Peridot gifts Lapis Lazuli the same tape recorder Steven gave her when she first arrived on Earth. Lapis rebuffs the gesture, and Peridot, who is upset that Lapis won't even give her a chance, remarks "What, were you trapped in a tape recorder, too?!" Peridot didn't mean to be malicious, but Lapis actually was trapped in a tape recorder, making this a faux pas on Peridot's part; When Lapis was trapped in the mirror earlier in the series, she could only communicate by repeating things she heard or saw around her, essentially making her a high-tech, sentient tape recorder.
