Other mistake: In this episode, the Spellmens and Salem are sitting at the breakfast table. You can see Sabrina has a stack of pancakes in front of her. But in the episode Pancake Madness, they are forbidden in the Spellman home because of the effects that come from them.
Continuity mistake: Miles only learns to drive in this episode, however, in the early episode "I, Busybody" (not aired out of production order), Miles fights a speeding ticket, indicating he had no fear of driving, knows how to drive, and has a driver's license.
Continuity mistake: At the end of the episode when Morgan tells Sabrina she will be working in the coffee house with her, she put on the apron and its the right way, then it flashes back to when she says "we're gonna have so much fun together" and the apron is on backwards with the label sticking out.
Other mistake: After Salem and Sabrina are shrunk down into the toy plane you see the kitchen from inside the cockpit, but when they are shrunk down to be tiny enough to go into Libby's nose, the view from inside the cockpit is the same as it was before they were shrunk down even further. Since they are that much smaller everything should be seen as much bigger.
Continuity mistake: When Sabrina comes back from dream dropping on Harvey, there is a picture of her on her family secret board. Later after her aunts try to get her to solve the family secret, she says she got a new clue. It was the picture of her and she hung it on her board.
