Continuity mistake: When Amethyst takes a picture of herself to set as the wallpaper for Pearl's phone, she's holding the phone in her right hand, with her left hand on the back of her head. Later in the episode when Steven retrieves the phone and the picture is seen, Amethyst is holding the phone with her left hand, with her right hand on the back of her head.
Continuity mistake: When Peridot is looking for parts for the machine, she pulls the microwave from its mounting below the kitchen cabinet and drops it on the counter. After Steven stops her from wrecking the house by telling her he has a better idea, the next shot of the Crystal Gems shows the microwave behind them in its original position.
Continuity mistake: When White Diamond, while controlling Blue Diamond, is talking about how the latter's impurities absorb all of the warmth in her spectrum, Blue's gemstone is depicted as triangular instead of its actual appearance as a diamond-shaped point cut.
