her changes.
Continuity mistake: When Betty is leaving the diner table to meet someone, she puts her bag on her shoulder. In the next shot, it's in her hands.
Continuity mistake: When Rube sits down on the bus station bench, before George gets on the train, to reap her first person, he crosses his legs twice.
Continuity mistake: When George writes "moist" on the fridge, to give her mum a sign, the position of the 'T' magnet changes between shots.
Factual error: Towards the end of the episode, Mason reads a report on Daisy's death indicating she died 13 December 1938 in Marietta Georgia of smoke inhalation. It apparently was common knowledge that Daisy died on the set of Gone with the Wind (supported in the Halloween episode by someone who knew her when she was alive). The filming of the big fire scene in GWTW was 10 December 1938 so the dates are pretty close. But these early parts of the production of GWTW (and I believe the rest of the movie as well) were filmed in Culver City, CA, not Marietta. (00:34:50)
Other mistake: In the copy room, George, after she speaks with Daisy in voice over, says "its 3am", but the clock on the wall behind Crystal shows 12:35 when George talks to Crystal.
Revealing mistake: When Mason and George walk up to the TV's in the store, the TV images do not match Mason and George's movements, as it records them.
Continuity mistake: When everyone is lying on the bank floor during the robbery, George crawls over to Mason. In the following shot she is back where she was before.
Continuity mistake: When George delivers the files to the guy at work, the top file on the stack changes positions between shots.
