Continuity mistake: Velma and Daphne are back to back on the corridor, hearing the spooky sounds. Velma moves away and just looks at her with her arms crossed. When Daphne says "Sounds like a ghost", Velma's reaction shot shows her with her arms down her body. (00:13:20)
Continuity mistake: The dynamic duo sees Spencer in front of the locker secret passage. There is a clock right above him, and the minute hand points at 40 minutes. When Daphne's dad bumps into them, it's quarter past six. (00:14:05)
Continuity mistake: Velma runs away from Daphne and her pouncing dad, and bumps into (not literally this time) Two-Mop Maggie. Her namesake cleaning tools are held at different angles during the conversation that ensues. (00:14:45)
Other mistake: Daphne's dad drops the Legitimate Tulip badge in front of her so she'll avoid getting hurt, but when we see him do that, he does it before the warning for the ball is heard and seemingly not looking at the danger (especially in the second shot, when he is peeking from the corner). So his action makes no sense. (00:16:55)
Continuity mistake: When we see Daphne retrieving sushi from the cafeteria (and it's unveiled that it was her dad in drag who passed it to her), the two nigiri pieces are oriented differently in the tray compared to the close-up. (00:17:00)
Character mistake: Daphne's mother is the one who pressed her husband to tell her the truth, but she is cheering when he says about the basketball anecdote that it was 'real', when later he corrects himself saying "real-ly me, disguised as a mascot." (00:17:25)
Other mistake: Daphne is crying in her room and texts Velma. The message has a "Read" time stamp saying 9:33, followed by Velma "typing" in response at 9:32. (00:18:40)
Continuity mistake: A sad Daphne stands from her bed and says "I guess I'm just on my own now." She sits at the computer, and in the very first shot her ambiguously shaped Hitachi microphone thingy is lying on the desk, in front of her yellow notebook. Close-up, and she fetches it right from on top of the notebook. (00:18:55)
Continuity mistake: On her first day on her own, Daphne steps out of the bus, and in some mucky sweet on the ground. In close-up the pink sweets is of a paler pink than what was used in the other shots. (00:20:30)
Continuity mistake: Daphne talks to Carol about her dad being her clothing closet and she helps her with the technological T-shirt. Throughout the scene you can see the same extras being recycled doing a meaningless back and forth, and bearing some inconsistencies. For instance when we see her hand the shirt, and when a few seconds later after she messes with the phone the color swatch HUD pop up, the same guy with a beanie hat walk in twice. (00:20:50 - 00:21:30)
Continuity mistake: Daphne gets shoved onto Carol on her second day of school. She comments about plum and sage being a "bold color choice"; Daphne's hand is raised all of a sudden at the cut. (00:20:50)
Continuity mistake: When Carol demonstrates the various texturing options, different takes of the same angle have been used, since Daphne holds the changeable T-shirt with her finger sticking into the neck or not between cuts. (00:21:05)
Continuity mistake: Daphne is looking at the bun with suspicious looking meaty mush; in the close-up the milk carton is almost perfectly aligned with the tray, while it's at an angle when she gets bumped into by the random guy (something even her dad could never prevent from happening, incidentally). (00:21:40)
Continuity mistake: Once Daphne gets splashed with water on her shoulder at the cafeteria, she shows up at the laboratory with her shirt more wet than earlier. The water stain is even bigger by the time she sits with Velma. (00:21:45 - 00:31:40)
Factual error: Daphne gets a bit of water spilled on her from a glass at lunch, and she stays with the wet patch (which is just water, as stated) throughout the whole day, arriving at home when it's dark with the same wet spot visible. With all the toweling she did, and even simply by body temperature, the little dampness should have been dry by the end of the afternoon. (00:21:50 - 00:31:40)
Continuity mistake: Daphne arrives at the laboratory for the CO2 experiment, and finds Spencer licking a pipette. Which is held with the left hand, turning into the right hand for the close-up. (00:22:10)
Revealing mistake: When Velma sabotages the science project making it explode into purple goo, you can see that the vial of chemicals she tampered with simply spray around clean liquid, and the purple goo falls from above. (00:23:55)
Continuity mistake: Daphne and Velma's lab coat is a complete mess in the last shot of their fight, all of a sudden, and it's much less messy when they visit the principal (theoretically they could have changed coats offscreen, but then why showing up in the office with the dirty lab coat to begin with?). (00:24:10)
Continuity mistake: When the Conflict Couch's "extreme mode" is activated, its armrests slide closer to both Daphne and Velma. They move independently from the blocks forming the back. However, when Aunt Piper grabs the Timothy Bot ball saying "Hang in there", the armrest block close to Daphne is perfectly aligned with the back of the couch. (00:26:15)
