Sadie brings Amy to her home and introduces her to music. As time passes, Clarence and Steven become best friends later on. With Jeff, he gets information from Garnet about their history for "personal reasons". As with Sumo, Amethyst takes him on a mission. Both Chad and Greg return back with a gas canister for the car, having to find the engine killed after all that driving.

Meanwhile with Sadie, she gets Amy to sing "Haven't You Noticed (I'm A Star)", and right off the bat she recognized the lyrics and had a better sing voice than her. Sadie became jealous. Pearl and Mary return from seeing a matinee, but Mary was less than pleased. Amethyst and Sumo return from their mission, and Sumo brings back a living Centipeetle, but it gets loose around the town after showing Clarence and Jeff. Fortunately, they catch it in time and destroy it.

Unfortunately, the Centipeetle had destroyed half the town, leading them to return to Aberdale. Sadie gives Amy her CD as to remember her. After Steven and Clarence say their goodbyes, he gives him his mother's portrait with his face drawn on it. Steven becomes angered at what he did to it, which ends their friendship. He later apologizes to Clarence for his outburst, but he doesn't except his apology. They later sit at the beach and talk about their differences. After their conversation, they respect their opinions and agree to remember each other. After returning home, Jeff had gotten a B- on his report, and Clarence pretends that he is still mad and over Steven, but secretly misses him.
