This episode serves as a lesson on the boundaries of humor. Peridot, eager to fit in and seeking approval from Amethyst, begins mocking the other Crystal Gems. She "goes too far" when she shifts from making jokes to listing Amethyst's biological "defects" from a clinical Homeworld perspective, unaware that she is touching on Amethyst’s deep-seated insecurities.

It is revealed that Amethyst stayed in the ground 500 years too long, resulting in her being an "overcooked" and smaller version of what should have been a standard Quartz soldier like Jasper.

She identifies the injectors at the Kindergarten as "Era 1" models.

This was the final episode of 2015 before the show went on its winter hiatus.
