Cartoon Network’s Steven Universe ran its first full “musical episode” titled “Mr. Greg” on July 19, and one of the episode’s songs, “It’s Over, Isn’t It,” has everyone talking. The lyrics have been viewed almost 20,000 times, making it one of the biggest new songs on Genius this week.

For those who don’t follow the show, here’s a quick recap: Steven is the son of a human man and a “gem,“ an advanced alien race with superpowers. A group of these gems (the Crystal Gems: Rose Quartz, Pearl, Garnet, and Amethyst) chose to remain on Earth and protect the planet from the not-so-nice gems that still want to harvest the planet for their own use. Steven’s mother, Rose Quartz, gave up her physical form to help create him. Steven is part human and is learning how to harness his gem’s powers with the other Crystal Gems while also uncovering the secrets of his alien heritage.

In “Mr. Greg,” Steven’s dad—former aspiring rockstar, Greg Universe—comes into some money after one of his old songs was sold as a jingle for a burger company. Together, he, Steven, and Pearl celebrate with a lavish trip to Empire (read: New York) City. Pearl has trouble getting into the spirit of the trip, and finally reveals the reason in a dramatic number that forms the heart of the episode:

This song is a culmination of 86 episodes worth of character development for Pearl. She was in love with Steven’s mom and fans have had hints of her lingering feelings of grief and unrequited love, but here, she finally, explicitly revealed them. In the song “It’s Over, Isn’t It,” she sings:

Who am I now in this world without her?

Petty and dull, with the nerve to doubt her

What does it matter? It’s already done

Now I’ve got to be there for her son

Throughout the series, Pearl has been very resentful of Greg for winning Rose’s heart. The whole episode, but this song in particular, functions as the lancing of that wound—they broke it open, drained it, and stitched it up again in a way where it will heal properly—allowing everyone to move forward.

This scene also marks another explicit portrayal of same-sex love on the show. So far, all gems present as female and three major characters are known to be romantically attracted to other gems: Ruby, Sapphire, and Pearl. In fact, Rose Quartz is still the only gem who is portrayed as “straight."

Steven Universe has featured many big musical names: Estelle voices a primary character (Garnet) and Nicki Minaj has provided her voice for a one-off role. You can read all of the lyrics to “It’s Over, Isn’t It” on Genius now.
